Thanks for the help ... However I was still not able to figure out to which component I should wire the file voltageC.nc Also, how will I be able to take out readings specifically from ADC1, ADC2 and ADC3. I saw the files and the defined constants in Atm128Adc.h...but where do I include the file and how do I pass on the values of the constants.
PLEASE help me on the intended use of the components ArbitrateRead, MicaBus. I guess wirig MicaBus.Adc1 will give me the readings of ADC1 Thanking you for the same ...
