Drogue IoT BME680 Sensor driver

CI crates.io docs.rs Matrix

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

This crate helps to interface with the sensor. Offering general purpose access to the sensor, as well as a more opinionated controller logic, simplifying the process of taking measurements.

More information

Simple example

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

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

  let mut controller = Bme680Controller::new(
    bme680,
    delay,
    Configuration::standard(),
    StaticProvider(25),,  // fixed 25 degrees Celsius as ambient temperature
  ).unwrap();

  loop {
    let result = controller.measure_default().unwrap();
    log::info!("Measured: {:?}", result);
  }
}

BSEC

This crate can work together with the Bosch Sensortec Environmental Cluster (BSEC) library.

However, as the BSEC library is not open source, this crate does not include any dependencies, headers or other related artifacts of it. The BSEC interface is part of drogue-bsec.

Run unit tests

You can run the unit tests on simple host machine using:

cargo test --features env_logging test

Run examples

Run with (STM32F411):

cargo embed --release --features stm32f4xx --target thumbv7em-none-eabihf --example simple

Run with (STM32F723):

cargo embed --release --features stm32f7xx --target thumbv7em-none-eabihf --example simple

Dump data

You can enable logging of raw data, by enabling the feature dump, using --features dump. Note that this requires a logging implementation, such as rtt-logger. Note that this may have a huge negative impact on performance.
