BME280_ReadAllForce_F()

int8_t BME280_ReadAllForce_F	(	BME280_t *	Dev,
		BME280_DataF_t *	Data
	)

Function forces single measure and returns all data as floats.

Note

Sensor must be in BME280_SLEEPMODE to force a single measurement.

Function reads sensor's configuration to check conditions and calculate max. delay time required for measure cycle. Then sends command to force single measurement and calls used-defined delay function. When delay function returns ir reads all adc values from sensor, converts them into single variables and compensate with use BME280_calibration_data. Compensated values are then converted into BME280_DataF_t structure.

Parameters

[in]	*Dev	pointer to sensor's BME280_t structure
[out]	*Data	pointer to structure where result will be stored

Returns

BME280_OK success

BME280_PARAM_ERR wrong parameter passed

BME280_INTERFACE_ERR user defined read/write function returned non-zero value

BME280_NO_INIT_ERR sensor was not initialized before

BME280_CONDITION_ERR sensor is not in BME280_SLEEPMODE

BME280_BUSY_ERR sensor is busy so cannot proceed

BME280_ReadHumForce_F()

int8_t BME280_ReadHumForce_F	(	BME280_t *	Dev,
		float *	Hum
	)

Function forces single measure and returns humidity as floats (forced mode)

Note

Sensor must be in BME280_SLEEPMODE to force a single measurement.

Function reads sensor's configuration to check conditions and calculate max. delay time required for measure cycle. Then sends command to force single measurement and calls used-defined delay function. When delay function returns ir reads temperature and humidity related adc values from sensor, converts them into single variables and compensate with use BME280_calibration_data. Compensated values are then converted into float.

Parameters

[in]	*Dev	pointer to sensor's BME280_t structure
[out]	*Hum	pointer to variable where humidity will be stored

Returns

BME280_OK success

BME280_PARAM_ERR wrong parameter passed

BME280_INTERFACE_ERR user defined read/write function returned non-zero value

BME280_ReadPressForce_F()

int8_t BME280_ReadPressForce_F	(	BME280_t *	Dev,
