i2c-slave

Rust project for the SparkFun ProMini 5v that implements i2c slave. Master complementary repo is here.

I'm flashing it via USB programmer and serial interface for it works for me with 4800 baud in serial monitor and 9600 on arduino board.

RAVEDUDE_PORT is configure with direnv .envrc file

Build Instructions

• Specify RAVEDUDE_PORT in .envrc if direnv is used. If you on linux with nix, change env var in flake.nix.

• Install prerequisites as described in the avr-hal README (avr-gcc, avr-libc, avrdude, ravedude).

• Run cargo build to build the firmware.

• Run cargo run to flash the firmware to a connected board. If ravedude fails to detect your board, check its documentation at https://crates.io/crates/ravedude.

• ravedude will open a console session after flashing where you can interact with the UART console of your board.
