PlatformIO: Arduino for Raspberry Pi Pico (RP2040) with Programmable IO (PIO) support

This is a set of files that sets up an environment that will compile an Arduino project and assemble Programmable IO (PIO) scripts into C++ header files for inclusion in Arduino source files.

I made these notes in October 2024 after spending a lot of time researching how to make PlatformIO, Arduino, and PIO work together.

(Not yet fully tested.)

Prerequisites

Deltaprintr Firmware HOWTO

These instructions are for the original plywood-frame Deltaprintr from the 2013 Kickstarter campaign or sold on the website before the release of the Delta Go. The Kickstarter campaign ran in 2013 with printer rewards for $500 pledges, and printers were delivered in 2015. They use a custom variant of the Azteeg X3 controller board. There was a vibrant community for a couple of years on the forums, designing mods and improvements, and sorting out each other's print issues. I've had mine working quite well for years.

This comprises several firmware-related forum posts; my original firmware HOWTO, my fix for stuttering movement, and Ian Brennan's [experimentation](http://forums.deltaprintr.com/index

	# Script to add/delete users from Moonraker's LMDB database.
	# This would've been so much less painful if they'd used SQLite.
	# But good news! They're switching to SQLite soon (posted Dec 2023):

	// Quick shortcut for shortcomings in `gulp.task` API:
	// 1. `gulp.task` doesn't accept a description, has to be a prop on the function.
	// 2. Since description has to be on the task function, it's harder to add a
	// description to tasks whose functions were created by a helper (e.g.
	// `gulp.series` or `gulp.parallel`) since you didn't define the functions
	// they return.
