AVR utils library
=================
This is my ever-evolving library (not only) for AVR programming.
When I'm done with a project, I copy the current library to the project, so it doesn't break when I do further improvements.
Each library file contains a large comment block explaining it's function.

as_output(LED);

pullup_on(SW1);
toggle_pin(LED);

- The macros io2XXX() can be used to get literal name of register associated with the pin.
- io2n() provides pin number.
- The XXX_aux() macros are internal and should not be used elsewhere.
- The io_pack() macro is used to pass pin (io) to other macro without expanding it.

Utils for driving a WS28xx (tested on WS2812B) RGB LED strips.
It's implemented as macros to avoid overhead when passing values, and to
enable driving multiple strips at once.
To avoid bloating your code, try to reduce the number of invocations -
compute color and then send it.
[IMPORTANT]
Some seemingly random influences can ruin the communication.
If you have enough memory, consider preparing the colors in array,
and sending this array using one of the "ws_send_XXX_array" macros.
