jetsongpio

A Rust library that enables the use of Jetson's GPIOs.

This is the Rust implementation of the Python library for controlling GPIO pins on NVIDIA Jetson devices.

Features

• GPIO character device API (not sysfs)
• Board, BCM, Tegra SOC, and CVM pin numbering modes
• Input and output modes
• Pin cleanup

Example

use jetsongpio::{GPIO, Level, Mode, gpio::Direction};
use std::thread;
use std::time::Duration;

fn main() {
    let mut gpio = GPIO::new();
    gpio.setmode(Mode::BOARD).unwrap();

    // Setup pin as output with initial LOW value
    gpio.setup(vec![29], Direction::OUT, Some(Level::LOW)).unwrap();

    loop {
        // Set HIGH
        gpio.output(vec![29], vec![Level::HIGH]).unwrap();
        thread::sleep(Duration::from_secs(1));

        // Set LOW
        gpio.output(vec![29], vec![Level::LOW]).unwrap();
        thread::sleep(Duration::from_secs(1));
    }

    // Cleanup
    gpio.cleanup(None).unwrap();
}

Requirements

• NVIDIA Jetson platform (Jetson Nano, Jetson TX1/TX2, Jetson Xavier, Jetson Orin, etc.)
• Linux kernel with GPIO character device support
• Access to /dev/gpiochip0 (requires proper permissions or root user)
