Hello,For a project I would like to use the VL53L4CD or VL53L4ED to measure distances in the range of ~1 cm to 80 cm. The expected ambient temperatures can vary (maximum between -10°C and +80°C, although the temperature will usually be in the range o...
Hi, Is it possible to get some sort of frame timestamp from the evaluation boards? Ideally, I would love to have start and end of exposure timestamps but any timestamp from the sensor would be great. I could timestamp when I receive the frame on my d...
The STSW-IMG009 VL53L1X ULD API (Ultra Lite Driver Application Programming Interface) has a bug in the function VL53L1X_SensorInit that blocks the code from being executed if status |= VL53L1X_CheckForDataReady(dev, &tmp); write 0 constantly in tmp...
Do the current VD56G3 drivers support the CM5 module? I have followed the installation guides several times (including building libcamera from the ST source files) and I can't get libcamera to stream the camera. Here is the error message:$ libcamera-...
Hi, I'm curious to see if it is possible to connect more than one STEVAL-EVK-U0I boards to a computer and read images of all of them? The SDK has an init function that allows you give a board id, but it is unclear what the board id means or if it wi...
Dear ST team,Hello, I am using the VL53L1CX with the 3.2.1 library and have noticed that when measuring the distance to an iPhone, the results are not very accurate and tend to jump between several different distances. Is this caused by the iPhone’s ...
Hi All,I'm developing a proximity switch using VL53L4CDMy unit works perfectly 99.9% of the time but I’m seeing occasional instances where the unit triggers very briefly even when there’s nothing in range. It may go an hour between such events, even ...
Hi,I'm working on a people counting system using the VL53L1X in multi-zone mode with a single sensor. It works well in general, but I'm seeing accuracy issues when people wear black or dark clothing—likely due to low reflectivity.I’d appreciate some ...
Hi all, I'm back with another question re: our 5-TOF setup (VL53L4CX x 5, all 'looking' out of the centre of a spherical sculpture, trying to detect and interpret people approaching and interacting with it).I posted earlier about trying to multiplex...
I'm trying to port the VL53L0X library for use with the RP Pico W for academic reasons, but I can't map the calls between the VL53L0X SDK and the RP Pico W SDK. For example, the function int32_t VL53L0X_read_multi(uint8_t address, uint8_t index, uint...
