I was making an electrical schematic for my HackPad, and I ran into an issue when connecting all the components to the controller, as there are not enough pins.
I have: dispaly(2 pins), 3x3 matrix(6 pins), rgb leds(1 pin) and 2 rotary encoders(4 pins, the buttons are in the matrix).
The controler has 11 data pins but I need 13.
Can someone help?
