Hi all,
I have an avr dragon connected via ISP to an atmega32a mounted in a breadboard. For now I don't pretend more than to read the device id. I'm using AVRStudio 6.0 to comunicate with the microcontroller and I have a strange problem. The first time I try to read the device id all goes fine but the next time it fails...I have to switch off/on the supply to read again the ID but only for one time...
I have a 1uF bypass capacitors between both Vcc-GND and Avcc-GND and the ISP cable lenght is very short, about 100mm.
I don't know what to do to solve the problem, if someone has any advice I'll appreciate it very much.
Cheers,
Francesco
