OPT3101: Register settings related

hi,

 

Regarding the register "USE_XTALK_REG_ILLUM" setting. 0: Calibration value | 1: Register value, where is the difference between "Calibration value" and "Register value"?There is the same doubt about the setting of the register "USE_XTALK_REG_INT".

Best,

    Hi,

    This needs to be set to 1 and the calibration written into the register for the calibration to be applied. If a value of zero the device calibration value will be used, but this will not work correctly if not calibration is run on power up. Usually calibration is performed and value stores to be written into the register at each power up.

    Best,
