Compatibility and Risks of Using VL53L3CX Library to Drive VL53L1 Sensor

Hello ST team,

I am using the full API for the VL53L1 TOF sensor, and I noticed that there are two versions of the full library available. One library (en.STSW-IMG015 VL53L3CX_BareDriver_1.2.10) is named vl53lx_api.c, and the other library (STSW-IMG019 VL53L1CB_BareDriver_6.6.18.2652) is named vl53l1_api.c. My understanding is that the library with "vl53lx" in the name should be a universal library that works with all TOF sensors, right? Both of these libraries seem to work with the VL53L1 TOF sensor. Our product aims to be compatible with both the VL53L3 and VL53L1 sensors while saving Flash space. Is there any risk in using the en.STSW-IMG015 VL53L3CX_BareDriver_1.2.10 library to drive the VL53L1 sensor?

Thank you in advance for your reply.

Hello

Using the SW packages of one device with another one may work.
Anyhow, tests are done using a combination of SW+HW and that's what ST is selling.
