I read HifiBerry's disclaimer about touch screens but I still can't figure out if the Waveshare 3.5 screen I just bought might work or not along with any of these two Hifiberry boards I already own, they just plug into the rpi GPIO, and I meant to plug it into the berry. Software might be HifiBerry OS, volumio, piCorePlayer, peppy. No problem there. I want to build a small audio player with a screen for fun.
This is what I got from the waveshare site (provided I actually get this board, still not arrived). Thanks to anyone who tried this!!
