uelen	f840d27b8e	Demo commit ... The audio output is still messed up, but this commit gets everything as ready as it can get. Fixed up all the testbenches and added state machines for everything	2025-06-10 13:26:35 -07:00
uelen	fe227d1b61	Broken SD card ... How tf did it break bro	2025-06-09 15:41:13 -07:00
uelen	71eecd18e8	Added modules to read sdcard data and cmd response ... These were realy headaches but the testbenches are passing. We need to take a look at the audio_buffer testbench for sure, it is way wrong and needs reworked to use the interface. Should do a pass through every module probably.	2025-06-07 21:57:17 -07:00

uelen	dff929de84	Initial work on rom_sd ... This module needs way reworked to just be a state machine. I was trying to get way too tricky with it so I went back to the drawing board and made a state machine diagram for it. The diagram is included with this commit. I also moved the current collection of documentation to a doc/ folder, and added a second-long audio rom to test everything out once the rom_sd is working.	2025-06-02 14:02:50 -07:00
