ebai101 Are there any resources available for modifying the Bela cape?
No, just the schematics, PCB and BOM (...) Oh, and our consultancy services, drop us a line at firstname.lastname@example.org if you are interested.
ebai101 However, I have tried in the past to compile a program without the cape on, and it seems that the software checks for the cape before going forward.
Without the cape on, the program fails to initialize the codec and therefore stops. There is no check for the SPI peripheral. As long as you use the same codec on the same pins, you should be fine.
