Ben Kurtz	0e187cb34c	Implement Teensy-LC DAC audio playback - switch to single-DMA architecture (was having to manually reset address/byte counter each time anyway, so no real benefit of using two) - add 2-block output pipeline (mirroring Teensy 3.x) - (sneak in timer frequency increase - may want to revert this) - actiate DMA on timer expiration (required to use DMA from timer) - have to manually enable DMA after setup and after each call to isr - implement isr - check if dma is done (not sure this is required, but thought I saw it call once when it wasn't, and in theory you get called on errors too) - reset source buffer to point to other staging memory - re-enable dma at completion - otherwise similar to teensy3.x version	vor 4 Jahren
