+// Function to read the state of the gpio pin
+//
+// Calling Sequence
+//     u8RPI_DigitalIn(pin)
+//
+// Parameters
+//     pin : pin of RPi to be read
+//     
+// Returns
+//	   state: Current state of the specified gpio pin
+//
+// Description
+//     There are few pins available on RPi as Gpio or digital i/o. These pins can be used as digital output or input. Using this function, current state (low/high) of any gpio pin can be read. 'pin' name must be provided from list provided. Please refer '' for complete list of pins. 'state' can be 0 or 1 depending upon state of the pin (Low/High). RPI_DigitalSetup with appropriate arguments must be called before using this function.
+// Examples
+//     u8RPI_DigitalIn(RPI_GPIO_P1_03,1) //Returns the state of pin 3 of header P1
+//
