How did you compile the code? (jn lp mode or hp mode) How did you supply inputs to the ADC channels? (please provide connection details) Are you using excitation channels to energize these ADC inputs? Giri

I'm using the source code 'C:\Crossbow\cygwin\opt\MoteWorks\apps\xmesh\XMeshBase' for the base node, and 'C:\Crossbow\cygwin\opt\MoteWorks\apps\xmesh\XMDA320' for the node #1. AND I didn't change any code. when i connect a MDA320(whose analoy channel connect to nothing) to the micaz, i got the ADC0,ADC1,ADC2,ADC3's data in MoteView, which are all around 1.70V. but when i connected four different analog singal(0.8V,1.2V,1.8V,2.2V) to ADC0-ADC3, the all data i got is near to zero. I didn't change any code. I am very puzzled about this. I hope that i can get the siganl 0.8V in the MoteView if i have connected that analog siganl to the ADC channel. Thank you very much!
