HiI am using Vl53L1X to measure dark surface upto 1000 cm far.. I am using a split cover glass(specifications attached). The benefits of using the split cover is that it prevents crosstalk. But even after attaching the cover, the distance measured by...
I am currently trying to control a VL53L8CX sensor via SPI communication from the microcontroller mounted on a Crazyflie drone.However, inside vl53l8cx_check_data_ready(), the values in temp_buffer became as follows. Indices [0] to [2] look correct,...
HiI have been messing around with VL53L4CD for the last few months, and I recently realized that my readings differ significantly, depending on the target color/texture.Here is my setup: The sensor is set on its side, and directly in front of it, at ...
Title: VL53L8CX pulls SCK line low on ESP32 – PCB or power-up issue?Hello everyone,I’m currently developing a prototype using a VL53L8CX sensor together with an ESP32 controller. On our PCB, the sensor seems to permanently pull the SCK line low. Thi...
I've interfaced the VL53L4CD with ESP32-S3, but I'm unable to get accurate ranging values below 70mm.I'm using the ESP32-S3 with Arduino IDE.How can I resolve this issue ?#include <Wire.h> #include "vl53l4cd_class.h" #define SDA_PIN 8 #define SCL_PI...
Hello, I have a question about the temperature calibration for the VL53L0X Time-of-Flight sensor.The UM2039 manual states the following:> [Temperature calibration] has only to be done before offset and cross-talk calibrations, after Reference SPADs ...
Hi, Was wondering if there is any info on when the VL53L9CX is expected to be released? Regards
This is a continuation from this post, where I erroneously marked the post as solved: https://community.st.com/t5/imaging-sensors/vl53l7cx-distance-data-stratification/td-p/866073Unfortunately I'm still experiencing the issue where range data continu...
HeyI've got great success with the VL53L4CX at sorter ranges, but at longer ranges i seem to get two objects. One closeby between 10 and 30mm away, and one at the distance that it should be.I've done calibration and i cant' get this to go away. I'm a...
Dear all,I'm trying to get a VD55G0 sensor (promodule connected via P-board) working on a Raspberry Pi 5. I followed the Linux Start Guide for the driver. The only difference with respect to the guide were the name of the device tree file (guide says...
