I am using a pcb4188_vd66g1 camera module with a Raspberry Pi 5.The system has been freshly set up with Raspberry Pi OS 64-bit, and I followed the official setup guide step by step.After completing the setup:The camera is detected correctly when runn...
Voltage drop when measuring with VL53L0X
Hi everyone,I’m working with the VL53L0X sensor and I noticed that when it starts ranging, the supply voltage (of my board with the VL53L0X, the Vcc pin) drops from 3.389 V down to 2.544 V.In this setup, the VL53L0X is powered from the 3.3 V pin of a...
Self test for vl53l8cxv0gc/1
Hi,Currently, we are testing vl53l8cxv0gc/1 by placing an object in front and moving it and reading the values. Is there a way to test the functionality of vl53l8cxv0gc/1 in a production environment? Is there a self test mechanism for this sensor?Tha...

Is it necessary to perform offset calibration when measuring liquid levels with the VL53L0X?
Hi everyone,I’m currently using the VL53L0X sensor to measure the liquid level inside a container, and I have a question regarding the offset calibration procedure described in the documentation.Is it really necessary to perform the offset calibratio...
Resolved! VL53L8CX - Unable to use detection thresholds while in Autonomous mode.
Hello,I have been using the this ToF sensor along an ESP32-WROOM MCU for a while without major issues. My impementation of the i2c interface seems to be working well since in most simple ranging cases everything works well.However, recently, i have b...
Error in VL53L1X datasheet
On page 9 of https://www.st.com/resource/en/datasheet/vl53l1x.pdf, it is written:"Ranging is continuous, with a programmable delay between two ranging operations (called anintermeasurement period)"This is wrong. It should be:"Ranging is continuous, w...
