raslib

Manage a Raspberry Pi device from Rust. GPIO ports and L298N motors controller

All tests are performed 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 has a really good way to create sockets.

Install

In your "Cargo.toml" file : toml [dependencies] raslib = "*" Check the current version on crates.io.

Examples

• Blink a led

  ```rust 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

  ```rust use raslib::l298n::L298n;

  fn forwardforever() -> Result<(), std::io::Error> { let mut motorleft = L298n::new(18, 15, 14); let mut motor_right = L298n::new(9, 7, 25);

  motor_left.forward()?;
  motor_right.forward()?;
  
  Ok(())
  

  } ``` Considering your connection are made this way: (from : alcalyn.github.io)

Server socket

Modified from the Rust docs example: ```rust use std::io::prelude::*; use std::net::TcpListener; use std::net::TcpStream;

fn server() { let server = TcpListener::bind(":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 with the raspi
    }
}

} ```
