Has anybody worked on SPDIF in and out yet?

I’m about to start coding up with SPDIFRX on Seed pin 28 (libdaisy pin 21) and SPDIFTX using SAI4 on Seed pin 27 (libdaisy pin 20). Just checking if anybody has already got SPDIF working to save re-inventing the wheel ? Or let me know if you’ve been waiting for someone else to take the plunge :wink:
