Need a new DLL patch for using MPLAB ICD 2 on Windows 7 x64.

MPLAB v8.40

Windows 7 Ultimate 64 bit.

johnmx

Can I use this patch on Windows 7 32-bit version.

My new ICD3 is working fine on a XP machine but not in my laptop with Windows 7.

chris.ess

bump..

me too, especially as my Real ICE doesn t work either.

Cheers.

John,

This patch was made because we had problems only on Windows 7-64 bit. Windows 7-32 bit should work without having to use the box and we have tested that. Can you give us some more information about your laptop. Which version of MPLAB IDE are you using and did you install it with admin privileges.

Chris,

I have responded to your question about error while registering the DLL file under the MPLAB REALICE forum topic.

Thanks.

Bme

My ICD2 is not reconized by windows 7 64bits, no setup wizard appear whan I plug ICD2, just USB peripheral not reconized.

I m using mplab 8.43, I have tryed to update manually driver but nothing better.

I did not find the DLL patch as you indacete, I suppose it is included in MPLAB 8.43.

There is a new DLL patch for using MPLAB ICD3 and MPLAB REALICE on Windows 7-64 bit on the web. This patch with the instructions to download it is in a zip file on the MPLAB Page on the Microchip website.

The link for that is here -

SS_GET_PAGE nodeId 1406 dDocName en019469 SW007002

I can t find it.

According to the release notes my ICD 3 should work with MPLAB 8.43 on my new laptop which has Win7-64 bit, but there is a problem with the USB driver: I don t get the Found New Hardware Wizard, and the red ICD 3 Status LED is flashing. The driver is missing, according to the Control Panel.

I ll raise a support ticket.

My PICkit 2 works with the new laptop, at any rate.

After a lot of messing about I found the cause of the problem. The driver has to be installed manually this seems to be a bug, and the Drivers64 directory has to be selected,not the lower level Win7_64 directory.

When manually installing the driver windows says The file does not contain a compatible driver for your device. If the folder contains a driver make sure it is designed to work with Windows for 64-bit processor

Who has any idea to solve my problem.

I am getting pretty frustrated with trying to get my Win7 new HP laptop working with the ICD2. I tried all of the above suggestions and still get no driver message when trying to update the driver. The driver is there in the right directory, but doesn t get recognized when either the directory or the directory a level up.

Another thing I noticed was that all the Microchip stuff is located in the Program Files x86 not in. the Program Files directory. I don t know if this is a problem or not.

Some help. I have spent all day on this with no luck.

Neal

Bme:

What files do you have in the Drivers64 directory. I ll check them against mine.

post edited by leon_heller - 2010/02/03 :47

The Drivers64 directory has:

Win7_64

mchpusb

mchpusb.sys

mchpus64.sys

ReadMe

The Win_64 directory has ddwin764.htm as its first file.

Does that match yours.

Thanks

They look the same as mine, so should work OK.

Are you also using an ICD2 and not an ICD3. If you are using an ICD2 what is the P/N number on the back. Mine is P/N 10-00319 R13. The reason I ask is that I thought I once saw that certain versions of the ICD2 will not work.

I m using an ICD 3.

samandro

I have windows 7 64 bit

all the drivers on the CD do not support this windows version

how can i get the usb driver of the ICD 2 for windows 7 64 bit.

Try the ICD 3 patch mentioned at the beginning of the thread. If that doesn t work it s probably best to raise a support ticket.

10-00319 is based on Cypress USB chips and will not be supported by Vista 64bit and Windows 7 64bit as per Microchip.

Those newer ICD2 based on PIC18F4550, 10-00397 will be supported.

ORIGINAL: Developer Moderator

64-bit VISTA is now supported by newer MPLAB ICD 2 debuggers P/N 10-00397. Please follow instructions on installing the drivers in the MPLAB ICD 2 release notes. These are the RoHS compliant devices.

Older MPLAB ICD 2 debuggers P/N 10-00319 will NOT support 64-bit VISTA.

I have the ICD3 working just fine on a Windows XP machine. I am now attempting to migrate my project over to my new Windows 7 64 bit. I have been unsuccessful in my attempts. I installed MPLAB IDE v8.50 and then manually installed the drivers. I cannot get my computer to talk to the ICD3. I keep getting the following errors:

MPLAB ICD 3 detected

Connecting to MPLAB ICD 3

Running self test

Self test completed

Firmware Suite Version 01.20.14

Firmware type.dsPIC30F

Downloading RS

ICD3Err0021: Command not echoed properly. Sent 3f, received

800.

ICD3Err0024: Download RS Failed

Failed to properly connect to ICD 3

I can hook this ICD 3 up to the XP machine and I don t have any problems no problems, connecting, programming, debugging are all fine. I figure because I have 8.50 I already have the dll fix. Any suggestions.

Yes, something is wrong when running Windows 7 pro with x86 mode.

I have the ICD 3 P/N 10-00421-RC and I can t find a USB driver for it. I tried both the MPLAB IDE V8.36 disk that came with the kit and the Explorer 16 V5.0 disk.

I installed MPLab IDE V8.50 thinking this would help. But I see the same problems as the other posters. Windows 7 can t find a driver even when I manually look for it in the folder C: Program Files x86 Microchip MPLAB IDE ICD3 Drivers.

