I'm able to read/write registers and play the hello. My problem was, obviously now for me, my implementation of the SPI byte exchange.
Here is the MP3-Hello code for PIC24s, maybe of interest for someone who is experimenting too with PIC and VS1053. As far as I understood it should be able to play other Hello formats (endFillByte was implemented).
Important for PIC24s is to disable the SPI befor speed changes and reactivate it after change.
PS: my future step will be to implement my player as standalone under the VS1053.
