Crate drogue_bme680

drogue-bme680 is a crate to interface with the BME680 sensor.

The BME680 sensor is a "low power gas, pressure, temperature & humidity sensor" from Bosch Sensortec.

The crate provides two layers of access to the sensor. Bme680Sensor provides general purpose access to the sensor. While Bme680Controller takes care of most steps of the default sensor workflow for taking measurements, providing a simpler, more user-friendly interface.

Example

use drogue_bme680::*;

fn main() -> ! {
  let i2c = mock::blocking_i2c();
  let mut timer = mock::create_timer();

  let bme680 = Bme680Sensor::from(i2c, Address::Secondary).unwrap();

  let mut controller = Bme680Controller::new(
    bme680,
    &mut timer,
    Configuration::standard(),
    || 25,  // fixed 25 degrees Celsius ambient temperature
  ).unwrap();
   
  loop {
    let result = controller.measure_default().unwrap();
    log::info!("Measured: {:?}", result);
  }
}

Known limitations

• Currently, the crate only provide access to the sensor using I2C.
