Hi,Im currently testing the Smart Presence Detection Firmware for the VL53L8X and have some questions:- When I start the ranging, the firmware triggers false positives (detecting someone when there isn't anyone) and after some seconds it stabilizes t...
Hi All,we are currently working with both the VL53L5CX and L7CX ToF-Sensors.In EMC testing, there are sometimes occurences of the statuses TIMEOUT_ERROR and CORRUPTED_FRAME during the acquisitons (via the Vl53lxcx_get_ranging_data uld function).If th...
Hi all,I'm trying to setup the SPI communication with a VL53L8CX which is connected to a STM32F401RE-Nucleo. I took some code snippets from the STSW-IMG040 package and I wonder why the bytes to be send in VL53L8CX_WrMulti and VL53L8CX_RdMulti are tre...
Hi,I want to create a reflectometer to measure samples targets reflectivity in %. The samples are 10x15cm and the distance will be fixed: samples can be between 15cm to 1m. The measurement will happen in the dark in a controlled environment.I found t...

Hello, I have two expansion boards: X-NUCLEO-53L8A1 with VL53L8 and X-NUCLEO-53L7A1 with VL53L7CX. I used a gesture recognition example project for NUCLEO-F401RE board I found on this page: https://www.st.com/en/embedded-software/stsw-img035.html?icm...
I am exploring STM image sensors for a new project and am evaluating different options. To make an informed decision, I would like to refer to EMVA1288 datasheets, especially for details on read noise and dark current performance. Could you please le...
Hi, I am testing the SATEL VL53L7CX board, but the SDA on this board is stuck at zero. I have checked that there are no short cuts and that the pull up is there. Any ideas how to solve this?
I found a problem while using the VL53L4CD. My usual practice is to initialize the VL53L4CD after the terminal is turned on. During subsequent use, I only use Start and Stop to control whether to start ranging.Now it is found that when I stop, the te...
Hello Everyone ! I would like to know if it is possible to measure ambient light levels either directly or indirectly , using the VL53L8CX sensor. Thank you in advance
