It is always 0 to get the value of OUT_TEMP_L_A (0Ch), OUT_TEMP_H_A (0Dh).Before reading OUT_TEMP_L_A (0Ch), OUT_TEMP_H_A (0Dh), check the values of TEMP_CFG_REG_A (1Fh), CTRL_REG4_A (23h) and STATUS_REG_AUX_A (07h) as bellow:TEMP_CFG_REG_A (1Fh): 0x...

I use VL53L1X ultra lite driver.For example:The value written to ALGO__PART_TO_PART_RANGE_OFFSET_MM(0x001E) register is 0xFF24 when VL53L1X_SetOffset() is called with OffsetValue -55.The value got from ALGO__PART_TO_PART_RANGE_OFFSET_MM(0x001E) regis...

Host side is Freescale i.MX8MQ. The STMems_Android_Sensor_HAL_Input driver from ST's website is used on Android 9.No temperature sensor is implemented in the lsm303agr part of STMems_Android_Sensor_HAL_Input driver.I try to add some code in the lsm30...

Follow the above modification, the returned offset value is still incorrect.VL53L1X_ERROR VL53L1X_GetOffset(VL53L1_Dev_t dev, int16_t *offset) { VL53L1X_ERROR status = 0; uint16_t Temp; status = VL53L1_RdWord(&dev,ALGO__PART_TO_PART_RANGE_OFFSET...

From document, it says that RefSPAD and crosstalk calibrations have to be performed whenever the customer adds a protective cover glass on top of the VL53L1X module. So the VL53L1X ULD driver can solve the case that a protective cover glass is on top...

[lsm303agr] How to get temperature sensor value correctly?

[LSM303AGR] The compass does not work.

Is there calibration module in the STMems_Android_Sensor_HAL_Input package ?

The offset value to VL53L1X_SetOffset set is different from the one VL53L1X_GetOffset got from.

There is no RefSPAD calibration in VL53L1X ULD driver. How to peform RefSPAD calibration if VL53L1X ULD driver is used ?
