How to use Rust on Arduino (Windows Rust)

#rust #arduino #embedded #systems

1 - Install Rust nightly compiler:

rustup toolchain install nightly

2 - Install Scoop via PowerShell:

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser irm get.scoop.sh | iex

3 - Install avr-gcc and avrdude using Scoop:

scoop install avr-gcc scoop install avrdude

4 - Install ravedude for flashing the microcontroller:

cargo +stable install ravedude

5 - Create a new project using cargo-generate:

cargo install cargo-generate cargo generate --git https://github.com/Rahix/avr-hal-template.git

6 - Navigate into the project directory and open the folder in your preferred code editor.

7 - Edit the main.rs file to include your desired program.

main.rs

#![no_std]
#![no_main]

use panic_halt as _;
use arduino_uno::prelude::*;

#[arduino_uno::entry]
fn main() -> ! {
    let dp = arduino_uno::Peripherals::take().unwrap();
    let mut pins = arduino_uno::Pins::new(dp.PORTB, dp.PORTC, dp.PORTD);
    let mut led = pins.d13.into_output(&mut pins.ddr);
    loop {
        led.toggle().void_unwrap();
        arduino_uno::delay_ms(1000);
        //Or Your Other Code Here
    }
}

Cargo.toml
[dependencies] arduino_uno = "0.2"

8 - Build the project:

cargo build

9 - Connect your Arduino board to your computer via USB.

10 - Set the serial com port for ravedude (replace COMx with the actual port number):

$env:RAVEDUDE_PORT="COMx"

11 - Build and flash the program into the Arduino:

cargo run

12 - After these steps, the Arduino should execute the program as intended.