I wish I knew what the name of the driver was because I suspect it is in another folder in MPLAB IDE.

I can confirm this.

I have two IDC2 s one quite old and one fairly new, the older one WIN7 64 proffesional wouldn t recognize. While the newer worked, well not quite the way as told in the various documentation for WIN 7 setup, but ended up working.

The older I never got working WIN 7 simply wouldn t recognize a driver for it.

Sadly enough since the older ICD2 is still going strong, at least on XP. The casing is so worn out that the P/N isn t readable anymore.

The newer has: 10-00397-R3

A PIC listens to your commands -not your intentions.

I have Windows 7 Professional 64 bit and I loaded MPLAB. It automatically loaded into the Program Files x86 folder. I have the ICD3 and I had trouble following the installation instructions. I did finally get it working. So here are the steps needed to get MPLAB to find the ICD3.

Use the Device Manager in the Control Panel to update the driver for the Microchip USB Device. Use the browse option to find the USB driver file C: Program Files x86 Microchip MPLAB IDE Drivers64 mchpusb64.sys. Once this is installed then MPLAB will find the ICD3.

It took me a long time to find out that the USB driver file was mchpusb64.sys. I could not find this in the documentation.

hello,

I have the same problem :

I use Windows 7, I have the ICD 2 P/N 10-00397-R4 and I can t find the USB driver

I installed MPLAB IDE V8.50

I tried the link sent by H H first post but i didn t find the patch

Do you have any ideas.

Thank you for your help

BikG

Good morning,

I ve been using ICD2 for a few months on Win7-64 without problems. I had to switch to ICD3 and I m having problems. A similar post was made but didn t seem to have been resolved so here I go:

- Win7-64 with MPLAB v8.46 Tried the previous version and the newest v8.56. Results below are from 8.46

- Manually installed the drivers from the proper 64bit folder

- Manually upgraded the ICD3 firmware for the tested version of MPLAB

I get the following when trying to use the test board:

Firmware Suite Version 01.25.20

Firmware type.PIC32MX

MPLAB ICD 3 Connected.

ICD3Err0045: You must connect to a target device to use

MPLAB ICD 3.

ICD3Err0033: 4 bytes expected, 0 bytes received

ICD3Err0057: Interface test could not be completed.

27.

The same kit was tested on XP and works fine test board, debugging.

If someone was able to resolve this problem I m more than open to suggestions.

Thanks for reading,

BigK

Having problems with Windows 7 pro 64bit and ICD3. MPLAB V8.56.

The driver is the mchpusb64.sys as displayed under the custom USB device driver details.

It locks up trying to connect, at various points. It was working on XP previously of course. I can t select programmer none as it comes back saying the programmer is busy error 5 and I have to restart MPLAB to attempt to connect again. and of course unplug the ICD3.

I m leaving the ICD3 off for 10 - 30 seconds in between restarts.

Configure select device is set to the correct MCU for my app, a dsPIC33FJ128GP804.

Problem resolved

One last restart seems to have done it. I had to restart MPLAB after it said AP download complete, RS download complete, etc But it s come back and detected the board. Leaving this for anyone else having similar issues.

Device Manager tells that ICD 2 P/N 10-00319 plugged into USB has VID_04D8 Microchip and PID_8000. Its PID is not listed in the . . Microchip MPLAB IDE Drivers64 mchpusb.inf file. Apparently this is why I cannot install the driver under Win 7 - 64 bits.

I guess the newer revision of the ICD 2 has PID_8001, and it is listed in the inf file.

When I tried to cheat and added PID_8000 to the inf file, I could install the driver, but ICD 2 did not work anyway. It looks like P/N 10-00319 is really not supported for 64-bit Windows.

----

Update: I have checked the registry of a 32-bit computer with Win XP where ICD 2 P/N 10-00319 is installed. There are 2 PIDs there: PID_8000 described as Microchip MPLAB ICD 2 Firmware Loader, PID_8001 is Microchip MPLAB ICD 2 Firmware Client. When on this machine ICD 2 is plugged into USB, Device Manager shows Firmware Client with PID_8001.

Running Windows 7 pro 64 bit on a SONY VAIO.

I have the ICD 3 P/N 10-00421-RC and I can t install the USB driver for it. I am using trying to MPLAB IDE V8.66 and I have followed all the instructions to manually install the driver from C: Program Files x86 Microchip MPLAB IDE Drivers64, starting from the device manager where ICD3 is viewed as Other Device even tough windows displays the device s name as MPLAB ICD3 tm .

I have administrator rights on my laptop but Windows gives always the same message: Windows found software for your device but encountered an error while attempting to install it .

Any idea that can help.

I have ICD2 P/N 10-00319 and got trouble installing drivers in Win7 64bit.

Please, suggest the solution.

EvFarm

It s been over a year since I bought my ICD3 10-00421-RC. I ve been using it fine on XP32 since it did not initially work on my main Win7_x64 development machine.

But now I really need it on Win7_x64. Using two machines on a KVM is not helpful.

I did a fresh first time for MPLAB install of MPLAB880 on this PC but I just can t get the ICD3 to work.

