Hi everyone,I’m having issues with the VL53L7CHV0GC ToF sensor drivers on Linux. The kernel module loads fine, but I can’t read any data using the userspace part. When I try to use the driver completely in userspace mode, it reports that it can’t fin...
Hi follow can make offset calibration？Place the object 14cm away .Must be in a dark environment? follow can make Crosstalk calibration? Place the object 60cm away. my coverglass like follow,The measured distance seems very short. How can...
Hi, we would like to use the VL53L7CH on Linux 6.12.Standard kernel interfaces are required:IIO/hwmon subsystems and regmap — no proprietary ioctl/miscdevice interface.Is an IIO-based driver for the VL53L7CH already provided or planned for upstream/...
Hello ST： VL6180X has been discontinued, but our older equipment still uses it. We hope to obtain the IEC 60825-1 CB test certificate to prove its Class 1 rating. However, this certificate is not available on ST's official website, whereas it i...
Dear altruist, I need urgent help. Can I apply hardware-based external triggering in the VL53L8CX sensor by STM32 Nucleo F401RE? Will the sensor work for external triggering? Thank you
Has anyone seen documentation or done optical power measurements for VL53L4CD? I’m trying to find the radiant energy or optical power output of this low power time-of-flight device. (I only succeed to find a graph showing the relative emitted power i...
Hi, We have incorporated a vl53l4cd into our product. We wish to measure 0 to 100mm with a resolution of 1mm, and an update rate of at most 1 second.We have set the vl53l4cd 19mm back from front measurement face (so we need to actually measure 19 to ...
Hi, vl53l0x in continue mode ,how to read data_status and in time mode how to set time and read data and data_status? thanks
Hi， the rear background exceeds 2 meters, and there are no obstacles in front of the sensor. The measurement data is unstable, and the reading sometimes reaches 0 and sometimes reaches 115.
STMicroelectronics support,I am testing a VL6180X laser sensor device for use in autonomous robotics.I currently get good distance measurements using an Arduino sketch but can't use that platform in my final product.Instead I'm using a pic18f46k22 mi...
