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 theonboard 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 thethumbv7em-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 theBoard::init() function.
