About temperature calibration of VL53L1X

KArai.2 · ‎2023-07-26

Hello,

I am developing a system using VL53L1X.
I have read UM2510 (A guide to using the VL53L1X ultra lite driver).

This library implements the function called "StartTemperatureUpdate".
The description for this function states, "This function performs the temperature calibration."
The function declaration is written as:

VL53L1X_ERROR VL53L1X_StartTemperatureUpdate(uint16_t dev);

I'm curious as to why this function doesn't require the actual temperature as an input.
The mechanism of temperature calibration, please let me know.
It would be helpful if you could introduce related documents and URLs for reference.

Best Regards.

Hello,

Everything is done inside the sensor firmware, user has nothing to do.

Everything is embedded, it is a transparent operation that doesn't require information from the host.

Hello, Anne BIGOT-san,

Thank you for your reply.

Can I assume that the VL53L1X has a built-in temperature sensor (or something similar)?

Best Regards.

Do we have access to the temperature sensor inside the device? Could we potentially poll what the device's temperature is?
