This week, I got audio output to work. Now, we have an easy-to-use streaming interface and can focus on the rest of the WaveShaper core. While it was mostly just pruning small errors in the protocol, it was fairly time consuming.
I have moved onto serial communications, attempting to get a structure up before the interim demo such that we can stream live music to show off the WaveShaper’s unique sound.
Progress is going slightly slower than I like, it has again been a bit of a struggle with an unfamiliar tool to bridge the HPS ARM-core with the FPGA fabric using AXI. Seeing as the deadline approaches, I am looking into using the Avalon-MM interface instead.
I am aiming to have an end-to-end music playing device by Sunday evening by integrating the SystemVerilog which we have so far been simulating on actual hardware.
This week, I also spent some time on a MIDI parsing state machine which is as of now just on paper.
