VL53L7CX Some zones not updated fast enough
We are trying to use a VL53L7CX sensor for a people counting application, but some zones won't change fast enough after a person passes through the detection field, even after a long time like 2-3 seconds. I tried resetting the sensor after each rang...
VL53L1CB Communication not working.
Hi,I am having an issue with the VL53L1CB TOF sensor where I cannot communicate with the sensor via I2C. I have everything configured correctly as far as I can tell but the API is returning status error -13. I am testing with a L476 nucleo and the SA...

Resolved! How to do the Crosstalk compensation for VL53L1X with VL53L1X ULD
I use a glass for our VL53L1X sensor. But we found there is a crosstalk problem and have to use crosstalk compensation. We use VL53L1X ULD for our device. There are three functions about crosstalk.int8_t VL53L1X_CalibrateXtalk(uint16_t dev, uint16_t...
Why does VL53L4CD hold SDA line low after requesting index 0x0110?
I've been implementing the platform functions for the VL53L4CD ULD. I have used and I2C library that I have been using for many years to interface many I2C devices such as EEPROM, rheostats and Vishay proximity sensors with no issue. I started by tes...
