Detailed Description

read last measured data from sensor in normal mode

Note

USE_NORMAL_MODE in Library Configuration must be uncommented to use these functions

Function Documentation

BME280_ReadAllLast_F()

int8_t BME280_ReadAllLast_F	(	BME280_t *	Dev,
		BME280_DataF_t *	Data
	)

Function reads all measured data at once.

Note

Sensor must be in BME280_NORMALMODE to read last measured values.

Function 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_NORMALMODE

Here is the call graph for this function:

BME280_ReadHumLast_F()

int8_t BME280_ReadHumLast_F	(	BME280_t *	Dev,
		float *	Hum
	)

Function reads last measured humidity.

Note

Sensor must be in BME280_NORMALMODE to read last measured values.

Function reads temperature and humidity related adc values from sensor, converts them into single variables and compensate with use BME280_calibration_data. Compensated value is then converted into floating point value and stored in external variable

Parameters

[in]	*Dev	pointer to sensor's BME280_t structure
[out]	*Hum	pointer to variable where temperature 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_NORMALMODE

Here is the call graph for this function:

BME280_ReadPressLast_F()

int8_t BME280_ReadPressLast_F	(	BME280_t *	Dev,
		float *	Press
	)

Function reads last measured pressure.

Note

Sensor must be in BME280_NORMALMODE to read last measured values.

Function reads temperature and pressure related adc values from sensor, converts them into single variables and compensate with use BME280_calibration_data. Compensated value is then converted into floating point value and stored in external variable

Parameters

[in]	*Dev	pointer to sensor's BME280_t structure
[out]	*Press	pointer to variable where temperature 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_NORMALMODE

Here is the call graph for this function:

BME280_ReadTempLast_F()

int8_t BME280_ReadTempLast_F	(	BME280_t *	Dev,
		float *	Temp
	)
