I would like to interface a 8x8 leds matrix such as this one:
Firstly i checked the arduino tutorials and playground, as well as the forum. I saw a lot ofinformation, but i have the 75HC595 shift registers and not the max7221 or max7219.
When i saw something about how to wire the 74HC595 it is just only for monocrome or RGB matrixes... but not for RG. So i am a little bit lost about how o wire them to arduino duemilanove.
Any idea about how to wire a circuit to run this matrix by 74HC595??

If you have a circuit for RGB then just miss one part out and use an RG.
Yeah! it could be an option, but i don´t see the circuit... so i just only know that they use this shift register, but i don`'t know how anyway...
Or the showed led matrix have different number of pins, or... in any case, i can´t apply it to my arduino and matrix....
In that case use this:-
And have a common row feed but separate columns.
I will read carefully what you saw there and try to learn how to apply it to my matrix.
