+# [pimoroni-plasma-2040] - Board Support for the [Pimoroni Plasma 2040]
+
+You should include this crate if you are writing code that you want to run on
+a [Pimoroni Plasma 2040] - Swathe everything in rainbows with this all-in-one, USB-C powered controller for WS2812/Neopixel and APA102/Dotstar addressable LED strip.
+
+This crate includes the [rp2040-hal], but also configures each pin of the
+RP2040 chip according to how it is connected up on the Pimoroni Plasma 2040.
+
+[Pimoroni Plasma 2040]: https://shop.pimoroni.com/products/plasma-2040
+[pimoroni-plasma-2040]: https://github.com/rp-rs/rp-hal/tree/main/boards/pimoroni-plasma-2040
+[rp2040-hal]: https://github.com/rp-rs/rp-hal/tree/main/rp2040-hal
+[Raspberry Silicon RP2040]: https://www.raspberrypi.org/products/rp2040/
+
+## Using
+
+To use this crate, your `Cargo.toml` file should contain:
+
+```toml
+pimoroni-plasma-2040 = "0.1.0"
+```
+
+In your program, you will need to call `pimoroni_plasma_2040::Pins::new` to create
+a new `Pins` structure. This will set up all the GPIOs for any on-board
+devices. See the [examples](./examples) folder for more details.
+
+## Examples
+
+### General Instructions
+
+To compile an example, clone the _rp-hal_ repository and run:
+
+```console
+rp-hal/boards/pimoroni-plasma-2040 $ 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_ 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/pimoroni-plasma-2040 $ 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.
+
+### [pimoroni_plasma_2040_blinky](./examples/pimoroni_plasma_2040_blinky.rs)
+
+Flashes the Plasma 2040's three on-board LEDs in sequence.
+
+### [pimoroni_plasma_2040_ws2812_led](./examples/pimoroni_plasma_2040_ws2812_led.rs)
+
+Drives 3 WS2812 LEDs connected directly to the Pimoroni Plasma 2040 via its onboard terminal block.
+
+## Contributing

+be learn, inspire, and create. Any contributions you make are **greatly
+appreciated**.
