Struct AsyncBme680

pub struct AsyncBme680<I2C, D> { /* private fields */ }

Available on crate feature embedded-hal-async only.

Asynchronous BME680 sensor driver.

This struct is similar to the Bme680 type, except that it uses the embedded_hal_async crate’s I2c and Delay traits, rather than the embedded_hal versions of those traits.

Notes

The AsyncBme680::new constructor is not asynchronous, and therefore — unlike the synchronous Bme680::new — it does not initialize the sensor. Instead, the sensor must be initialized using the AsyncBme680::initialize method before reading sensor data. Otherwise, the AsyncBme680::measure method will return BmeError::Uninitialized.

Implementations

impl<I2C, D> AsyncBme680<I2C, D>

where I2C: I2c<SevenBitAddress>, D: DelayNs,

pub fn new( i2c_interface: I2C, device_address: DeviceAddress, delayer: D, ambient_temperature: i32, ) -> Self

Creates a new instance of the Sensor

Arguments

• delayer - Used to wait for the triggered measurement to finish
• ambient_temperature - Needed to calculate the heater target temperature

Notes

This constructor is not asynchronous, and therefore — unlike the synchronous Bme680::new — it does not initialize the sensor. Instead, the sensor must be initialized using the AsyncBme680::initialize method before reading sensor data. Otherwise, the AsyncBme680::measure method will return BmeError::Uninitialized.

pub async fn initialize( &mut self, sensor_config: &Configuration, ) -> Result<(), BmeError<I2C>>

pub async fn put_to_sleep(&mut self) -> Result<(), BmeError<I2C>>

pub fn into_inner(self) -> I2C

Returns the wrapped i2c interface

pub async fn set_configuration( &mut self, config: &Configuration, ) -> Result<(), BmeError<I2C>>

pub async fn measure(&mut self) -> Result<MeasurmentData, BmeError<I2C>>

Trigger a new measurement.

Errors

If no new data is generated in 5 tries a Timeout error is returned.

pub fn get_calibration_data(&self) -> Result<&CalibrationData, BmeError<I2C>>
