idle: a 32kHz block-audio buffer will convert from 22kHz PCM, as 11 to 16 samples, w/ an 0.23% drop in playback speed. seems acceptable.
Integrating the DMAC with DRAM/CPU cache interfaces may still be significant work but it's one-time not per-peripheral.

ok, makes sense, may do this eventually. as-is, have both audio and display to deal with (display would need to send 16 scanlines per ISR).
Thanks. Twitter will use this to make your timeline better. UndoUndo
