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?

Subject: [Tinyos-help] for help about MDA320


Hi:
  I'm using MDA 320, MICAz and MIB 520. 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!
