Cant get VL6180V1 to return ACK on I2C
Hi,i am trying to get STM32F301K8 to communicate with VL6180V1 ToF sensor on my custom board., via I2C (at 20kHz) I had problem getting the API to work so i tried low level I2C access by just sending 0x01 with basic HAL_I2C_Master_Transmit. I noticed...
VL53L0X crosstalk calibration
Hello. I'm using a VL53L0X sensor with cover glass from www.gilisymo.com, so I need to do crosstalk calibration to get an accurate measurement. The problem is that the correction is too big. The process is as follows: 1) SPAD calibration (ok)2) Ref c...
Resolved! We have a cover window that is a few cms away from the sensor.
NCao Writes:"We have a cover window that is a few cms away from the sensor. What kind of calibration would make the sensor ignore it?"
Resolved! VL53L1X address changing
Hello,We ordered some VL53L1X and put them on our PCB. We ran into a problem at the moment of changing the address: we can give these sensors only two address options 0x52 (default) and 0x53 so that they work correctly, but at other addresses the sen...
VL53L1X offset when detaching cover glass
We are using the VL53L1X with the ULD API in our products. During the production process, we perform the offset calibration process as described in UM2510. Our cover glass (Luxycryl red 1600) is actually separated with a light blocker to prevent cros...
Resolved! VL53L1x on breadboard
Hello community,I am trying to implement a simple people counter using a VL53L1X-SATEL on a breadboard with esp32. My problem is that I am confused about the wiring. I've read the data brief but as I am not an expert in electronics I cannot figure it...
Resolved! VL53L0X result deteriorate by 1mm with filter glass (recommended by ST)
We are using Vl53L0x for distance measurement up to 20 cm. While testing with filter glass (recommended by ST) we observed result deteriorate by 1mm for few measurement areas against results without filter glass. Now I will work cross talk calibratio...
Resolved! recommended Protection Ratings & Cover glass dimension, types for VL53L1X: ToF sensor
I wanted to use this sensors for person detection in Washroom pipe & urinal applications. I have tried different models of housings for sensor. But so many times, the taps are automatically turned on without any persons. So can anyone suggest me reco...
Resolved! VL53L1X operation sequence
VL53L1X has VCSELs and 16x16 SPADsWhat I am curious about is the order of operation when reading 16x*16 SPADs one by one.1. VCSEL on2. Read SPAD[0,0] value3. VSCEL off4. VSCEL on5. Read SPAD[1,0]6. VSCEL offwhether or not1. VSCEL on2. Read SPAD[0,0]3...
