Re: Help please, problems reading analog samples

More on this:

I have been making some tests with a pair of sensors.

When I select AREF_GROUND and one channel more of the due channel (i.e. if I 
use channel 9 I chose channel 8 for read, if I use channel 15 y read from 14 
channel) the read becomes stable (+-0.5mV) but when one sensor changes I see 
the result in both channels. If I select AREF_DIFF I read nothing from those 
channels.

If I select the right channel (use and read from the same channel) then the 
signal is unstable (+-150mV) and changes in sensors also spread among both 
channels.

I am using Advantech PCI1710HG

Very desesperated, please need help!
