Hi Carmine,
currently, I try to write an application, that is using spdif. I stick on using spdifrx with dma and I have no idea, why my application is not working (https://community.st.com/thread/37147-problems-with-spdif-rx-and-dma). I don’t know, if it is possible, but may you write a chapter you to analyse systematically problems like mines.
