Implementations

impl<I: Interface> Device<I>

pub fn initialize(interface: I) -> Result<Self, Error>

Initialization.

Reads the chip-id of the sensor which is the first step to verify the sensor and also calibrates the sensor.

pub fn soft_reset(&mut self) -> Result<(), Error>

Triggers a soft-resets of the sensor.

pub fn set_config(&mut self, conf: DeviceConfig) -> Result<(), Error>

Used to set the oversampling, filter and odr configuration.

pub fn get_conf(&mut self, conf: &mut DeviceConfig) -> Result<(), Error>

Used to get the oversampling, filter and odr configurations.

pub fn set_op_mode(&mut self, op_mode: OperationMode) -> Result<(), Error>

Used to set the operation mode of the sensor.

pub fn get_op_mode(&mut self) -> Result<OperationMode, Error>

Used to get the operation mode of the sensor.

pub fn get_measure_duration(&mut self, op_mode: OperationMode) -> u32

Used to get the remaining duration that can be used for heating.

pub fn get_data( &mut self, op_mode: u8, data: *mut SensorData, n_data: &mut u8, ) -> Result<(), Error>

Reads the pressure, temperature humidity and gas data from the sensor, compensates the data and store it in the SensorData structure instance passed by the user.

TODO refactor and make safer.

pub fn set_gas_heater_conf( &mut self, op_mode: OperationMode, conf: GasHeaterConfig, ) -> Result<(), Error>

Used to set the gas configuration of the sensor.

pub fn get_gas_heater_conf( &mut self, config: GasHeaterConfig, ) -> Result<(), Error>

Used to get the gas configuration of the sensor.
