raslib

Raspberry PI library for Rust. GPIO controller, L298N motors, sockets and "i2clib" integrated

All tests are made on Raspberry PI 4B+ on Raspbian OS

Overview

• GPIO controller
• L298N motors controller (needs the GPIO controller)

NOTE there is no server socket generator because the Rust standard library already contains a really good way to create sockets
SEE here to create a server socket

Install

In your project Cargo.toml file, add the "raslib" dependency :

[dependencies]
raslib = { git = "https://github.com/antoninhrlt/raslib" }

And then, build your project : cargo build

Examples

• Blink a led

  use raslib;
  use raslib::gpio::Gpio;
  
  fn blink_led() -> Result<(), std::io::Error> {
      let led = Gpio::new(16)?;
      loop {
          led.write(raslib::HIGH)?;
          raslib::sleep(1000);
          
          led.write(raslib::LOW)?;
          raslib::sleep(1000);
      }
  }

• L298N motor

  use raslib::l298n::L298n;
  
  fn forward_forever() -> Result<(), std::io::Error> {
      let mut motor_left = L298n::new(18, 15, 14);
      let mut motor_right = L298n::new(9, 7, 25);
  
      motor_left.forward()?;
      motor_right.forward()?;
  
      Ok(())
  }

Server socket

From doc.rust-lang.org

use std::io::prelude::*;
use std::net::TcpListener;
use std::net::TcpStream;

fn server() {
    let server = TcpListener::bind("<raspi ip>:9000").unwrap();

    for stream in server.incoming() {
        let mut stream: TcpStream = stream.unwrap();

        let mut signal = [0; 1];
        loop {
            stream.read(&mut signal); 
            if signal[0] == 0 {
                break;
            }

            // does things
        }
    }
}
