hej,
i guess the 4x8 biocolour version could work, the problem is just that the code for the max7219 (posted by massimo) is just working for one max7219, if you want to use more then one max7219 you have to change the code,
for example: you have to change the max7219_init(); because this version is just talking to the first guy, you should have a look in the data sheet, im not so good in explaining this stuff, but right now im trying a vesion with two max7219, if will post it if it is working, tomorrow,...
ha de bra
