For many years, I have used a few batch files to program ATTiny44 chips for a client. Every now and then he asks for 50 or 100, and I program them and forget about them for a few months.
The batch files I've always used use the SKT500.EXE command, which I have in the same directory. Now, suddenly, the SKT500.EXE reports that it is unable to connect via USB. Could be that my trusty AVRISP MK2 is broken, I suppose, but I'm inclined to believe something has changed driver-wise. Is there a way I could use AVRDude to check out the functionallity of the AVRISP?
