# [pimoroni_badger2040] - Board Support for the [Pimoroni Badger2040]

You should include this crate if you are writing code that you want to run on
a [Pimoroni Badger2040] - a conference-style badge built around an e-paper
display and an rp2040

This crate includes the [rp2040-hal], but also configures each pin of the
RP2040 chip according to how it is connected up on the Badger2040.

## Using

To use this crate, your `Cargo.toml` file should contain:

```toml
pimoroni_badger2040 = "0.6.0"
```

In your program, you will need to call `pimoroni_badger2040::Board::take().unwrap()` to create
a new `Boards` structure. This will set up all the GPIOs for any on-board
devices and configure common clocks. See the [examples](./examples) folder for more details.

## Examples

### General Instructions

To compile an example, clone the _rp-hal-boards_ repository and run:

```console
rp-hal-boards/boards/pimoroni_badger2040 $ cargo build --release --example <name>
```

You will get an ELF file called
`./target/thumbv6m-none-eabi/release/examples/<name>`, where the `target`
folder is located at the top of the _rp-hal-boards_ repository checkout. Normally
you would also need to specify `--target=thumbv6m-none-eabi` but when
building examples from this git repository, that is set as the default.

If you want to convert the ELF file to a UF2 and automatically copy it to the
USB drive exported by the RP2040 bootloader, simply boot your board into
bootloader mode and run:

```console
rp-hal-boards/boards/pimoroni_badger2040 $ cargo run --release --example <name>
```

If you get an error about not being able to find `elf2uf2-rs`, try:

```console
$ cargo install elf2uf2-rs
```
then try repeating the `cargo run` command above.

### [badger_blinky](./examples/badger_blinky.rs)

Flashes the Badger2040's activity LED on and off.
