Resolved! TOF data varies every half hour
We have TOF data collected every half hour, but we are surprised by the results, as the TOF data is not consistent each time.

Resolved! VL53L0X mechanical sizing information
We are developing sensing device with using VL53L0X, we will use optical lens on top of VL53L0X for special sensing purpose then in order to optimize lens design with effecive sensing, we would like to know dimension of both sensor and emitting ch...
Using VL53l0x with DMA
I have an application that needs to use several VL53l0x ToF sensors. The measurements need to be fairly responsive to a slow moving object approaching the sensor; so something like taking readings at 10Hz would be reasonable. Having tried a quick pr...
Resolved! Init Failures on VL53L5, L7 and L8 due to long I2C writes
The most viewed and commented post on the Imaging page had to do with an Init failure on the multizone part. These parts have large I2C writes at the beginning, which is downloading the Firmware (on the L5 and L7) and downloading patch updates on the...
VB1940 Pinout
Hi ST Support.I am currently working with a camera module using VB1940. I could not find a detailed pinout or pin definition in the official documentation. I would greatly appreciate it if someone could help me with that.Thank you very much for your ...
Resolved! VL53L7CX - Resetting sensor(s) without power cycling after they have initialized with ULD init()
Hello, we have a system that consists of 12 VL53L7CX sensors each, on 4 different I2C busses and we are using an I2C address translators (LTC4316CDD) to address them all without needing to change their address dynamically. We are using ST's ULD (ultr...
Confusion on the VL53L1-SATEL registers
Hello, I am currently trying to write code for the I2C communication with the VL53L1-SATEL board. I was trying to confirm that the I2C was working by reading some registers mentioned in the VL53L1 Datasheet, those being 0xC0, 0xC1, 0xC2, 0x51, and 0x...
Resolved! Source available for STSW-IMG041 Device Code ?
Hi,I would like to know if the STSW-IMG041 code that is flashed into the device is available somewhere. My goal would be to use the same code but on a custom board to verify that the sensor is working properly.Thank you!
Resolved! Regarding the issue where the ULD API of vl53l1x fails to obtain the ranging result
I wrote the i2c communication code for the vl53l1x ULD API in vl53l1_platform.c and i2c32.c, and called the API in tof.c to initialize vl53l1. The VL53L1X_GetSensorId function can correctly read 0xEACC, but the VL53L1X_CheckForDataReady function alwa...