First off, the ICD3 status in MPLAB was claiming to be version 0.00 so I updated the firmware. That went OK. Then I plugged in the test module and ran that - all OK.

Then I plugged it into my dev board and it detected a PC18FJ just fine.

But any attempt to ICSP my part just get Programming ICD3Err0033; 4 bytes expected, 2 bytes received and then MPLAB crashes I get the Windows dialog with MPLAB IDE has stopped working.

It s 2011. Surely it should work smoothly on Win7_64 by now.

Does anyone have any idea what I m missing.

post edited by EvFarm - 2011/11/19 :49

well. it happened again when installing the latest version of malpab on my machine using window7 pro 64bit. I could not make it working. when looking at the driver s properties in the device manager they say that the driver is the one specify in the. inf file for 64-bit machines but when the ICD3 is plugged in windows keeps saying that the driver installed it is not the right one. the only way to make this thing working was install the XP Mode in my laptop. this sound stupid and it is frustrating indeed. I have been digging the internet for a the entire week end and I could not find a reasonable solution especially from whom is expected to give one microchip..

I wish you all better luck

Hi All,

Although not perfect you can still use an old 10-00319 R12 ICD2 on a Win7x64 box.

If you want a little trick to workaround the unsupported device have a look on my site.

Hi,

we cannot find any patch at this link.

As this link was posted in 2009 is it still relevant to the latest versions of MPLABX, ICD3 and Real Ice equipment running on Window 7 64 bit.

If not then the post should be removed to save people spending time looking for it

Sorry I have never heard of Microchip reveiwing old posts to see if they are still current.

Or current Post to see if they are correct.

This is a User forum.

I would seriously doubt it still applies, But wait from mor input.

Thanks for reading such an old post. At least by replying to the post we have brought it up the list.

I accept your response, but forum members looking for answers to this issue come across this post and then spend time trying to figure out where the non-existent link is. Would not be rocket science for MC or a super member to add a quick post that this is no longer relevant.

How to Fade Acne Scars. Acne is enough of an issue on its own, so it seems unfair that long after the blemish has healed you re left with angry scars to remind you.

Acne in a 14-year-old male during puberty

This article is about a skin disease common during adolescence. For other acneform skin diseases, see Acne disambiguation.

Acne vulgaris or simply acne is a long-term skin condition characterized by areas of blackheads, whiteheads, pimples, greasy skin, and possibly scarring. 1 2 The resulting appearance may lead to anxiety, reduced self-esteem, and in extreme cases, depression or thoughts of suicide. 3 4

Genetics is estimated to be the cause of 80 of cases. 2 The role of diet as a cause is unclear. 2 Neither cleanliness nor sunlight appear to be involved. 2 However, cigarette smoking does increase the risk of developing acne and worsens its severity. 5 Acne mostly affects skin with a greater number of oil glands including the face, upper part of the chest, and back. 6 During puberty in both sexes, acne is often brought on by an increase in androgens such as testosterone. 7 Excessive growth of the bacteria Propionibacterium acnes, which is normally present on the skin, is often involved. 7

Many treatment options are available to improve the appearance of acne including lifestyle changes, procedures, and medications. Eating fewer simple carbohydrates like sugar may help. 8 Topical benzoyl peroxide, salicylic acid, and azelaic acid are commonly used treatments. 9 Antibiotics and retinoids are available topically and by mouth to treat acne. 9 However, resistance to antibiotics may develop. 10 A number of birth control pills may be useful in women. 9 Oral isotretinoin is usually reserved for severe acne due to greater potential side effects. 9 Early and aggressive treatment is advocated by some to lessen the overall long-term impact to individuals. 4

Acne occurs most commonly during adolescence, affecting an estimated 80вЂ 90 of teenagers in the Western world. 11 12 13 Lower rates are reported in some rural societies. 13 14 In 2010, acne was estimated to affect 650 million people globally making it the 8th most common disease worldwide. 15 People may also be affected before and after puberty. 16 Though it becomes less common in adulthood than in adolescence, nearly half of people in their twenties and thirties continue to have acne. 2 About 4 continue to have difficulties into their forties. 2

Classification edit

Acne is commonly classified by severity as mild, moderate, or severe. This type of categorization can be an important factor in determining the appropriate treatment regimen. 12 Mild acne is classically defined as open blackheads and closed comedones whiteheads limited to the face with occasional inflammatory lesions. 12 Acne may be considered to be of moderate severity when a higher number of inflammatory papules and pustules occur on the face compared to mild cases of acne and acne lesions also occur on the trunk of the body. 12 Lastly, severe acne is said to occur when nodules and cysts are the characteristic facial lesions and involvement of the trunk is extensive. 12

Signs and symptoms edit

Typical features of acne include seborrhea increased oil secretion, microcomedones, comedones, papules, pustules, nodules large papules, and possibly scarring. 1 17 The appearance of acne varies with skin color. It may result in psychological and social problems. 12

Some of the large nodules were previously called cysts and the term nodulocystic has been used to describe severe cases of inflammatory acne. 18

