trying out microcontrollers

i did some work with the bitbox a long time ago, and i've been excited to try out building my own gadgets. i wanted to work with a 32 bit architecture, which may be overkill for my synth, but it would help with experience for future projects.

i picked up a Raspberry Pi Pico 2, which has nice getting started documentation, but i like doing things with the command line rather than VSCode, so i put together this little tutorial: https://codeberg.org/lowagner/pico-test.

i was getting a ERROR: Cannot determine the binary size, so cannot save the program only, try --all. when doing `picotool save`, but that's because `save` will download from the device, when i wanted to upload (using `load`). well, progress is progress. i have a blinking light on my desk for now.
