I'm really new with microcontrollers so please bear with me if I ask really stupid questions.
Nick, the work you did sounds great and since I have a Butterfly, I was thinking to give it a try. One question though: using your Arduino-like modifications, can I still use the serial cable I regularly use to program my Butterfly? Or do I need a parallel one (of which I had one when I fixed the 0x940c error but I misplaced it somehow).
BTW, thanks Smiley for your posts on avrfreaks, they helped me a lot to fix my Butterfly when I thought it was dead for good with the 0x940c error.
Thanks for your work and for reading.
