AVRISP-II and AVRDUDE
Posted: Thu Mar 12, 2015 2:44 pm
I use an AVRISP-II programmer for flashing Atmel AVR processors, but I couldn't use it with eepe as Atmel Studio 6.0 loads its own drivers that don't work with AVRDUDE.
I just found this site however:

and, having followed the instructions, I now have the AVRISP-II working with AVRDUDE and eepe.
There is one other problem with using the AVRISP-II, the same problem I have with my STK500. The signal drivers cannot cope with the capacitors that load the reset and signal lines. I solved this for the STK500 by buffering the programmer output signals with some 74AC devices. These provide plenty of drive and I use this with both the STK500 and the AVRISP-II.
