I'm trying to get back to learning FPGAs and how to program them. The issue I'm having is understanding were to find the information to interact with the FPGA side. I wanted to create a basic program where I have an AND or some other basic input/output created in the FPGA fabric and that would then be used by the MCU side. \
I've worked through this https://www.youtube.com/watch?v=Mb-cStd4Tqs video and can get it to run, but I can't figure out how the MCU interacts with the UART created in the FPGA fabric. Any help with this would be greatly appreciated.
