Dan Halbert bd6826496c Fix various RP2040 audio dma things: (see detailed commit message) ... 1. Check for correct error values from dma_claim_unused_channel. 2. Introduce a .stereo flag for simplicity. 3. Clarify PWM carrier frequency choice. 4. Start introducing quiescent audio value. Still need to ramp up/down. 5. Redo audio stop logic a bit. 6. Fix (unrelated) displayio dependency things. There is still an interference problem between other DMA users and audio. Still debugging this.		2021-07-08 08:14:49 -04:00
