java.lang.Object | +--stamp.peripheral.hid.Joystick
This class provides an interface to standard analog joystick -- the kind used for PC games that plugs into a DB-15 connector (game port).
The joystick potentiometers are read using CPU.rcTime(). This code is written for the rcTime() capacitor to be connected to Vdd; the joystick pots connect between the pin/cap connection and Vss (ground).
Usage:
joystick controller = new joystick(CPU.pin0, CPU.pin1, CPU.pin1, CPU.pin2);
