Hello, I have a FUNDAMENTAL question: TOF VL53 series sensors report a depth map. Is the depth the "Euclidean distance from the origin (0, 0, 0) to the point (X,Y,Z)" ? or is the orthogonal distance from the camera chip plane to the measured point a...
Hi I am using ST VD56G3 camera to capture .raw image from NXP IMX8m embedded board. I was able to capture the raw file using the following command. gst-launch-1.0 -e v4l2src device=/dev/video2 ! "video/x-raw, format=NV12, width=1120, height=1360, fr...
Good morning. I am trying to evaluate a P-NUCLEO-53L8A1 evaluation kit. I downloaded the software example from your website and unzipped it. I then attached the eval board to a USB port on my laptop (running Win 11). It enumerates as a STLink VCP. ...
I am attempting to write the platform code for the ULD to work with Zephyr. WrByte, RdByte, and RdMulti are running correctly, but the WrMulti function is throwing two types of errors:<err> i2c_nrfx_twim: Error on I2C line occurred for message 0<err>...
Hi all, I am new to STM32 programming. I have been able to write a driver for an ultrasonic distance sensor, flash the board, and measure distance, in Rust. Now, I am trying to get a STM32F401RE to talk to a X-NUCLEO-53L7A1 ToF sensor, connected via ...
Hello, I have started working with the VL53L5CX ToF sensor, for 3d scanning. I have successfully interfaced the sensor with MCU and am able to read the data from it. I have read the datasheet and um2884 user manual as well which explains the differen...
Hello,I'm currently working with the VL53L5CX sensor and I came across the following definition in the header files of the API provided by ST : #define VL53L5CX_STATUS_CRC_CSUM_FAILED ((uint8_t) 3U)However, this constant doesn’t seem to be used anywh...
Hi,is there a way to distinguish both mentioned sensors other than by complex optical measurements (they have different FOVs)? We have built devices with both types of sensors and our firmware calculates x/y/z coordinates from the reported distances ...
Hi All,I see two order codes for the VL53L5CX: VL53L5CXV0GC/1 (with liner) VL53L5CXV9GC/1 (without liner) The datasheet says the liner must be removed before mounting the cover glass, but it’s not clear when the liner version is required.Could any...
Hi,We are trying to mount the VL537CX ToF(Pololu) sensor on roof of a car and map a certain area of the cabin. The sensor is pointed downwards.But we are observing the a pattern flashing (appearing for a single frame of ToF data) at an interval varyi...
