Performed filesystem operations at the same time to stress test it. The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on. 2021-03-04T17:26:33+00:00 Jeff Epler jepler@unpythonic.net 2021-03-04T17:13:55+00:00 urn:sha1:bd01d31542f1d83797ecb2ac4a4a16ba0235a988 This can be used where the standard API calls for a list of pins, to check that they satisfy the requirements of the rp2pio state machine, e.g., ```python def __init__(self, pin_a, pin_b): if not rp2pio.pins_are_sequential([pin_a, pin_b]): raise ValueError("Pins must be sequential") ``` 2021-03-04T17:26:29+00:00 Jeff Epler jepler@unpythonic.net 2021-03-04T16:03:31+00:00 urn:sha1:ff62b0d2c020cffb910ad15e81897b41e92380fa 2021-03-04T17:14:09+00:00 Jeff Epler jepler@unpythonic.net 2021-03-04T15:29:01+00:00 urn:sha1:68ac14b3097291ba3c2f0c7edc61f93beebc783d 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. 2021-03-02T17:01:50+00:00 Dan Halbert halbert@halwitz.org 2021-03-02T17:01:50+00:00 urn:sha1:f41fb6fafc1fad51154c476ddfe5aa6772d08d8d copyediting 2021-02-26T23:07:30+00:00 Jonny Bergdahl bergdahl@users.noreply.github.com 2021-02-26T23:07:30+00:00 urn:sha1:f7eac46c7814a8c8cdc1f8841d3087fcf0a0632c Changed woring to use max instead 2021-02-23T23:50:00+00:00 Scott Shawcroft scott@tannewt.org 2021-02-23T23:50:00+00:00 urn:sha1:360475e26618cba98522d5dd86d0051d3a296fb3 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
