VL53L1CB calibration functions

Victor_Innovex · ‎2024-11-27

Hello ST team.

I am operating the VL53L1CB sensor with zephyrRTOS, I reach distances to four meters without problems, in addition to measure distance above them (eight meters top in ideal conditions), all this in ROI.
I am working with the manual UM2133 and I have doubts about the calibration, I have a crystal covers (bought by aliexpress) and I did the calibration proposed by the manual, it has some crosstalk interference, it works with intermediate accuracy and precision.
Do you have any manual that explains in more detail about the calibration (refSPAD, crosstalk, offset)? especially the point “6.2.6 Setting crosstalk calibration data” that makes in detail the parameters and how it affects the sensor.

The purpose is to improve accuracy and precision

Best regards
Thanks!

the best info on crosstalk is

It's short, but it references a couple longer, more in-depth documents.

Give that a read and see if it explains enough for you.
