RC Debounce problem
Notice that those hysteresis curves that Lee posted show hysteresis on the scale of a few MILLIVOLTS, That is surely a mistake in the graph labels. If you compare the VIL/VIH...

ATTINY84 freezes
The AT is running at 8MHz  Isn't 8MHz too fast at 1.8V? Or even at 2.5V.   The datasheet has this on the front page: • Speed Grade – ATtiny24V/44V/84V • 0 – 4 MHz @ 1.8...

Relay control circuit-strange behavior
Your footswitch in on the reset pin. You can't use that as a general purpose I/O unless you have disabled the reset with the RSTDISBL fuse. But if you do that, then you can't...

Prescaller for 128K internal on Tiny24
Glad you figured it out. I'll comment on a few things in the code. First, you don't need to specify the path to the .inc file. .include will find the correct file. .equ...
