Best way to use Prop 2 pins for multi-color LEDs
![Invent-O-Doc](https://forums.parallax.com/uploads/userpics/096/nZ43CVNLJ1E1P.jpg)
I'm thinking that the large number of pins might make the prop2 a good chip to drive an 8x8 RGB LED Matrix display, using 3 sets of 8 pins for rows (one each R, G and
and using a high current sink type serial shift register for ground.
What do you think would be the best approach to adjust the brightness of individual LEDS colors?
1) Use the DAC function to vary voltage
2) Use counters to achieve a PWM effect
3) Other technique I haven't thought of/

The P1 can drive a single color 128x32 pinball DMD display using an all shift registers like setup and get a few shades on it.

But, would be much better with Prop2.
The extra memory, faster processor and more pins will allow one to do a lot more....
