Development Version with AprilTag 3 on N6 an F7 Board

The new Development Version with the AprilTag 3 Library perform on the N6 Board really fast (about 17 fps at QVGA compared to 2 fps).

On the F7 Board I get always an Memory Error on QQVGA and on QQQVGA.

We’ll fix it soon. Note I have two more optimizations in the works. If you can build the firmware and would like to test something see:

It should speed up AprilTag even more!

Thank’s for your work on optimization.

But also in the newest Development Release (1ecc19a) I get the same error message:

“MemoryError: Out of fast frame buffer stack memory” on the OpenMV-F7 with QQVGA and QQQVGA.

On the OpenMV-N6 the framerate increased to 25 fps at QVGA.

Hi, I am home traveling from a sales trip tommorrow. I will send a patch to fix this then. I have M7s at home I can test with.

I see on github that you already fixed this issue.

How can I test this on my OpenMV F7 ?

If I download the newest Development Version the fix is not included ?!

It hasn’t been merged yet, it will be soon. We’re also working on multiple other fixes.
