Pimoroni Unicorn

Rust implementation of the pimoroni unicorn devices.

Current support is focused on the galactic unicorn with embassy.

There is a basic working version of the galactic unicorn with the rp_hal crate.

Current Features

Galactic Unicorn

• Display
• Buttons
• Speaker
• Extensions

Unicorn Graphics

Holds a buffer of the led matrix 2d array used by the display. Benefits for using this library include:

• Hold multiple buffers of what can possibly be on the display
• Easily update the actual display buffer without loops
• Run comparisons against what is in the buffer, such as if it is colored or the same color as something else at a given pixel
• Support for the embedded graphics crate

Examples

Examples can be found within each respective folder of how to make use of the library and the unicorn graphics library.

Running examples

Install required dependencies.

rustup target add thumbv6m-none-eabi
cargo install elf2uf2-rs
cargo install probe-rs --features cli

You may need Rust nightly if running the embassy examples. Run the above command again after running rustup install nightly.

Change directory to the sample's base directory.

For example:

cd galactic-unicorn-rp/

Run the example

For example:

cargo run --release --example scrolling_text

Make sure your Pico is in boostel mode for this to succeed.
