Analog channel interfacing through XADC in Zedboard

[jayasankarvn]

I recently purchased Zedboard from Digilent. I have one doubt regarding XADC in it. If I use Vp/Vn or vauxp0/vauxn0 or vauxp8/vauxn8, the external analog signals can be connected through the pins in xadc header. If I want to extend the auxiliary channel number, where do i connect the analog signals ? Should I use an fmc break out board to access those ? Or can I convert the Pmod I/Os to auxiliary channels ? Please do reply.

Hi @jayasankarvn,

Yes, you will need to use an FMC breakout board to access the rest of the xadc signals. On page 9 of the schematic here  has Bank 35 that shows which pins on the FMC are tied to the XADC.

cheers,