Scars edit

Acne scars are the result of inflammation within the dermal layer of skin brought on by acne and are estimated to affect 95 of people with acne vulgaris. 19 The scar is created by an abnormal form of healing following this dermal inflammation. 19 Scarring is most likely to occur with severe nodulocystic acne, but may occur with any form of acne vulgaris. 19 Acne scars are classified based on whether the abnormal healing response following dermal inflammation leads to excess collagen deposition or collagen loss at the site of the acne lesion. 19

Atrophic acne scars are the most common type of acne scar and have lost collagen from this healing response. 19 Atrophic scars may be further classified as ice-pick scars, boxcar scars, and rolling scars. 19 Ice pick scars are typically described as narrow less than 2 mm across, deep scars that extend into the dermis. 19 Rolling scars are wider than ice pick scars 4вЂ 5В mm across and have a wave-like pattern of depth in the skin. 19 Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5вЂ 4В mm across. 19

Hypertrophic scars are less common and are characterized by increased collagen content after the abnormal healing response. 19 They are described as firm and raised from the skin. 19 20 Hypertrophic scars remain within the original margins of the wound whereas keloid scars can form scar tissue outside of these borders. 19 Keloid scars from acne usually occur in men and on the trunk of the body rather than the face. 19

Pigmentation edit

Postinflammatory hyper pigmentation PIH is usually the result of nodular or cystic acne the painful bumps lying under the skin. They often leave behind an inflamed red mark after the original acne lesion has resolved. PIH occurs more often in people with darker skin color. 21 Pigmented scar is a common but misleading term, as it suggests the color change is permanent. Often, PIH can be avoided by avoiding aggravation of the nodule or cyst. These scars can fade with time. However, untreated scars can last for months, years, or even be permanent if deeper layers of skin are affected. 22 Daily use of SPF 15 or higher sunscreen can minimize pigmentation associated with acne. 22

A severe case of cystic acne

Cystic acne on the back.

Acne vulgaris types: A: Facial cystic acne, B: Subsiding tropical acne of trunk, C: Extensive chest and shoulder acne.

Cause edit

Genetic edit

The predisposition for specific individuals to acne is likely explained in part by a genetic component, which has been supported by twin studies as well as studies that have looked at rates of acne among first degree relatives. 23 The genetics of acne susceptibility is likely polygenic, as the disease does not follow classic Mendelian inheritance pattern. There are multiple candidates for genes which are possibly related to acne, including polymorphisms in TNF-alpha, IL-1 alpha, and CYP1A1 among others. 11

Hormonal edit

Hormonal activity, such as menstrual cycles and puberty, may contribute to the formation of acne. During puberty, an increase in sex hormones called androgens cause the follicular glands to grow larger and make more sebum. 6 24 A similar increase in androgens occurs during pregnancy, also leading to increased sebum production. 25

Several hormones have been linked to acne including the androgens testosterone, dihydrotestosterone DHT and dehydroepiandrosterone sulfate DHEAS, as well as insulin-like growth factor 1 IGF-I and growth hormone. 26 Use of anabolic steroids may have a similar effect. 27

Acne that develops between the ages of 21 and 25 is uncommon. 28 True acne vulgaris in adult women may be due to pregnancy or polycystic ovary syndrome. 29

Infectious edit

Propionibacterium acnes P. acnes is the anaerobic bacterium species that is widely suspected to contribute to the development of acne, but its exact role in this process is not entirely clear. 23 30 There are specific sub-strains of P. acnes associated with normal skin and others with moderate or severe inflammatory acne. 31 It is unclear whether these undesirable strains evolve on-site or are acquired, or possibly both depending on the person. These strains either have the capability of changing, perpetuating, or adapting to, the abnormal cycle of inflammation, oil production, and inadequate sloughing of acne pores. One particularly virulent strain has been circulating in Europe for at least 87 years. 32 Infection with the parasitic mite Demodex is associated with the development of acne. 17 33 However, it is unclear if eradication of these mites improves acne. 33

Lifestyle edit

Cigarette smoking is known to increase the risk of developing acne. 5 Additionally, acne severity worsens as the number of cigarettes a person smokes increases. 5 The relationship between diet and acne is unclear as there is no high-quality evidence. 34 However, a high glycemic load diet is associated with worsening acne. 8 35 There is weak evidence of a positive association between the consumption of milk and a greater rate and severity of acne. 33 36 37 38 Other associations such as chocolate and salt are not supported by the evidence. 36 Chocolate does contain a varying amount of sugar that can lead to a high glycemic load and it can be made with or without milk. There may be a relationship between acne and insulin metabolism and one trial found a relationship between acne and obesity. 39 Vitamin B12 may trigger acneiform eruptions, or exacerbate existing acne, when taken in doses exceeding the recommended daily intake. 40

Psychological edit

While the connection between acne and stress has been debated, research indicates that increased acne severity is associated with high stress levels. 41 42

Acne excorie is a type of acne in which a person picks and scratches pimples due to stress. 43

Pathophysiology edit

Hair follicle anatomy

Acne develops as a result of blockages in the skin s follicles. These blockages are thought to occur as a result of the following four abnormal processes: a higher than normal amount of sebum production influenced by androgens, excessive keratin deposition leading to comedone formation, colonization of the follicle by Propionibacterium acnes bacteria, and the local release of pro-inflammatory chemicals in the skin. 31

