For a medical device that use NIR light we are using the VL53L4CX as range detector. We found that the TOF sensor light interfere with our NIR lighting system. In order to perform some simulations we would like to have some more details about the lig...
We found a problem with VL53L1CB, After VL53L1_GetMeasurementDataReady returns 0, VL53L1_GetMultiRangingData returns VL53L1_ERROR_ZONE_GPH_ID_CHECK_FAIL. What causes this problem?Thank anyone for a little help
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...
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...
