If I point my VL53L5CX unit at the ceiling which I have measured to be 2.13m above my device, I get some readings that are status 5 of around 2100 mm and some readings that are status 255 of around 2100mm. Why is this the case? Because 2.1m is within...
first i test the code with the black board and I read data normally,I designed my round board by reverse engineering of the black board,I test my round board with the same code, but I got an error as shownin the attached picturesif any one can help p...
I'm doing tests on the VL53L3X evaluation board, and trying to reproduce the detection rate issues.In fact, it is hard to get the 50% and 94% valid outcomes out ofcertain large number of tests using the quoted reflection material, ambientlight condit...
Hello,Well i have read the documentation on the VL53L0X and it is a clear as MUD with respect to the usage of the function VL53L0X_PerformOffsetCalibration how to use it and why i should use it. I thought these devices where factory calibrated, but i...
I am using a VL53L1X with the VL53L1X_ULD library.I have one ToF sensor that I initialize at the default address 0x52 and reset to an address of 0x56. It works at that address (I am planning to add more sensors, but haven't hot there yet.)When I powe...
My use case would benefit from high speed but I'm having trouble getting it to run at 60Hz. I'm using the X-NUCLEO-53L5A1 on an NUCLEO-L476RG board with the XCUBE-TOF1 software. I'm using the SimpleRanging example program: XCUBE-TOF1\Projects\NUCLEO...
I used X-NUCLEO-53L5A1 + 2 VL53L5CX-SATEL, and the data read output speed has a delay in the code: HAL_Delay(POLLING PERIOD), POLLING PERIOD == 1s, and then I want to quickly, so I canceled HAL_Delay() (Picture1), But it took a long time to check (Pi...

Hi,I'm building a project that uses 20 VL53L1x sensors to detect any people or objects that go in the danger zone of a machine.The sensor will detect any objects or people below 2 meters distance. We set up the sensor 30cm above the ground.The measur...
Has ST done any research into the level of vibration these sensors can safely withstand? I'd like to use these on an application which experiences intermittently high vibration (up to 15m/s^2, mostly parallel to the sensor measurement direction). Acc...
