2021-03-31raspberypi: Allow mpconfigboard to override additional itemsJeff Epler
This allows more options to be overridden to 0 in an mpconfigboard.mk. Improved: * FRAMEBUFFERIO, FULL_BUILD, BITOPS, PWMIO, RGBMATRIX, OTARYIO, PULSEIO, WATCHDOG Still problematic (pull requests welcome): * RP2PIO & NEOPIXEL_WRITE, possibly only if a status neopixel is defined * BITBANGIO, possibly only if BUSIO is enabled * RTC Incidentally, with RP2PIO & NEOPIXEL_WRITE, BITBANGIO, and RTC re-enabled I get ``` 323956 bytes used, 720524 bytes free in flash firmware space out of 1044480 bytes (1020.0kB). 12072 bytes used, 250072 bytes free in ram for stack and heap out of 262144 bytes (256.0kB). ``` Closes #4515
2021-03-18Redo RP2040 flash settingsScott Shawcroft
This switches stage2 to C and uses Jinja to change the C code based on flash settings from https://github.com/adafruit/nvm.toml. It produces the fastest settings for the given set of external flashes. Flash size is no longer hard coded so switching flashes with similar capabilities but different sizes should *just work*. This PR also places "ITCM" code in RAM to save the XIP cache for code execution. Further optimization is possible. A blink code.py still requires a number of flash fetches every blink. Fixes #4041

Issue 4111 - Implement pulseio(pulsein) for RP2040
2021-03-10raspberrypi: Enable mp3 playbackJeff Epler
The rp2040 is _very_ marginal for mp3 playback, and currently sometimes triggers a bug that gives garbled audio output. However, it does work for some limited situations.

2021-03-05WIPrp2040: Implement IncrementalEncoderJeff Epler
Any two consecutive pins can be used for an IncrementalEncoder Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out. Performed filesystem operations at the same time to stress test it. The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

2021-02-23Implement audiobusio and enhance PIO for itScott Shawcroft
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

2021-02-18core: add bit_transpose functionJeff Epler
.. this version can only handle exactly 8 bits "across". The restriction may be relaxed in a future revision.

2021-02-12Enable protomatter on RP2040 buildsJeff Epler
Also found a race condition between timer_disable and redraw, which would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable or put a delay or print inside it. That's what pausing inside reconstruct fixes. So that the "right timer" can be chosen, `timer_allocate` now gets the `self` pointer. It's guaranteed at this point that the pin information is accurate, so you can e.g., find a PWM unit related to the pins themselves. This required touching each port to add the parameter even though it's unused everywhere but raspberrypi.

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
