# 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.
## Usage
You will require the `thumbv7em-none-eabihf` target installed. To build one of these examples:
```console
$ 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.
