Hello! New here
For fun I would quite like to see what I can do with audio on the ICE40 (B2 B2X) because of the limited pins I am trying to do it with I2S. I have never done any proper FPGA work, know if there are enough LUT’s to do anything useful or written an I2S interface but hey! I thought jumping in the deep end may be interesting!
I forked the B2 computer project board and picked a PCM1803 ADC and PCM1754 ADC as they were on the simpler side of the converters I could find on TI’s website. It might be a bit noisy but this is where I am so far.! I know perhaps I need to fit in some kind of RAM e.g if I want to do a delay as the internal ram a bit too small for say 1 second of delay @ 96kbps. Also the inputs and outputs have quite crude passive filters, may need something active.
