Create an IRGB helper function to construct a 4 byte LED Frame.

Parameters:

Definition at line 48 of file APA102a.h.

void Repaint ( )

Repaint the Strip Sends to the Buffer to the Strip.

Parameters:

none

Definition at line 25 of file APA102a.cpp.

Set the Buffer.

Parameters:

buffer[]	: a buffer of unsigned integers (4 bytes) RowsStride in size
Rows	: Number of Rows
Cols	: Number of Columns
Stride	: The actual number of columns (useful for data alignment)
Offset	: The offset into a row
ZigZag	: A boolean, do we alternate count up/ count down per row?
Wrap	: A boolean, do we wrap if (Offset+Cols) > Stride? (handy for scrolling messages)