The earliest pathologic changes are the excessive deposition of the protein keratin and oily sebum in the hair follicle resulting in the formation of a plug a microcomedo. 6 During adrenarche, a higher level of the androgen DHEA-S results in the enlargement of the sebaceous glands and increases sebum production. A microcomedo may enlarge to form an open comedo blackhead or closed comedo. The dark color of a blackhead occurs due to oxidation of the skin pigment melanin. 12

Comedones result from the clogging of sebaceous glands with sebum, a naturally occurring oil, and dead skin cells. 6 In these conditions, the naturally occurring largely commensal bacterium Propionibacterium acnes can cause inflammation within and around the follicle, leading to inflammatory lesions papules, infected pustules, or nodules in the dermis around the microcomedo or comedone, which results in redness and may result in scarring or hyperpigmentation. 6 44 45 Severe acne is inflammatory, but acne can also be noninflammatory. 28

Diagnosis edit

There are multiple scales for grading the severity of acne vulgaris, 46 three of these being:

Leeds acne grading technique: Counts and categorizes lesions into inflammatory and non-inflammatory ranges from 0вЂ 10.0.

Cook s acne grading scale: Uses photographs to grade severity from 0 to 8 0 being the least severe and 8 being the most severe.

Pillsbury scale: Simply classifies the severity of the acne from 1 least severe to 4 most severe.

Differential diagnosis edit

Similar conditions include rosacea, folliculitis, keratosis pilaris, perioral dermatitis, and angiofibromas among others. 12 Age is one factor that may help a physician distinguish between these disorders. Skin disorders such as perioral dermatitis and keratosis pilaris can mimic acne but tend to occur more frequently in childhood whereas rosacea tends to occur more frequently in older adults. 12 Facial redness triggered by heat or the consumption of alcohol or spicy food is suggestive of rosacea. 47 The presence of comedones can also help health professionals differentiate acne from skin disorders that are similar in appearance. 9

Management edit

Many different treatments exist for acne including benzoyl peroxide, antibiotics, retinoids, antiseborrheic medications, anti-androgen medications, hormonal treatments, salicylic acid, alpha hydroxy acid, azelaic acid, nicotinamide, and keratolytic soaps. 48 They are believed to work in at least four different ways, including the following: normalizing skin cell shedding and sebum production into the pore to prevent blockage, killing P. acnes, anti-inflammatory effects, and hormonal manipulation. 6

Commonly used medical treatments include topical therapies such as retinoids, antibiotics, and benzoyl peroxide and systemic therapies including oral retinoids, antibiotics, and hormonal agents. 12 49 Procedures such as light therapy and laser therapy are not considered to be first-line treatments and typically have an adjunctive role due to their high cost and limited evidence of efficacy. 49

Medications edit

Benzoyl peroxide edit

Benzoyl peroxide cream

Benzoyl peroxide is a first-line treatment for mild and moderate acne due to its effectiveness and mild side-effects mainly irritant dermatitis. It works against P. acnes, helps prevent formation of comedones, and has anti-inflammatory properties. 6 Benzoyl peroxide normally causes dryness of the skin, slight redness, and occasional peeling when side effects occur. 50 This topical does increase sensitivity to the sun as indicated on the package, so sunscreen use is often advised during the treatment to prevent sunburn. Benzoyl peroxide has been found to be nearly as effective as antibiotics with all concentrations being equally effective. 50 Unlike antibiotics, benzoyl peroxide does not appear to generate bacterial resistance. 50 Benzoyl peroxide may be paired with a topical antibiotic or retinoid such as benzoyl peroxide/clindamycin and benzoyl peroxide/adapalene, respectively. 21

Antibiotics edit

Topical antibiotics are frequently used for mild to moderate severe acne. 12 Oral antibiotics are indicated for moderate to severe cases of inflammatory acne and decrease acne due to their antimicrobial activity against P. acnes in conjunction with anti-inflammatory properties. 6 12 50 They are believed to work both by decreasing the number of bacterial and as an anti-inflammatory. 2 With increasing resistance of P. acnes worldwide, they are becoming less effective. 50 Commonly used antibiotics, either applied topically or taken orally, include erythromycin category B, clindamycin category B, metronidazole category B, and tetracyclines such as doxycycline and minocycline. 25 Topical erythromycin and clindamycin are considered safe to use as acne treatment during pregnancy due to negligible systemic absorption. 25 Nadifloxacin and dapsone are other topical antibiotics that may be used to treat acne in pregnant women, but have received less extensive study. 25 It is recommended that oral antibiotics be stopped and topical retinoids be used once the disease has improved. 9

Salicylic acid edit

Salicylic acid category C 25 is a topically applied beta-hydroxy acid that possesses bacteriostatic and keratolytic properties. 51 52 Additionally, salicylic acid opens obstructed skin pores and promotes shedding of epithelial skin cells. 51 However, salicylic acid is known to be less effective than retinoid therapy. 12 Hyperpigmentation of the skin has been observed in individuals with darker skin types who use salicylic acid. 6

