vl53l8cx_def.h File

Rhagg28 · ‎2025-10-04

Hello,

I am having a hard time finding which software pack this file vl53l8cx_def.h is in?

I think once I get that I should be get the zones if Im understanding the error correctly. Please advise.

If it helps with the solution I am trying to use the P-NUCLEO-53L8A1 and VL53L8CHV0GC to generate 3D point clouds.

This is an interesting one...

Somehow you are trying to build without using some configuration or other and it's sending you the wrong direction.

If you want a point cloud, you don't need the VL53L8CH. It can do it, but you are wasting a lot of bandwidth sending Compressed Normalize Histogram (CNH) data around.

Take your setup and use the code for the VL53L8CX code - you already have it downloaded -STSW-IMG040.zip.

Just build that and you will get the distances for each zone. And from that you can build your point cloud.

And with a little luck, learning how that code works will show you where you went wrong building the VL53L8CH code. (Although I have to admit, I cannot understand where you went wrong. )

Hi Rhagg28,

Could you please let me know what software package you are not seeing vl53l8cx_def.h in? We took a look on our end and couldn't find it either. I need to ask internally about this file.

Hello John,

Thank you for your help and insight on these things. I am new to this and eager to learn.

Are there any youtube videos that you could recommend for beginners?

Best Regards,

Ryan
