Resolved! VL53L5 + Nucleo-401RE: I2C communication buggy

Hi,I'm using CubeIDE 1.9.0 with X-Cube-TOF1 package 3.0 on a Nucleo-F401RE with VL53L5A1 expansion.I want to create the simple ranging example application with additional crosstalk calibration. I followed the steps from software package user manual U...

Resolved! Hi all! When is the new VD55H1 sensor going to be released? Any date set?

Resolved! VL53L1X: Will multiple sensors be able to work together?

We are trying to extend the FOV of this VL53L1X sensor, and our current idea is to use multiple that are overlapping. Will these sensors cause interference with each other when they are close together?

Resolved! Reduce noise when targeting reflective curved surface

Hi, We are trying to measure distance from our sensor through an IR Translucent plastic to a curved metal surface, using a VL53L1X. We are getting reasonable results by they are rather noisy (~10% deviation at times)What sort of changes should we be ...

Resolved! I am trying to make use of the VL53L0X API on stm32cubeide but I've encountered some issues coming from the file vl53l0x_i2c_win_serial_comms.c. Apparently INFINITE, WAIT_OBJECT_0 aren't declared and HANDLE is an unknown type name.

I thought HANDLE was part of the stm32 hal library so I tried including stm32h7xx_hal.h however it did not resolve the issue

Resolved! Calibration: Is it necessary if only the change in distance is the important value?

In our application, we don't necessarily need to know the true distance, we only need to know when it's in a certain range, and it doesn't matter if that range is represented as 30-40mm or 50-60mm, only that is consistent. Can we get away with not ne...

Resolved! What impact should sunlight have on the returned value?

From what I gather, sunlight causes the sensor to return a much larger value. Should this always be the case? Or is sunlight going to cause a variety of different values. I have mixed results in testing.

Resolved! VL53L5CX gasket requirements with cover window and large air gap

As exposed in the Application Note AN5231 of the VL53L1CX, a gasket may be required to limit the negative crosstalk effect if a cover window and a large air gap were both present. Is there any similar Application Note specific for the VL53L5CX model?...
