function state = RPI_DigitalIn(pin)
// Function to read current state on digital pins.
//
// Calling Sequence
// state = RPI_DigitalIn(pin)
//
// Parameters
// pin : pin of RPi to be used
// state : current state of the pin (0 -> LOW, 1 -> HIGH)
//
// Description
// This fucntion is used for reading the current state on gpio pins of RPi. 'RPI_DigitalSetup' function must be called before this for setting up pin as input. 'pin' must be specified from list given. 'state' specifies the input state (0 -> Low, 1-> High)
// Examples
// RPI_DigitalIn(RPI_GPIO_P1_03) //Reads the state of pin 3 of header P1.
//
