Struct ReadMeasurement 

Source 
pub struct ReadMeasurement {}
Expand description

Reads the sensor output. The measurement data can only be read out once per signal update interval as the buffer is emptied upon read-out. If no data is available in the buffer, the sensor returns a NACK. To avoid a NACK response, GetDataReady can be issued to check data status. The I2C master can abort the read transfer with a NACK followed by a STOP condition after any data byte if the user is not interested in subsequent data.

May be used while measuring.

Out: Measurement

Execution time (ms): 1
