Crate t67xx

A driver for Telaire T67XX CO2 sensor modules (tested on T6713).

Example

use linux_embedded_hal as hal;
use device_driver::ll::LowLevelDevice;
use t67xx::{AbcLogic, T67xxInterface, T67xxLL};

fn main() {
  let i2c = hal::I2cdev::new("/dev/i2c-1").unwrap();
  let delay = hal::Delay {};

  // Interface
  let t67xx_int = T67xxInterface::new(i2c, delay, None);
  // Low-level device
  let mut t67xx = T67xxLL::new(t67xx_int);

  // Enable ABC logic (usually enabled by default)
  t67xx.registers().abc_logic().write(|w| w.abc_logic(AbcLogic::Enabled));

  let status = t67xx.registers().status().read().unwrap();
  println!("{:?}", status);
  let ppm = t67xx.registers().gas_ppm().read().unwrap().gas_ppm();
  println!("CO2: {}ppm", ppm);
}
