Earle F. Philhower, III 8c3170596f Deduplicate SPI and SoftwareSPI routines (#2779) 2025-01-28 12:47:13 -08:00
Earle F. Philhower, III acf81f426c Add PIO-based SoftwareSPI enabling SPI on any pins (#2778)
* Add PIO-based SoftwareSPI enabling SPI on any pins

The Raspberry Pi team has a working PIO-based SPI interface.  Wrap it
to work like a hardware SPI interface, allowing SPI on any pin
combination.

Tested reading and writing an SD card using unmodified SD library.

* Add W5500 example

Good for testing, shows non-contiguous pin outs.

Earle F. Philhower, III 84826935a9 Don't set SDFAT_FILE_TYPE, default is OK (#2773)
* Don't set SDFAT_FILE_TYPE, default is OK

Fixes #2772

No need to set SDFAT_FILE_TYPE=3 as that is the defaulr value with upstream
SdFat.  Remove it from platform.txt and platform.io build.

* Codespell got all techy

----------------------
For RP2350 based boards, this controls what chip-select (also called: slave-select / SS) pin to use when wanting to talk to the PSRAM chip.
Note that it's not needed to set this with a board that is known to have a PSRAM chip on-board, such as a "Sparkfun Thing Plus 2350". The ``pins_arduino.h`` of that variant already has the correct definition.

Boot2 is the second stage bootloader and predominantly used on the RP2040.
Its main purpose is to configure the communication with the Flash at the highest, safest speed it can.
All known boards have their correct value already configured. However, when choosing ``board = generic``,
you can freely configure the Boot2 to be for a different flash.

Similar to ``SoftwareSerial``, ``SoftwareSPI`` creates a PIO based SPI interface that
can be used in the same manner as the hardware SPI devices. The constructor takes the
pins desired, which can be any GPIO pins with the rule that if hardware CS is used then
it must be on pin ``SCK + 1``. Construct a ``SoftwareSPI`` object in your code as

; SPI with Chip Select
; -----------------------------------------------------------------------------
;
; For your amusement, here are some SPI programs with an automatic chip select
; (asserted once data appears in TX FIFO, deasserts when FIFO bottoms out, has
; a nice front/back porch).
;
; The number of bits per FIFO entry is configured via the Y register
; and the autopush/pull threshold. From 2 to 32 bits.
;
; Pin assignments:
; - SCK is side-set bit 0
; - CSn is side-set bit 1
; - MOSI is OUT bit 0 (host-to-device)
; - MISO is IN bit 0 (device-to-host)
;
; This program only supports one chip select -- use GPIO if more are needed
;
; Provide a variation for each possibility of CPHA; for CPOL we can just
; invert SCK in the IO muxing controls (downstream from PIO)
; CPHA=0: data is captured on the leading edge of each SCK pulse (including
; the first pulse), and transitions on the trailing edge
