Hi @thokalanaresh99 

UG480 - XADC User Guide is a great place to start. (designs)

XAPP1183 describes how the XADC acquires analog data using its dedicated Vp/Vn analog input (designs)


Cheers

Re: xadc

Dxp/n is a temp diode. It's not connected to the XADC...

Re: xadc

Hi @thokalanaresh99 

When not used to access the thermal diodes, they should be tied to GND.

Dxp and Dxn pins can be grounded okk.

How to read the data from Vp and Vn throgh AXi-lite interface . for the how to make the dtsi file and how to get data in the kernal.

i am litle bit conficuing with the Vp and Vn use i don't know how to use this two pins as external .

 i take the XADC-wizard ip and i take Vp and Vn as external and  i assign the pin location for the Vp and Vn and i create the HDF know how to get the data in the kernal while booting the device.
