There are currently no crates here for nRF54 parts. Pull requests are welcome. In the meantime, we recommend the embassy-nrf crate for this purpose. In spite of its name embassy-nrf also supplies a normal embedded-hal style interface.

Development

Be sure to copy and edit the Cargo.example.toml file to Cargo.toml. The file will require editing dependent on the target you wish to work with and contains some further instructions. Similarly, check out the .vscode/settings.json file when used in the context of Visual Studio Code. By default, all of these files are configured to work with the nRF52840 target.
