VD6283 compute IR optical power
May I ask how to convert the IR channel ADC value of VD6283TX45 to IR optical power, only the RGB channel is converted to Lux in Driver, and there is no description about this IR optical power in Datasheet.

Resolved! How to achieve greater measurement precision close to Vl53L4CD?
Greetings!When I measure objects closer than 10 mm from the VL53L4CD, the result deviates significantly from what was expected, and the result also varies significantly depending on the texture and gloss of the object.Is it possible to configure the ...
TOF VL53L5CXV0DH/1 bad detections with status 255
I’m using a VL53L5CXV0DH/1 sensor in my current setup (see pictures). The goal is to detect a ball rolling between the sensor and the background. The red box is about 12cm apart.The settings is 4x4 for speed, i also noticed that 60 is not the highest...
VL53L8CX not accurate distance
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 ...
Proper VL53L1X calibration procedure
Hi ST,I wanted to validate/confirm our Calibration procedure. When we calibrate prior to calibration we set timing budget and intermeasurement to what they are normally when our code boots up. So, during calibration we do the same. Can someone pl...
release note for vl53l8cx_buffers.h
The "vl53l8cx_buffers.h" file bundled with X-CUBE-TOF1 seems to have been updated several times, but I would like to know what problems have been fixed in each version. Please let me know in which document the revision notes is listed.Thank you in ad...
Resolved! VL53L4CD: Measurement and Consumption Issues
We are having issues with the VL53L4CD Time of Flight Sensor.The sensor works properly after initialization, but after some measurements it starts having problems. It either stops ranging or returns a ranging result similar or equal to the previous o...
Distance Measurement Using VL53L4CD - Range Measurement Update Delay
Hello all,We are once again using one of the VL53 TOF sensors for a close-proximity ranging application. For this application we are using code from the VL53L4CD_ULD_Driver.After initialising the system using the VL53L4CD_SensorInit function, we are ...

VL53L8 api init function didin't work, needed additional delay
Hi, I'm hosting a VL53L8CX with a STM32F4, 48-pin instead of the 64-pin on your eval board. There's a 5" flex cable between processor and L8. The vl53l8cx_init() function was failing. Slowing the SPI baud didn't help. Increasing wait time on line 276...
