emulator
========

to run emulator you need <https://www.raylib.com/> installed.
then `cd src && ./run_emulator.sh`.


hardware
========

to compile firmware use <https://platformio.org/>.
you need to create python venv or something, and then `pio run` will create firmware file.

schematic is in diagram.json, use <https://wokwi.com/> to display.
most of the stuff you can also see in platformio.ini, other than that connect button from pin 4 to ground.
