hi,
i wonder if it's possible to use TWO max7219 to control a matrix of 64 BI-color leds.
the bicolor leds share the same anode and have different cathodes.
my first thought was to control red with one max7219 and green with the other.
a different approach would be to to have each max7219 control a matrix of 4x8 bicolor leds.
has anyone tried something like this? or do you know of a bicolor version that is easily available in europe and that you can recommend?
thanks for the code so far. i speant 2 full days writing my own. but now i can save another 2 days for cleaning it up
