This template builds a firmware for a split keyboard that has:
- Bluetooth host communication (using the left half)
- nRF52840 MCU on both halves (tested with nice!nano v2)
Note that memory.x contains values that correspond to an nRF52840 that has softdevice S140 6.1.1.
If your MCU has a different softdevice on it, you may need to change these values.
See the nrf-softdevice repo for more details.
This template assumes that you have rustup and cargo available in your $PATH, and that you have the latest nightly Rust toolchain.
Since this keyboard uses an nRF52840, we need to add the thumbv7em-none-eabihf target to our rust toolchain.
rustup target add thumbv7em-none-eabihfThe following instructions are specific to this MCU (nRF52840).
Note that .cargo/config.toml specifies thumbv7em-none-eabihf as our build target.
If you have a probe, make sure you install probe-run.
To build and flash the left half, call cargo run with the required features (specified in the Cargo.toml).
cargo run --bin left --release --features "rumcake/split-central rumcake/bluetooth rumcake/usb"Similarly with the right side:
cargo run --bin right --release --features "rumcake/split-peripheral"No instructions yet. Converting the binary to a UF2 and flashing that to the MCU doesn't seem to work.
