Rust driver for Rainbox HAT

This repository contains an unofficial Rust driver library for Rainbow HAT, for use with Raspberry Pi OS on your Raspberry Pi.
For the official Python driver see: https://github.com/pimoroni/rainbow-hat.
For the official AndroidThings driver see: https://github.com/androidthings/contrib-drivers/tree/master/rainbowhat.

This library depends on https://github.com/golemparts/rppal for access to the Raspberry Pi peripherals.

Current periferials supported: | Periferial | Supported | Structs | |----------------------------------------|-----------|----------------------------------------| | Multicolour LEDs | | | | Four 14-segment alphanumeric displays | X | rainbowhatrs::alphanum4::Alphanum4 | | Three capacitive touch buttons | X | rainbowhatrs::touch::Buttons | | Temperature and pressure sensor | | | | Blue, green and red LEDs | X | rainbowhatrs::lights::Lights | | Piezo buzzer | | |

Usage

Add a dependency for rainbow-hat-rs to your Cargo.toml.

toml [dependencies] rainbow-hat-rs = "0.1.0"

Call new() on any of the peripherals to construct a new instance.

```rust use rainbowhatrs::lights::Lights; use rainbowhatrs::alphanum4::Alphanum4; use rainbowhatrs::touch::Buttons;

let lights = Lights::new()?; let buttons = Buttons::new()?; let alphanum = Alphanum4::new()?; ```

Examples

See folder examples.

Lights

```rust let lights = Lights::new()?;

// Turn on red and green lights lights.rgb(true, true, false);

// Turn off red light lights.red.off()

// Turn on blue light lights.blue.on()

// Toggle green light lights.green.toggle() ```

Buttons

```rust let buttons = Buttons::new()?;

// Identify if button A is pressed if buttons.a.is_pressed() { println!("Button A touched!"); } ```

Display

```rust let mut alphanum = Alphanum4::new()?;

// Print a message on the display alphanum.print_str("1234", false); alphanum.show()?; ```

Caution

Always be careful when working with the Raspberry Pi's peripherals, especially if you attach any external components to the GPIO pins. Improper use can lead to permanent damage.
