I am making a Wii portable and need to construct a circuit capable of converting analog stick signals into D-Pad signals when a trigger button is depressed. The reason: I want to use a giant 3W speaker and a 5.6" LCD and don't have any room on the front of the portable for a D-pad.
The idea is that since a GameCube controller is set up to where you almost never have to press the d-pad while moving the analog stick, one could potentially use the analog stick as the D-pad. I just need to figure out how to make the joystick-to-D-pad circuit only turn on when I press a trigger button. (Which will look like a Z-button except on the right.) Any ideas on a circuit?
