Keysight Bench Power Supply
You would think that for $1100 they could throw in a $2 switch.   That Jameco supply looks like it'll work fine.    I don't put a lot of trust into highly accurate...

Keysight Bench Power Supply
Brushless servo motor drive amplifiers.  I'm currently working on one that'll be using 110, but the power rails (as opposed to the bias rails) will be exactly 100V.   S...

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...

AVRISP MKII Availability
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...

AVRISP MKII Availability
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...

C code meets assembler - And falls down
Incidentally, Skeeve got it right some time ago, and I didn't give suitable credit. The other AVR is doing time-sensitive stuff. S.
