Jeff Epler	68ac14b309	StateMachine: Add in_available property ... I named the property `in_available` because it is similar to pyserial. However, it indicates the number of words in the fifo, not the number of bytes.	2021-03-04 11:14:09 -06:00

Jonny Bergdahl	f7eac46c78	Update StateMachine.c ... Changed woring to use max instead	2021-02-27 00:07:30 +01:00
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

Scott Shawcroft	733094aead	Add initial RP2040 support ... The RP2040 is new microcontroller from Raspberry Pi that features two Cortex M0s and eight PIO state machines that are good for crunching lots of data. It has 264k RAM and a built in UF2 bootloader too. Datasheet: https://pico.raspberrypi.org/files/rp2040_datasheet.pdf	2021-01-20 19:16:56 -08:00
