Hello,I'm in doing a project to measure the distance of my car from the wall. I'm in the software development phase using an ESP32 and a VL53L4CX to measure the distance.I'm using ESPHome to develop the entire thing and due to the reason there is no ...
I read that we can not set spad array size on VL53L4CX chip. What is the purpose of function VL53L4CX_SetUserROI, found in VL53L4CX driver? I tried setting two zones or two user rois but detection doesn’t change.Damjan
We are trying to use a VL53L7CX sensor for a people counting application, but some zones won't change fast enough after a person passes through the detection field, even after a long time like 2-3 seconds. I tried resetting the sensor after each rang...
Hi,I am having an issue with the VL53L1CB TOF sensor where I cannot communicate with the sensor via I2C. I have everything configured correctly as far as I can tell but the API is returning status error -13. I am testing with a L476 nucleo and the SA...
Hi, Is there any documentation for recommended cover glass designs for the Time of flight sensor VL53L7 (materials, thicknesses, sizing)? Or any other documentation about housing this sensor? Thanks!
VD56G3 programmers guide? Is this availible?Also the hardware interface description documentation?Also, is there a dev kit availible for this?Thanks in Advance! We need a hardware interface doc and programmers guide. Alos a pointer to where we can ge...
VD56G3 template driver would be useful but also a spec for the registersets, som programming information, etc.Id like to evaluate thius device for future use using a driver that I cna run from various linux environments.Is ther a doc for programming?...
I try to use VL53L5CX ToF sensor with ST driver library in original version. Host MCU is ESP32 dev kit.During initialization procedure sensor returns error at step:status |= _vl53l5cx_poll_for_answer(p_dev, 4, 0, VL53L5CX_UI_CMD_STATUS, 0xff, 2);Befo...
I have attached a couple of histograms from same object and from different distances. Distances are embedded in filename visible in image (top bar). Problem is peak position doesn’t change. I understand depth data is spread across three bins only. Bu...
I use a glass for our VL53L1X sensor. But we found there is a crosstalk problem and have to use crosstalk compensation. We use VL53L1X ULD for our device. There are three functions about crosstalk.int8_t VL53L1X_CalibrateXtalk(uint16_t dev, uint16_t...
