Re: Interfacing xadc to the zedboard

A good place for you to start is with the XADC user guide

http://www.xilinx.com/support/documentation/user_guides/ug480_7Series_XADC.pdf

 

This will detail the XADC, it's operating modes and the analog inputs. 

 

Next it would make sense to look at this XAPP

http://www.xilinx.com/support/documentation/application_notes/xapp795-driving-xadc.pdf

It will detail a proper way to acquire the signals at the analog input. 

 

The next step would be to look closely at what is available for the Zedboard so you can connect the signal to the XADC.
