There are no jumper on my programmer.
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 ?
