A while back I posted a video showing how to control 8x8 dot matrix without any aditional drivers and libraries.
I created few scetches. One for lighting all LEDs of the matrix one by one, one for displaying the simple bitmap and one for scrolling the sample text.
Generally I had some fun with multiplexing.
I promised a follow up video which would show how to control those matrixes with MAX7219 Driver And here it is.
The full tutorial can be found here:
