 ## Firmware/Programming
-Currently, there are two different implementations of the
-firmware. The older one which is written in C and is not finished, and
-the newer one which is in an early but functioning state and written
-in Rust.
-
-Note that mostly due to the display, the supply voltage after the LDO
-regulator is 3.3V.
-
-### The Rust Firmware
 To flash the firmware, connect the ICSP pins of the board to the
-programmer and inside the `firmware/rust/` directory run `cargo make
+programmer and inside the `firmware` directory simply run `cargo make
 --profile release all`. This compiles the firmware with the release
 profile, burns the fuses, writes the default configuration values to
 the EEPROM and flashes the firmware.
