+// Function to change the output state of the gpio pin
+//
+// Calling Sequence
+//     u8RPI_DigitalOuts(pin,state)
+//
+// Parameters
+//     pin : pin of RPi to be used 
+//     state : desired output state for pin (0 -> LOW, 1 -> HIGH)
+//
+// Description
+//     There are few pins available on RPi as Gpio or digital i/o. These pins can be used as digital output or input. 'Pin' name must be provided from list provided. Please refer '' for complete list of pins. 'state' can be 0 or 1 depending upon desired output (Low/High). RPI_DigitalSetup with appropriate arguments must be called before using this function.
+// Examples
+//     u8RPI_DigitalOuts(RPI_GPIO_P1_03,1) //Sets pin 3 of header P1 as 'high' output
+//
