How to use TWI in atmega32A in assembler?
I beat my head against the AVR's TWI for awhile, and found this thread after a quick search.  Note that this thread is five years old, I'm just lighting it up again now....

I thought I'd throw a bone in here...   I built a six-channel quadrature encoder counter using seven AVRs awhile back (yep, seven on one board).  Six Tiny2313s and one...

Thanks! I looked, and found this: Which looks pretty close to what I want. All my boards have 6-pin ISP connectors (they're smaller!) and it...

Oh no. "The AVR Dragon sets a new standard for low-cost development tools". Except a) the MK II ISP was cheaper, at $39, and b) it came in a complete plastic enclosure, not a...

C code meets assembler - And falls down
Yay! OP here. I believe I have fixed it, although there's a few things I still don't quite understand. Anyhow, there were two interacting problems, which added to the confusion...

Incidentally, Skeeve got it right some time ago, and I didn't give suitable credit. The other AVR is doing time-sensitive stuff. S.

And just to add to the philosophical arguments, I'll throw in this hypothesis: The higher-level the language is, the easier it is to write really atrocious code. Laying down...

OP here again, if I'm still relevant... 8) 1st) Keep in mind the whole thing is a heavily edited version of the 'DualVirtualSerial' device from LUFA. I've whacked out one...
