\subsection{Connecting to Programmer}
These notes may be redundant, need to double check.
When connecting, have a base setup that works as a sanity check.
It may be possible to blow out atmega328p pins if you leave attiny running, thne
plug in the cable back to front (i.e. pin 13 in 9).
You might need to reboot the arduino completely.
From Programmer Source code:
- Upload to arduino and power off
- Connect ATtiny10 as shown
- Power on and open the serial monitor
- If things are working so far you should
see "NVM enabled" and "ATtiny10/20/40 connected".
- Input one-letter commands via serial monitor:
This programmer is not foolproof, so establish a routine, and keep a working
model (pcb w/attiny) as a prototype to isolate what is broken.
