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 2021-02-06T15:54:25+00:00 Jason Nichols jason@jsun.biz 2021-02-06T15:54:25+00:00 urn:sha1:ae262cde55669c354fa2422097581b4ac4afaf88 2021-01-21T18:17:40+00:00 Scott Shawcroft scott@tannewt.org 2021-01-21T18:17:40+00:00 urn:sha1:b47fd08b20f0917874461dc1a0e201e7cc7e55db 2021-01-21T07:33:00+00:00 Scott Shawcroft scott@tannewt.org 2021-01-21T07:33:00+00:00 urn:sha1:b0f7fd933f82c3d8d0dac63978a622114019468c 2021-01-21T03:16:56+00:00 Scott Shawcroft scott@tannewt.org 2021-01-21T00:47:18+00:00 urn:sha1:733094aead6e84b42da54655b2b0a5d0dbd1a503 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
