Scott Shawcroft 360475e266 Implement audiobusio and enhance PIO for it ... This adds I2SOut and PDMIn support via PIO. StateMachines can now: * read and read while writing * transfer in 1, 2 or 4 byte increments * init pins based on expected defaults automatically * be stopped and restarted * rxfifo can be cleared and rxstalls detected (good for tracking when the reading code isn't keeping up) Fixes #4162		2021-02-23 15:50:00 -08:00
