Kaleidoscope-LED-AlphaSquare

An alphabet for your per-key LEDs, AlphaSquare provides a way to display 4x4 "pixel" symbols on your keyboard. With this building block, one can build some sweet animations, or just show off - the possibilities are almost endless!

Using the plugin

To use the plugin, one needs to include the header, and one way or another, call the display method.

#include <Kaleidoscope.h>
#include <Kaleidoscope-LED-AlphaSquare.h>

void setup () {
  Kaleidoscope.setup ();

  USE_PLUGINS (&AlphaSquare);
  
  AlphaSquare.display (Key_A);
}

Plugin methods

The plugin provides the AlphaSquare object, which has the following methods:

`.display(key)`

`.display(key, row, col)`

`.display(key, col)`

`.display(key, row, col, color)`

Display the symbol for key at the given row or column, with pixels set to the specified color. If row is omitted, the first row - 0 is assumed. If the column is omitted too, then the third - 2 - column is used by default. If the color is omitted, the plugin will use the global .color property.

The plugin can display the English alphabet, and the numbers from 0 to 9.

`.display(symbol)`

`.display(symbol, row, col)`

`.display(symbol, col)`

`.display(symbol, row, col, color)`

Almost the same as the previous function, but instead of a key, it expects a 4x4 bitmap.

`.clear(key)`, `.clear(symbol)`

`.clear(key, col)`, `.clear(symbol, col)`

`.clear(key, col, row)`, `.clear(symbol, col, row)`

Just like the .display() counterparts, except these clear the symbol, by turning the LED pixels it is made up from, off.

`.color`

The color to use to draw the pixels.

Not a method itself, but a changeable value.

Defaults to { 0x80, 0x80, 0x80 }.

Plugin helpers

`SYM4x4(...)`

A helper macro, which can be used to set up custom bitmaps. It expects 16 values, a 4x4 square of zeroes and ones. Zeroes are transparent pixels, ones will be colored.
