This is my programmer: http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=130950244805&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 There is no documentation with it. My computer has not a parallel port, that's why I use a USBasp programmer. Previously, on an other computer, I was able to program a micro-controller with avrdude and a DAPA programmer I made myself. A USB programmer is more difficult to use because it has a micro-controller that contains a firmware that sometimes need to be updated. My product can't be updated easily because I must break the box to access to the programmer card. Also, I hope I am not doing a mistake when I link my programmer to the micro-controller. As you can see on the picture, the cable has a colored part. I consider that this is where the "1" pin is. Maybe it's wrong. Do you think it is correct ? _______________________________________________ AVR-chat mailing list AVR-chat@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-chat
