# `nrf52840_blinky`
An RTIC blinky example intended for [nrf52840-dongle].
[nrf52840-dongle]: https://www.nordicsemi.com/Products/Development-hardware/nrf52840-dongle
## Dependencies
#### 1. `flip-link`:
```console
$ cargo install flip-link
```
#### 2. `probe-rs`:
``` console
$ # make sure to install v0.2.0 or later
$ cargo install probe-rs --features cli
```
## Run
The [nrf52840-dongle] needs to be connected to the computer via an SWD probe, like a [J-Link EDU Mini].
Then, run:
```
cargo run --release --bin blinky_timer
```
[J-Link EDU Mini]: https://www.segger.com/products/debug-probes/j-link/models/j-link-edu-mini/
