Crate arduino_hal

arduino-hal

Common HAL (hardware abstraction layer) for Arduino boards.

Note: This version of the documentation was built for Arduino Uno. This means that only items which are available for this board are visible. If you are using a different board, try building the documentation locally with

cargo doc --open

in your project (where arduino-hal is included with the feature-flag for your board).

Usage

For setting up a new project, the avr-hal-template is the recommended baseline. Applications should be built ontop of the following skeleton:

#![no_std]
#![no_main]

use panic_halt as _;

#[arduino_hal::entry]
fn main() -> ! {
    let dp = arduino_hal::Peripherals::take().unwrap();
    let pins = arduino_hal::pins!(dp);

    loop { }
}

For examples, please check the avr-hal examples: https://github.com/Rahix/avr-hal/tree/main/examples
