Need some help with Led matrix

Using Arduino LEDs and Multiplexing
1

Hi. I'm trying to display on multiple led matrixes (6 8x8 and 2 8x32) connected in a line using an arduino nano but i have nearly no idea how to begin with the programming. I kinda understand how the pins work now but i have trouble understanding how i could control each 8x8 section and make them display what I want. Everywhere i look on the internet they only use 1 8x8 section and there is no explanation how to display on multiple.

Hardware to drive LEDs.

Already built.

Software to drive the hardware.

I'll check the library out once I'm home. Thank you

If you want control of each pixel in a specific panel, this a function call using the following library...

lc.setLed(0, 2, 1, state); // panel 0, x = 2, y = 1, ON/OFF

Some examples:
