Greetings.If I point the sensor at a wall and then slowly move my hand into the sensor's viewing area, the sensor gradually changes its reported range from the distance to the wall to the distance to my hand as shown in this graph.Is it possible to s...
I checked the Application note "AN5561", VL53L3CX maximum ranging performance improvements. I had a question about "1.3 Maximum ranging distance".The performance of Medium distance mode seems to be better than the one of Long distance mode. I though...
Hello, I am trying to set up a custom PCB with multiple sensors, including the VL53L3CX. As MCU, we are using the STM32G441KBU6, which seems to be too small for the bare driver API, and we did not find any acceptable alternative to the MCU. Is it pos...
If I want to take multiple readings on a VL53L1X at different ROI's, I need to set the optical centers for each ROI sequentially, one for each measurement.But when exactly do I do that, and what are the pitfalls?e.g. I have a timing budget of 20ms, a...
I have a sensor part no VL53L1CBV0FY/1 I use driver version 6.6.1.GetDeviceInfo reports:Name: VL53L1 cut1.0Type: VL53L1Product type: 0Version major: 1Version minor: 0My initialization sequence is like this: status += VL53L1_WaitDeviceBooted(Dev); st...
I have 6 VL53L3CX sensors connected via the same I²C bus. For this reason, the I²C address of each sensor must be changed as described in the UM2778 User's Guide.Does this procedure have to be carried out each time the device is restarted or disconne...
That's not meant as a question, more as an input/feed-back for ST developers or users of the VL53L0X device.I have a custom PCB with STM32F091 and two VL53L0XSymptom:If I initialize one only of the sensors, that sensor works great and gives good res...
I am using VL53L1X for indoor presence detection, mounted on the ceiling and looking at the floor, and it is doing great. However recently I tried it in a new location, and I have nothing but errors. I have several sensors there, and all of them are ...