Azelaic acid edit

Azelaic acid has been shown to be effective for mild-to-moderate acne when applied topically at a 20 concentration. 44 Application twice daily for six months is necessary, and treatment is as effective as topical benzoyl peroxide 5, isotretinoin 0.05, and erythromycin 2. 53 Azelaic acid is thought to be an effective acne treatment due to its antibacterial, anti-inflammatory, and antikeratinizing properties. 44 Azelaic acid may cause skin irritation but is otherwise very safe. 54

Hormones edit

In women, acne can be improved with the use of any combined oral contraceptive. 55 The combinations that contain third or fourth generation progestins such as desogestrel, norgestimate, or drospirenone may theoretically be more beneficial. 55 Antiandrogens such as cyproterone acetate and spironolactone have also been used successfully to treat acne. 25 Hormonal therapies should not be used to treat acne during pregnancy or lactation as they have been associated with certain birth defects such as hypospadias and feminization of the male fetus. 25

Topical retinoids edit

Topical retinoids are medications that possess anti-inflammatory properties and work by normalizing the follicle cell life cycle. 6 They are a first-line acne treatment for people with dark colored skin and are known to lead to faster improvement of post inflammatory hyperpigmentation. 21 This class includes tretinoin category C, adapalene category C, and tazarotene category X. 25 Like isotretinoin, they are related to vitamin A, 6 but are administered topically and generally have much milder side effects. They can, however, cause significant irritation of the skin. The retinoids appear to influence the cell life cycle in the follicle lining. This helps prevent the hyperkeratinization of these cells that can create a blockage. Retinol is a form of vitamin A that has similar, but milder effects and is used in many over-the-counter moisturizers and other topical products. Topical retinoids often cause an initial flare-up of acne and facial flushing.

Oral retinoids edit

Isotretinoin is very effective for severe acne as well as moderate acne refractory to other treatments. 12 Improvement is typically seen after one to two months of use. After a single course, about 80 of people report an improvement with more than 50 reporting complete remission. 12 About 20 of people require a second course. 12 A number of adverse effects may occur including: dry skin, nose bleeds, muscle pains, increased liver enzymes, and increased lipid levels in the blood. 12 If used during pregnancy, there is a high risk of abnormalities in the baby and thus women of child bearing age are required to use effective birth control. 12 There is no clear evidence that use of oral retinoids increases the risk of psychiatric side effects such as depression and suicidality. 12

Spironolactone edit

The aldosterone antagonist spironolactone is an effective treatment for acne in adult women, but is not approved by the United States Food and Drug Administration for this purpose. 21 Spironolactone is thought to be a useful acne treatment due to its ability to block the androgen receptor at higher doses. 21 It may be used with or without an oral contraceptive. 21

Combination therapy edit

Combination therapy using medications of different classes together, each with a different mechanism of action, has been demonstrated to be a more efficacious approach to acne treatment than monotherapy. 25 Frequently used combinations include the following: antibiotic benzoyl peroxide, antibiotic topical retinoid, or topical retinoid benzoyl peroxide. 25

Procedures edit

Comedo extraction may temporarily help those with comedones that do not improve with standard treatment. 9 A procedure for immediate relief is the injection of corticosteroids into the inflamed acne comedone. 6 There is no evidence that microdermabrasion is effective. 9

Light therapy is a method that involves delivering intense pulses of light to the area with acne sometimes following the application of a sensitizing substance such as aminolevulinic acid. 56 This process is thought to kill bacteria and decrease the size and activity of the glands that produce sebum. 56 As of 2012, evidence for light therapy and lasers is insufficient to recommend them for routine use. 9 Light therapy is expensive, and while it appears to provide short-term benefit, there is a lack of long-term outcome data or data in those with severe acne. 6 57

Dermabrasion is an effective therapeutic procedure for reducing the appearance of superficial atrophic scars of the boxcar and rolling varieties. 19 Ice pick scars do not respond well to treatment with dermabrasion due to their depth. 19 However, the procedure is painful and has many potential side effects such as skin sensitivity to sunlight, redness, and decreased pigmentation of the skin. 19 The procedure has fallen out of favor with the introduction of laser resurfacing. 19

Laser resurfacing can be used to reduce the scars left behind by acne. 58 Ablative fractional photothermolysis laser resurfacing was found to be more effective for reducing acne scar appearance than non-ablative fractional photothermolysis, but was associated with higher rates of postinflammatory hyperpigmentation usually about 1-month duration, facial redness usually for 3вЂ 14 days, and pain during the procedure. 59

Chemical peels can also be used to reduce the appearance of acne scars. 19 Mild chemical peels include those using glycolic acid, lactic acid, salicylic acid, Jessner s solution, or a lower concentration 20 of trichloroacetic acid. These peels only affect the epidermal layer of the skin and can be useful in the treatment of superficial acne scars as well as skin pigmentation changes from inflammatory acne. 19 Higher concentrations of trichloroacetic acid 30-40 are considered to be medium strength peels and affect skin as deep as the papillary dermis. 19 Formulations of trichloroacetic acid concentrated to 50 or more are considered to be deep chemical peels. 19 Medium and deep strength chemical peels are more effective for deeper atrophic scars, but are more likely to cause side effects such as skin pigmentation changes, infection, or milia. 19

