Board Support Package for the Nordic nRF52840-DK

This crate is a Board Support Package (BSP). It wraps the HAL crate (nrf52840-hal) for the on-board nRF52840, and provides high level wrappers for the onboard features:

  • 4 on-board LEDs
  • 4 on-board buttons

This BSP assumes you are not using a bootloader running in non-secure mode.


You will require the thumbv7em-none-eabihf target installed. To build one of these examples:

$ rustup target add thumbv7em-none-eabihf
$ git clone https://github.com/nrf-rs/nrf52840-DK.git
$ cd nrf52840-DK
$ cargo build --target=thumbv7em-none-eabihf --example blinky

To use in your own application, add as a dependency and call the Board::init() function.


The docs for this crate can be found at https://docs.rs/nrf52840-dk-bsp. The manufacturer's documentation is available from https://infocenter.nordicsemi.com/pdf/nRF52840_DK_User_Guide_v1.4.1.pdf.
