The Library of course uses the regular orientation. Consider this:
|
||
|
|
|
||
|
|
matrix.drawRect(x,y, sizeX, sizeY, matrix.Color888(255,255,255));
|
||
|
|
|
||
|
|
x,y are the starting co-ordinates starting from top-left
|
||
|
|
|
||
|
|
sizeX, sizeY will be the size of the rectangle we want to draw.
|
||
|
|
|
||
|
|
Everything is in pixel (px) logically 1px == 1LED
|
||
|
|
|
||
|
|
The ColorXXX() functions are used to define the color "spectrum"
|
||
|
|
|
||
|
|
Color333() - 3bit color representation
|
||
|
|
Color444() - 4bit color representation
|
||
|
|
Color888() - 8bit color representation
|
||
|
|
|

|
|
To simulate a grayscale is pretty difficult and needs some hacking:

We have 20 windows at our disposal.

I chose the cheapeast and dirties path possible for the PoC and the following map gives you an overview of the addressing of the windows on the mock-up:
