#PARALLELS NETWORK INITIALIZATION FAILED SOFTWARE#
I am programming a ATMEGA32 16PU micro-controller with usbtiny programmer ( AVR Pocket programmer by sparkfun), using winavr software from scourforge and also its appropriate driver. I am a newbie in micro-controller programming and so much like to learn up this technology.
