[QUOTE = mikroel; 3469662] Я кратко проверил вашу печатную плату и у меня есть один вопрос?

где 22pF подключен, одна сторона подключена к OSC 7,37 МГц, а другая сторона конденсаторов в воздухе? [/ QUOTE]
everything is good the second side on gnd

Hi, thanks for your help but in adaptation group "Axxx" there are not these channels :/ It's like a puzzle

I have not usbasp, i have old stk500 program interface. This interface has not 5v to supply atmega.

Then you can even reduce the cost of your scheme, throw away 2x9637 + 7812 = comparator lm339

I certainly don't understand how I could reduce the cost. but the goal is not to reduce costs, it is to have a 100% operational interface.

I'm not a vagcom expert, I had an interface like the one in the attached image, it broke down and I used the gal coming from this interface for mine. But when I tested it on an audi a3 2006 year, the interface doesn't erase faults. I had the doubt if the scheme was the right one.

Honestly, I stumbled what you want, you wipe out your schemes and boards, then write that you don't even have a normal GAL and programmers, sorry, I don't understand you, can anyone else understand and help

Yes ....is made and tested in a audi a3 . I don't have a gal programmer yet, so I used the old one.
The result is that after making an autoscan and finding several faults, the interface does not erase them, for this , i doubt if the scheme was correct.
Greetings and thank you for taking the time to answer.
