Struct bsec::bme::bme680::Bme680Sensor

pub struct Bme680Sensor<I2C, D> where
    I2C: Read + Write,
    D: DelayMs<u8>,  { /* fields omitted */ }

Implementation of the BmeSensor trait for the BME680 sensor.

For the gas resistance measurement, the last reading of the temperature sensor will be used as ambient temperature.

Example

use bme680::{Bme680, I2CAddress};
use bsec::bme::bme680::Bme680Sensor;
use linux_embedded_hal::{Delay, I2cdev};

let i2c = I2cdev::new("/dev/i2c")?;
let bme680 = Bme680::init(i2c, Delay {}, I2CAddress::Primary)?;
let sensor = Bme680Sensor::new(bme680, 20.);

Implementations

impl<I2C, D> Bme680Sensor<I2C, D> where
    I2C: Read + Write,
    D: DelayMs<u8>, 

pub fn new(
    bme680: Bme680<I2C, D>,
    initial_ambient_temperature_celsius: f32
) -> Self

Create a new instance reading measurement from bme680.

initial_ambient_temperature_celsius sets the ambient temperature for the first gas resistance reading. All subsequent readings use the respective last temperature reading.

Trait Implementations

impl<I2C, D> BmeSensor for Bme680Sensor<I2C, D> where
    D: DelayMs<u8>,
    I2C: Read + Write,
    <I2C as Read>::Error: Debug,
    <I2C as Write>::Error: Debug, 

type Error = Error<<I2C as Read>::Error, <I2C as Write>::Error>

Error type if an operation with the sensor fails.

fn start_measurement(
    &mut self,
    settings: &BmeSettingsHandle<'_>
) -> Result<Duration, Self::Error>

Starts a sensor measurement.

fn get_measurement(&mut self) -> Result<Vec<Input>, Self::Error>

Read a finished sensor measurement.
