BME280MeasureAll()

BME280Status BME280MeasureAll

(

BME280Data *

data

)

Measures temperature, pressure, and humidity.

If you only need a single measurement channel, take all measurements and only take the needed measurement. Internally all channels need to be measured to get the value of a single channel.

Parameters

data

Returns

Status code

BME280MeasureTemperature()

uint8_t BME280MeasureTemperature	(	uint8_t *	data,
		Metadata	meta,
		uint32_t	idx
	)

BME280 sensor library function.

All three measurements (temperature, pressure, humidity) are measured and appropriate calibration are applied. Data gets encoded into a serialized measurement.

Parameters

data	Buffer to store measurement
ts	System time of measurement
idx	Sensor index

Returns

Length of measurement
