rust-pca9685

The Rust pca9685 crate is for manipulating the Adafruit 16-Channel servo driver and other boards based on the PCA9685. I wrote this before I found i2c-pca9685 with nearly the identical interface. You should probably use that instead.

Example

extern crate pca9685;
extern crate i2cdev;

use pca9685::pwm::PWM;
use i2cdev::linux::{LinuxI2CError};

fn main() {
    match move_servo() {
        Ok(()) => println!("it worked!"),
        Err(err) => println!("uhoh: {}", err),
    }
}

fn move_servo() -> Result<(), LinuxI2CError> {
    let mut pwm = PWM::new("/dev/i2c-1", 0x40)?;
    pwm.set_pwm_freq(60.0)?;
    pwm.set_pwm(0, 0, 500)?;
    pwm.set_pwm(1, 0, 500)?;
    Ok(())
}
