Pre-calibration ToF-Sensor VL6180X
Hi, I would like to know how the pre calibration of the VL6180 sensor works in detail and how it's affects the measurement. Can someone help me?

Ranging results values for VL53L4CD
Hi,I am getting started with VL53L4CD so as to improve our system under ambient daylight conditions, which is performing poorly due to current sensor VL6180x under such condditions.My application is:Waking up device when target detected closer than 1...
Changing the cross-talk calibration distances for the VL6180X
Hello!So in the project I am working on, we are using ToF sensors (with a cover glass) to accurately measure the distance of a white object within the ranges of 30-70mm. We would like to create a calibration fixture that also falls within these dista...
Resolved! Trying to interface Vl53L1X with a TI controller. What does the response 0xA5 from the sensor mean?
I am trying to interface the VL53L1x sensor with a TI controller. I have checked the I2C read and write operations on the board, and they are working properly. The data sent and received over I2C are correct. However, when I try to read Model_ID 0x01...
VL53L1X People Counting range status
Dear,What are the best practices for the people counting algorithm regarding range status? I often get status 2, so I lowered the signal threshold to 400. This reduced it, but did not solve it completely. What status codes should I allow, and which o...
What sensor or combination of sensors would provide the best accuracy in a range of 1mm - 1100mm?
I have read the data sheets for the VL53L0X, VL53L4CD and VL53L1CX ToF senors. I am unsure which one would be the most accurate as the datasheets present the accuracy data at different conditions.Ideally the sensor would be accurate over 1mm - 1100mm...
Resolved! VL53L1X problem with write value to register
Hello, I solve a problem with writing the value to the register of sensor VL53L1X. It is the main purpose, why the sensor doesn´t read distance because the init state is invalid. For example, I tried to write the value 0x2 to the register 0x30 on the...
Resolved! Finding the VL53L1X XTALK calibration distance
I am trying to perform the XTALK calibration for my system that includes a coverglass on top of the sensor. I am not exactly sure what the point of calibration should be. I've read in the forum: "When doing crosstalk calibration you need to find a ta...
Timing budget not kept in VL53L1X
I am trying to get consecutive measurements from the VL53L1X sensor but the timing budget is only kept on the first measurement with the below codeVL53L1X_BootState(dev, &sensorState); VL53L1X_SensorInit(dev); VL53L1X_SetDistanceMode(dev, 2); VL53L1X...
