Hi， 1》In the dark，Place the white target 140mm from the sensor call function Status = VL53L0X_perform_offset_calibration(&vl53l0x_dev,0x8c0000,&pOffsetMicroMeter); 2》In indoor environments ，Place the black target 600mm from ...
Hello, I have a VL53 sensor that's outputing distance data but the distance measurements I'm getting are getting "stratified" into about 3 different distances seemingly randomly. I'm using the ULD driver on a custom PCBA with a TM4C1239 microcontroll...
Hi,I am using the STEVAL-EVK-U0I kit with the VD55G0 sensor and the provided Python SDK. Firstly, I wanted to say I really love the capabilities of this sensor and it looks extremely useful for my work. My goal is to capture high frame rates (200-500...
Hello, I try to get data from a X-NUCLEO-53L8-A1 board connected to a Nucleo board and visualize it in my computer. If I use the VL53L8CX Gui and connect my COM port and click on the start button, it is working well. However, I would like to get dat...
Hello, I have multiple VL53L0X sensors that I am communicating with over an STM32 board. Two of the sensors started throwing errors (only reading 8191), and so I moved them to an Arduino for the flexibility of using the downloadable API. They worked ...
I have performed crosstalk calibration of VL53L7CX ToF sensor using a 0.2 mm thick polycarbonate cover glass. I had used a sheet of white paper (assuming 80% reflections) placed at 600m as reference surface & 4 samples were used for calibration. ...
Hello,We have lately been seeing in some cases that one or two pixels seem to be stuck at distance_mm==0. Sometimes the pixel goes back to returning normal values after some time or after a power cycle, but sometimes it seems to report a zero value c...
ULPM for the MIPI CSI interface of VD55G1 is not clearly described.Errata (es0643) section "QVGA at 480 fps" say that we should put MIPI in ULPM. Why does this affect timing?WRITE_REG8 STREAM_STATICS_OIF_ULPM 'h01 # MIPI in ULPMIs this a MIPI setting...
Hello community, I am working with the VL53L0X Time-of-Flight distance sensor and the official ST API driver (VL53L0X API package).My hardware platform is: STM32H747I-DISCO board (CM7 core) I2C3 used to interface the VL53L0X FreeRTOS running on CM...
Hi,I was wondering if it's planned for the current STEVAL-EVK-U0I board to work with the 5 Mp VD5943 and VD1943 Image Sensors when they're launched in spring 2026 or if a new USB interface board is planned for evaluation of VD5943 and VD1943?The page...
