... The response to this command is the Standard Response byte, returned on the next SPI shift. During calibration, device communications are suspended. 3.3.3 0x03 - Drift Compensate 0x03 causes the sensor to perform incremental drift compensation. This command must be given periodically in order to allow the sensor to compensate for drift. The more 7 QT511-ISSG R6.01/1005 ...
