I'll think about sharing the code. Large code parts - while working - did not pass my quality bar, since I did not have enough time to clean and refactor while learning. But maybe that's fine. Hmm.

Oh I think it's more than fine :)

Your goal wasn't to write a C++ or Python app it's was to create almost everything from first principles. I also don't think anyone would doubt your abilities after reading this post. You could link to the article in the repo. I think it's speaks for itself. My first thought when I read the article was "Wow, this is great." I've read it twice now. Thank you for sharing.

Here's the repo: https://github.com/fnoeding/fpga-experiments

I'll update the post with it too.
