neo matrix library

Hi guys im currently working on a project that uses an 8 by 8 neo pixel matrix. I cant find too much support for the libray online. How would i go about programming a little smiley face :) using the libray. or how would i got about lighting specific LEDs on the neo pixel matrix

how would i got about lighting specific LEDs on the neo pixel matrix

The software sends out data representing the brightness of each LED. The first data that gets sent out is the one that goes to the furthest LED.

How would i go about programming a little smiley face

Draw on paper where the LEDs are in spacial relation to each other. Then mark the LEDs you want to be on to make your smiley. Then work out the data you need to send to make those LEDs light up.
