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...

VL53L1_ERROR_ZONE_GPH_ID_CHECK_FAIL
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
Resolved! VL53L4CD (ULD) not ranging?
We are moving to VL53L4CD.Have it all coded but having a strange experience. Simplistically we use the sensor continuously and only use GetResult to retrieve the sensor readings (e.g. not CheckforDataReady).So, simplistically looks sorta like this ...
VL53L8CX at 60 Hz
I am trying to run a VL53L8CX sensor at the maximum advertized speed. Originally, following the marketing for this chip, I had thought that this was possible at the full 8x8 sensor resolution, but later learned that that has a maximum speed of 15 Hz ...

Compare VL53L1CX and VL53L4CD, it seems VL53L4CD consume much more power
Hi All,we tried to migrate from VL53L1CX to VL53L4CD for better precision in short range.both use ULD driver, we expect they work in similar way however it seems not.we set both to TB20 and compare power consumption in single shot case. It seems VL53...
Resolved! Integrating TOF and SPD with VL53L8CX - second try
(I deleted the content by accident) I'm working on a project that uses Smart Presence Detection to control a LED strip using the X-NUCLEO-53L8A1 board. I started a blank project in STM32CubeIDE and included the X-CUBE-TOF1 bundle. I have added severa...
VL53L1X Calibration reboot
Hi, We use the calibration ST APIs. The procedure we follow is run calibration and then reboot with the new offset. However, is there anyway to avoid having to reboot? We would like to auto calibrate in real time without a reboot if this is at all ...
VL53L8CX will not initialize correctly on big-endian machine
If your VL53L8CX gets past the 'is_alive' function but you cannot get it to run, it might be because you are running on a big-endian machine, and the ST code you downloaded assumes a little-endian machine. Try swapping your vl53l8cx_is_alive function...
VL53L4CX Interface with STM32F030 DEMO Board
Hi team,I am new to the STM32 Cube IDE environment and would like to interface and control the VL53L4CX Time-of-Flight sensor using an STM32F030 DEMO Board. I kindly seek your guidance and support in achieving this.Here are the details of the hardwar...