Alternative medicine edit

Numerous natural products have been investigated for treating people with acne. 60 Low-quality evidence suggests topical application of tea tree oil or bee venom may reduce the total number of skin lesions in those with acne. 60 There is a lack of high-quality evidence for the use of acupuncture, medicine, and cupping therapy for acne. 60

Prognosis edit

Acne usually improves around the age of 20 but may persist into adulthood. 48 Permanent physical scarring may occur. 12 There is good evidence to support the idea that acne has a negative psychological impact and worsens mood, lowers self-esteem, and is associated with a higher risk of anxiety, depression, and suicidal thoughts. 33

Epidemiology edit

Globally acne affects approximately 650В million people, or about 9.4 of the population, as of 2010. 61 It affects almost 90 of people in Western societies during their teenage years and may persist into adulthood. 12 Acne after the age of 25 affects 54 of women and 40 of men. 25 Acne vulgaris has a lifetime prevalence of 85. 25 About 20 have moderate or severe cases. 23 It is slightly more common in females than males 9.8 versus 9.0. 61 In those over 40В years old, 1 of males and 5 of females still have problems. 12

Rates appear to be lower in rural societies. 14 While some find it affects people of all ethnic groups, 62 it may not occur in the non-Westernized people of Papua New Guinea and Paraguay. 23

Acne affects 40 to 50 million people in the United States 16 and approximately 3 to 5 million in Australia 23. 63 In the United States, acne tends to be more severe in Caucasians than in people of African descent. 6

History edit

Ancient Egypt, Ancient Greece and Ancient Rome: Sulfur was used to treat acne. 64

1920s: Benzoyl peroxide was used as a medication to treat acne. 65

1970s: Tretinoin original Trade Name Retin A was found to be an effective treatment for acne. 66 This preceded the development of oral isotretinoin sold as Accutane and Roaccutane in 1980. 67 Also, antibiotics such as minocycline are used as treatments for acne.

1980s: Accutane is introduced in the United States, and later found to be a teratogen, highly likely to cause birth defects if taken during pregnancy. In the United States, more than 2,000 women became pregnant while taking the drug between 1982 and 2003, with most pregnancies ending in abortion or miscarriage. About 160 babies with birth defects were born. 68 69

Society and culture edit

Cost edit

The social and economic costs of treating acne vulgaris are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over 2.5 billion each year in direct costs. 5 Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom. 12

Stigma edit

Misperceptions about acne s causative and aggravating factors are common and those affected by acne are often blamed for their condition. 4 Such blame can worsen the affected person s sense of self-esteem. 4 Acne vulgaris and its resultant scars have been associated with significant social difficulties that can last into adulthood. 70

Research edit

In 2007, the first genome sequencing of a P. acnes bacteriophage PA6 was reported. The authors proposed applying this research toward development of bacteriophage therapy as an acne treatment in order to overcome the problems associated with long-term antibiotic therapy, such as bacterial resistance. 71

A vaccine against inflammatory acne has been tested successfully in mice, but has not yet been proven to be effective in humans. 72 Other workers have voiced concerns related to creating a vaccine designed to neutralize a stable community of normal skin bacteria that is known to protect the skin from colonization by more harmful microorganisms. 73

Arduino Serial Output Garbled

Lab: Serial Output from an Arduino to Processing. last edited 30 August 2015 by Tom Igoe. Introduction.

Garbled data output from sensor through XBEE. However my resulting output on the UNO is How to send serial data from arduino to xbee and from xbee to вЂ.

Arduino - garbled serial output. I ve hooked up a ADH8066 Sparkfun GSM Module to my Arduino Uno, and am trying to get some correct serial going between the Arduino.

Ascii text is garbled when Arduino message is displayed in ScripCraft 3. simply want to pipe serial output from the arduino through conversation on GitHub.

Arduino is an open-source electronics prototyping platform the rest of the characters are garbled. This does not happen when using serial speeds lower than.

Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port also known as a UART or USART : Serial.

Serial.read has garbled data after a Serial.write. I had to flush the Arduino serial RX before sending any data pauses execution until the output buffer is.

Hello,

I m having trouble with one of my projects and I m not sure if it s a problem with serial or with power on my Arduino Duemilanova. My basic set up is that I have an ethernet shield on the Arduino and the Rx and Tx pins 0,1 going out to a MAX2322 chip and the MAX2322 connected to a printer. The Arduino checks a webserver for text and prints it on the printer using Serial.print. I have it working great as long as my Arduino is getting its power over USB from my computer. When I unplug the USB and plug in a 9V wall adapter to have it run while disconnected from the PC, the serial printer output is garbled. I thought it was a power issue, so I tried powering the board with just a USB power source, and I get garbled output, or sometimes nothing.

I know that you may need more details to help out, but I wanted to check to see what the first hunches were. Am I looking to fix a power issue or a Serial issue.

Thanks,

Matt

Are you connecting the power to Vin.

Have you connected the grounds correctly.

Is it a 9V DC output AC adaptor.

Can it supply enough current.

Yes, it s a 9V AC to DC Adapter that has worked for other projects, but this is the first time I m using it with the Ethernet Shield and the MAX2322. It might be a current issue, I ll have to play around with it to see what i come up with.

Thanks.

