Detailed Description

This class defines a type that can encode a GPIO pin as a variable. Read the section on GPIO Pin Variables to understand how to use this class.

There are also three macros that you need to create vaiables of type GpioPinVariable: makeGpioVarFromGpioPin(), makeGpioVarFromGpioPinAnalog(), and makeGpioVarFromGpioPinPwm(). These are used like this:

GpioPinVariable  pinA( makeGpioVarFromGpioPin( pPin10 ) );
GpioPinVariable  pinB( makeGpioVarFromGpioPinAnalog( pPinA01 ) );
GpioPinVariable  pinC = makeGpioVarFromGpioPinPwm( pPin03 );

GpioPinVariable pinArray[3];
pinArray[0] = pinA;
pinArray[1] = pinB;
pinArray[2] = makeGpioVarFromGpioPin( pPin07 );

Once you've done this, these variables can be assign and passed to functions as needed. To use these GPIO pin variables, there are special function analogs of the GPIO pin manipulation macros. These have the same names as the GPIO pin manipulation macros, except with a "V" appended.
