* Fix code formatting
* Use CountDown instead of Delay
* Add the Pimoroni Plasma 2040 board
This PR adds the board support package and a simple example.
The example just blinks the on-board RGB LED.
An example should be added for using the board to control an LED strip.
This should probably use smart-leds with the associated PIO driver.
An example or functionality should be added for the current sensor.
* Rename LED data line from dat to data to match schematic
* Add an example for driving WS2812 LEDs
This is pretty much a copy-paste of the awesome pico_ws2812_led example.
* Remove reference in README to rp-pico
* Remove reference to pico board clock speed
I have removed this in the Plasma 2040 repository and where I copied it from, tiny2040_blinky.
* Remove redundant namespace
* Add self-reference in README to the current board's GitHub README
Fix the erroneous link in the pimoroni-tiny2040 README from which I copied.
Using the full module structure generated by the intrinsics macro
interacts oddly with inlining on some optimization levels, causing
a duplicate identical function body to be generated. This doesn't
affect performance, but it wastes space, so just declare the alias
directly which seems to cause the symbol to be aliased as it should
be.
* add example of synchronized PIOs
* Synchronize state machines using WAIT IRQ instruction
* Use "irq wait 0" instead of "wait 1 irq 0"
This way, the initial value of the interrupt flag doesn't matter
* Start state machines synchronized without IRQ WAIT instruction
* Improve API

* Add an rp2040 specific #[entry] macro.
This macro extends the one from cortex-m-rt by code to unlock
all spinlocks on boot.
* Idiomatic pointer arithmetic
Apply suggestion by @9names, improving address calculations.
(This doesn't change the generated code at opt levels 2 or "z".)
