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.

/*
Some useful utilities for RGB color manipulation
The XXXc macros don't use cast, so they can be used in array initializers.
xrgb ... 3-byte true-color RGB (8 bits per component)
rgbXX ... XX-bit color value, with equal nr of bits per component
XX_r (_g, _b) ... extract component from the color, and convert it to 0..255

/**
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.
