This is derived from the awesome work here and here
The original blogpost code still more-or-less works, but some library calls needed to be updated.
Also the dependencies are provided by Nix, so this should be relatively reproducible.
To build the code, all prerequisites are sourced via Nix, so just run nix-shell to get the correct environment
To run the code on an AVR chip, you will need the following:
- an AVR chip (currently only atmega168 is supported)
- an ISP (eg an Arduino with the "ArduinoISP" sketch flashed to it)
- an LED to confirm the pin is being "blinked" correctly
- a breadboard to connect all the components up (like eg https://medium.com/@srmq/using-arduino-board-as-isp-to-program-atmega328-ic-without-a-crystal-667ef0fccf4)
Connect the LED between pin 15 and GND, with a suitable protective resistor in series.
nix-shell
make # generates Julia AVR code and builds the hex file
make flash # flashes the chip (builds the hexfile if needed)
