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.)

# moonraker-users.py (by @mildmojo)
#
# 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):
# https://github.com/Arksine/moonraker/issues/781#issuecomment-1871333293
#
# Run this script with /home/pi/moonraker-env/bin/python. For a
# Klipper deployment installed with KIAUH, something like:
#   ~/moonraker-env/bin/python moonraker-users.py --create /home/pi/printer_data/database my_user my_password

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

  Implements the dark frame subtraction pipeline using ImageMagick described here:

  It's very slow.

// 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.
