+function adc_result = AVRReadADC(channel)
+// Function to get voltage on analog pin on AVR
+//
+// Calling Sequence
+//     u8AVRReadADCs(channel)
+//
+// Parameters
+//     channel 	: Select which channel is to be read. Values from 0-7 select one of the pins ADC0-ADC7. For other possible channel values refer datasheet
+//
+// Description
+//     This function returns digital value for present on adc pins. 'channel' 
+//     selects which of the ADC0-ADC7 is to be used for reading analog value.
+//     Apart from reading just ADC0-ADC7 other it can also read differential 
+//     voltages between some pins. For channel values for those options, please 
+//     refer datasheet.      
+//
+// This is curretly dummy function. It provides no functionality but is required 
+// for providing support for generating C code for AVR.
+//
+// Examples
+//     adc_result = u8AVRReadADC(0)   //Read ADC0
+// Authors
+//     Siddhesh Wani
+//     Ashish Kamble