From the symptoms, the most likely cause is a bad ground connection. What pins on the printer do you have connected to the Arduino.

Sorry, I m new at the electronics thing, so pardon me if I m not using the right terminology: I have the - rails on my breadboard hooked up to the ground on the Arduino with the printer s ground and the MAX3232 s ground connected to that, sorry for the bad pic, but here s what the breadboard looks like:

pluggy

Yes, it s a 9V AC to DC Adapter that has worked for other projects, but this is the first time I m using it with the Ethernet Shield

The official ethernet shield is a greedy b gger as far as current goes. It uses around 7-8 times as much power as a naked arduino. If the supply is a bit short of smoothing you could be getting very ragged DC out of it when its feeding the ethernet shield as well as the arduino. If it has a small output,it could be it just isn t man enough for the job.

Thank you everyone for your help. Here s a very basic electricity question: should I then buy a DC adapter that has a higher output voltage or higher output amperes. I know you can supply too much volts to an Arduino. Is it possible to have to have an adapter with too high of an ampere rating.

Based on what I m learning, I think I should get a DC adapter that outputs 12V and then a higher ampere output. I see mouser.com has 12VDC adapters that output anywhere from 100 mA to 2.0 A. Should I just order the 12V 2.0A adapter.

THANK YOU.

Whatever you connect to the power supply will use as much current as it needs upto the limit of the power supply so a higher rated supply will do no harm. A little warning regarding feeding an arduino with an ethernet shield with 12 volts, the arduino s regulator will get hot. 9 Volt is a safer bet if you re using ethernet.

I found a 5V 4.0A power supply and tested the voltage with my multimeter, and I was getting 5.27V. Even with this power supply, I m having the same problems: garbled text.

Could this then be a ground issue. Is there a difference between the ground from the computer powered USB hub, to be accurate and a wall wart.

I decided to test the problem a few other ways. I took a different Arduino Duemilanove board without the ethernet shield and wrote a simple Hello, World. sketch. Under USB power, Hello, World prints fine, but under power from either of my AC adapters 9V 650mA and 5.0V 4.0A, I get no response from the printer most of the time and sometimes garbled text. When I switch back to USB, it might spit out a little bit of garbled text, but then it goes right back to printing Hello World the way it should.

If this is a ground problem, how would i fix it.

Thanks again,

Ok, so Ran Talbott was right, it is a ground issue. I tried powering the Arduino with my wall wart and connecting the USB s ground to the breadboard s ground rail.

Whenever the USB ground is tied into the circuit, it all works perfectly. When I break that USB ground connection, get nothing printed and sometimes garbled text.

If I get an AC-DC adapter that has three prongs that plug into the AC, will this solve my problem. Or is there a way I can fix this this while using the wall warts that I have only two prongs into the AC. I guess I don t totally understand how the ground is being used. My laptop which provides the USB ground only has two prongs going into the wall, so there must be a way, right.

Thank you so much to everyone who helped me out with this. I tried connecting the ground to different pins on the back of the printer and finally found one that worked 100 of the time, no matter what the power source.

For some reason, the serial printer DB9/DB25 pin diagrams I found online don t match the printer that I have and the fact that it worked while powered under USB lead me to believe that I was using the right pins all along.

Now I m back to using the 9V 650mA power adapter that I ordered for the project and it has been working like a champ.

Thank you again for you help,

Matt.

I have a fio v3 a 9DOF sensor hooked up to an XBEE. On another UNO board, I have a GSM shield and another XBEE board.

The fiov3 is supposed to sample data from the sensor, send it through the xbee. The receiving XBEE will then receive and pass the data to the UNO. The UNo then activates the GSM shield on condition.

However my resulting output on the UNO is as shown :

The data received is corrupted.

CODE ON UNO.

XBee_Serial_Passthrough.ino

Set up a software serial port to pass data between an XBee Shield

and the serial monitor.

Hardware Hookup:

The XBee Shield makes all of the connections you ll need

between Arduino and XBee. If you have the shield make

sure the SWITCH IS IN THE DLINE POSITION. That will connect

the XBee s DOUT and DIN pins to Arduino pins 2 and 3.

// We ll use SoftwareSerial to communicate with the XBee:

include

// XBee s DOUT TX is connected to pin 2 Arduino s Software RX

// XBee s DIN RX is connected to pin 3 Arduino s Software TX

SoftwareSerial XBee 2, 3 ; // RX, TX

void setup

// Set up both ports at 9600 baud. This value is most important

// for the XBee. Make sure the baud rate matches the config

// setting of your XBee.

// If data comes in from serial monitor, send it out to XBee

// Serial1.println Hello. ;

printAccel ;

//if Serial1.available

// Serial.write Serial1.read ;

void printAccel

// Only read from the accelerometer if the accel interrupts,

// which means that new data is ready.

if digitalRead INT1XM

// Use the readAccel function to get new data from the accel.

// After calling this function, new values will be stored in

// the ax, ay, and az variables.

dof.readAccel ;

Serial.print A: ;

// Using the calcAccel helper function, we can get the

// accelerometer readings in g s.

Serial.print dof.calcAccel dof.ax ;

Any idea how to mitigate this would be greatly appreciated.
