Currently, I'm working on a project to detect human height, but the measured height appears shorter under strong ambient light. I would like to know if the ambient light affects the distance measurements
We placed two VL53L1X sensors at 18.6" in our temperature chamber. Over a 50C swing we saw up to 1.15" of variability. In the images bellow the chamber temperature stabilized around 30 minutes. The target was a large 24x24 sheet of white nylon 0.5" t...
Hi, I am trying to integrate the VL53L8CX ULD driver with a project that utilizes chibios on an F4 based board.The TOF sensor firmware seems to be about 86KB. For a transfer of this size, the device fails to setup and use DMA-safe bouncebuffers. I ca...
#define RANGE_ERROR_DISTANCE_BELOW_DETECTION_THRESHOLD 0x03#define RANGE_ERROR_OTHER 0xFFHi ST,Some of our production devices are receiving the above errors. Can someone help me with understanding what might cause these errors?Thanks,Will
hi i want to confirm can i use single vl53l3cx for depth mapping, i know that i should use l5,l7 or l8 but these not available in my country? and also since vl53l0cx the cheapest can i multiple of those too for the same?
There are three modes: LONG, MEDIUM, and SHORT. The names suggest that LONG allows measuring the greatest distances. In document UM2923 (section 5.2), there is information that the maximum distance can be achieved with the MEDIUM setting. What settin...
Hi everyone, I have STM Nucleo-F401RE and X-Nucleo-53L7A1. I downloaded the SDK en.X-TOF1. When I check the pin configuration, I saw that X-Nucleo-53L7A1 I2C_RST (PB3) pin is SWO pin on F401RE board at the same time. I needed to delete PB3 pin config...
I have an STM32 Nucleo F401RE plus X-Nucleo-53L3A2 board.IDE and the rest of the toolchain installed, including the STSW-IMG016 P-NUCLEO-53L3A2 pack graphical user interface.The data brief of the GUI states "I2C transaction recording" which is of my ...
I'm using the VL53L1X ULD API to drive 4 sensors and, sometimes, the function VL53L1X_SensorInit returns error VL53L1_ERROR_CONTROL_INTERFACE while initializing the third or four sensor (the first two are always initialized correctly).The sensor boot...
We currently use the VL53L1x and have struggled with precise measurements to close objects. Our application needs precise measurements between 1mm and 400mm. Reviewing the available sensors ST has it appears to us that the VL53L4CD is the best possi...
