Hi everyone,I'm thoroughly flummoxed and in need of guidance. I have a VL53L4CD rangefinder on the SparkFun breakout board that will not play nice with my Raspberry Pi. Long story short, the rangefinder seems to be ACKing prematurely under certain ...
Hi,I noticed that the number of spad used reduces as an object gets closer to VL53L4CD. I was thinking about using this to make my distance measurement better. It also helps me to detect if the object is moving much in the field of view as i noticed,...
Hello, I've previously posted asking about gesture and hand posture output and I've finally got an output from both of the model. The problem is the method of getting an output for gesture and hand posture is different. For gesture, I'm able to use G...
I'm evaluating the VD55G0 sensor - using the cam-55g0 camera module and the STEVAL-EVK-U0I evalkit. Looking at the datasheet and other documentation (VD55G0 - Compact and high-sensitivity 0.38 megapixel monochrome global shutter image sensor - STMicr...
Hello !If you don't mind, could you tell me about how to calculate human position (x,y,z) in STSW-IMG048?In 8x8 mode, I can get 64 values. I'm wondering about how to calculate the position from the values.Any form of help is appreciated. Thank you!
In vl53lx_platform.c functions VL53LX_WriteMulti() and VL53LX_ReadMulti() are taking care of the VL53LX_COMMS_CHUNK_SIZE which was set to 56.So, data is send in telegram chunks if length exceeds this definition.I'm wondering if this is due to VL53L...
Hi, I am using a VD55G1 sensor with P-board to interface with Rpi 5. I am using Camera port #0 of Rpi. I downloaded the STSW-IMG506_V4L2, STSW-IMG506_LIPA and STSW-IMG506_LCAM. I followed the steps to install V4L2 driver from the "Linux Start Guide f...
When i measure my distance in 4x4 i don't have any issues at all. But I need to change it to 8x8 for my project.To my knowledge you only need to change the resolution with vl53l5cx_set_resolution() to 8x8 and adjust the frequency accordingly. I have ...
I am using the STSW-IMG501 software with the STEVAL-EVK-U0I1 evaluation kit and the STEVAL-56G3MAI1 evaluation board for the VD56G3 image sensor. I am trying to capture videos of my target application at high frame rates to assess the sensor propert...
Hey, I am a beginner in all of this and have been trying to change certain parameters for my VL53L8CX sensor such as sharpening percentage, or converting its standard mm data unit to feet or inches, and I really can not figure it out. I am guessing i...
