True, I had a choice between MAX7219 and CD4159. At that time I was looking at something that I could connect 100% myself (no help from outside
) and rapidly, so I chose CD4159 for simplicity and datasheet clarity.
Oh yeah, as far as I understood MAX7219 is best suited for common cathodes, meaning I had to do some stuff (advised at forums, like inverting currents and many more I do not understand at all) to get it working with common anode matrices.
