Hello,I am using the VL53L8CX ToF sensor (I2C) and have encountered an issue. Currently, I’m not using a coverglass, and I have set the sensor to an 8x8 resolution with a frequency of 15 Hz.The problem is that when I run the sensor in an infinite lo...

I’ve been using the "vl53l8cx" sensor to measure distances through I2C, and I noticed that when I measure distances (between 10cm and 50cm), the values reported by the sensor are consistently half of the actual distance. For example, when the actual ...

Thanks! I am still troubleshooting.Voltage was one of the problems, and I have more question.I am using the Raspberry Pi 5 as the MCU, which has an internal 1.8k pull-up resistor. The VL53L8CX has a 2.2k pull-up, so I wonder if this could be too high...

Wires are alredy short enough.I2C connection has no problem.I think power is not the reason because we keep supplying power and my code (python) assigns 30% of CPU when running.What do you think about adding defensive code to reinitialize the driver ...

I guess 15hz was too fast to continuously getting data. So I set 10hz and it runs well. Which frequency do you recommend for long time measurment like a few hours.
