Hi!
Even if simple, I haven't been able to find an answer to my problem:
I have a sensor that I want to read through the XADC. I am working with Zedboard.
I have adapted the signal from the sensor with a resistor divider so that the amplitude of the signal is small enough.
My problem is that the signal is centered around 0V. It has both a positive part and a negative part.
As far as I have read, the XADC expects a signal from 0V to 1V in amplitude. Will this signal be a problem for it? Or beeing a differential signal I can assume that the DC component can be neglected?
This is, can I connect the signal as it is, or do I have to avoid connecting any negative voltage to the XADC?
Thanks in advance for your help!
