…about a million more similar errors…

If you said “mike configured his microcontroller as an ATmega16 when he is obviously using an ATmega8” you are smarter than me.

So yes, at least 1 cause of these errors is specifing the right microcontroller. I edited my Makefile to use atmega8 instead of atmega16 and everything worked like a charm.

    Hey Mike,

    What are you going to be doing with the micro controller?

    My plan is to build strange and wonderful input devices. I’ve actually have a working prototype now – a mess of wires and buttons that acts like a USB keyboard.

    I was actually going to do a post about it finally working, but I wanted to get a photo of my fancy breadboard and I don’t have a working camera. I think I have the power cable to the old camera at your place somewhere.
