Hi I am developing a commercial footfall counter based on the VL53L7CX and ESP32.
The API is (Version : VL53L7CX_1.2.10)
I have produced a mockup using the VL53L7CX breakout board.
IOVCC is 3.3 volts
I am using the on board regulator for AVDD powered from 5 volts.
I2C is 1 MHz.
I am using the 4 x 4 resolution.
I am only using the Results.distance_mm the rest of the Structure and I2C communication is disabled in the platform.h
I have developed a PC app to capture the ranges and visualize the range data.
With the sensor facing a blank wall 3000 mm away I am getting a mixture of ranges in the 16 zones with almost 2000mm difference on adjacent zones.
I have also found some zones just do not update their range unless you wave your hand in front of the sensor. This is not a data issue I am receiving the data it just does not change.
The worse problem I have is the range on some zones is intermittently fluctuating by more than 400mm between samples.
I have tried VL53L7CX_RANGING_MODE_AUTONOMOUS and VL53L7CX_RANGING_MODE_CONTINUOUS.
I have tried ranging frequency from 2 to 60 Hz (Along with Integration time 2ms to 1000ms)
I have tried setting the sharpener percentage 0 to 99
I have tried the xtalk calibration.
I have tuned out all the lights in the room is is no ambient light.
I can not continue with this sensor unless I can make the ranges consistent what else can I try?
Thank you.
