Hi
I'm building a huge led matrix out of bi colour leds with a common cathode. So there are two anodes, one for each colour and a gnd pin. I'm confused as to which chip to buy. Is it not possible to buy an led driver that would drive 144 leds arranged into sixteen 3*3 matrix. I was under the impression an led driver, is basically a power source for leds. Ideally this should be either soic or pdip. If possible I would like invididual control to every single led as well (not absolutely nesscessary but fun to play with )
