8065ab73a4 WM8904: Add reset logic to put the part back in its initial state after playing each WAV file. Base samles per second on frame length, not bits-per-sample. Use a different frame length for 8-bit and 16-bit data 2014-08-04 19:26:43 -06:00

dc8b040573 WM8904: Correct calculation of bitrate (I am not sure why this is correct). LR clock divisor is now a constant 32-bits per frame. Conditioned out interrupt logic; it is not being used. Also added some FLL lock interrupt/poll logic (which was subsequently disabled). 2014-08-04 15:08:20 -06:00

3b8c4a399d Framework for a WM8904 audio driver. The initial driver check-in is simply Ken Pettit's VS1053 driver forced to compile with only WM8904 definitions 2014-07-18 15:35:12 -06:00
