在同一条i2c总线轮询使用两个vl53l1x出现只有一个有反应的问题
这是我的代码，我之前以前改地址成功了的，这里就开始测量数据while (1) { // 获取当前时间作为起始时间 clock_gettime(CLOCK_MONOTONIC, &start_time); // 获取起始时间 for (i = 0; i < 2; i++) { // 轮询两个传感器 Timeout = 0; dataReady = 0; // 检查数据是否...

STM32 Smart Presence Detection VL53L8X
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...
Resolved! Vl53L5CX/L7CX - How to recover from from TIMEOUT_ERROR or CORRUPTED_FRAME
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...
Resolved! VL53L8CX SPI communication
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...
Resolved! VL53 as a reflectometer
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...

Resolved! P-NUCLEO-53L7A1 Expansion pack is not really compatible with gesture recognition demo
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...
Resolved! EMVA1288 Datasheets
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...
Resolved! VL53L7CX SDA stuck at zero
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?
Resolved! The interrupt of VL53L4CD cannot be used
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...
