In the guide to using the VL53L5CX multizone Time-of-Flight ranging sensor it's described that for periodic temperature compensation the function vl53l5cx_set_VHV_repeat_count has to be called.I can't find the function in any header or c file.

I was using the sensor until now on an Raspberry Pi with direct access to the I2C bus without problems.Now I use an FT260 USB-I2C interface to communicate to the sensor from a PC via USB. In principle the communication is working, e.g. vl53l5cx_is_al...

I worked with a single VL53L5CX under Linux without problems. Now I wan't to have at least two sensors running in parallel connected to the same I2C bus. So I followed the documentation and first set LPn for the sensor which should keep its address (...

I just started working with VL53L5CX but can't find details on the commands/registers. I had a look to the example code and can use it but I can only guess what the different settings send via i2c to the firmware will do. I also studied the different...

Solved!Looking to the recorded data on the oscilloscope I saw that sometimes a byte was missing in the write sequence. Digging into the code I found the place responsible for this. Now it's working as expected.

When I see it right only WrByte and RdByte is called just before the first poll. So only short writes and reads are done.But what I meanwhile found out is, with lower clock speed (10 kHz instead of 100 kHz) the first poll works. But then the next fai...

Found it by myself. The sensor is really sensitive to changing the address. When I first set power enable to low and back again to high in order to have a powercycle everything works fine.

Ok, the signal is now available. The internal pull-up was not activated.

I just wrote a simple ranging test based on the examples. Two questions came up.The status for the measurement in each cell is either 5 or 255. According to what I read 255 means the value is not correct/uncertain e.g. because it's looking to empty s...
