Detailed Description

Yet Another Matrix Library.

Small library to be used with one or more 8x8 Dot Matrix displays.

Constructor & Destructor Documentation

Instantiates a new Neo class.

Parameters

displayCount	Number of 8x8 Matrix Display to use.
cs	The CS / LOAD pin number.
din	The DIN pin number if SPI not used, else not required.
clk	The CLK pin number if SPI not used, else not required.

void Neo::setBrightness ( uint8_t value )

Sets the display brightness.

Parameters

value Brightness intensity from 0 - 15

void Neo::append ( byte frame[8] )

Append a character frame to the internal display buffer.

Parameters

frame byte array of length 8.

Renders a character frame to a particular display position.

Parameters

disp	The position of the display to render the frame.
frame	byte array of length 8.

Renders a row of a display.

Parameters

disp	The position of the display to render.
row	The row index (Starts from 1).
data	A byte representing the state of the row.
