XADC on the Zybo

[General Neyland]

OK, I've tried everything for a week. I simply cannot get any data out of my external sensors using the XADC. 

Can someone *please* give me some help. I'll attach my .v file, my .xdc file, and my IP file.

You can ignore the LEDs being named in the constraints file. I was just playing around with them trying to get them to light up if I got any data come in the data in line.

I had measured_aux0, measured_aux1, measured_aux2, and CHANNEL[4:0] in my module files, but it kept telling me there were not enough ports, so I took them out, and placed them as wires, etc.

Maybe that is part of the problem? It even wanted me to place 'reset' in the .xdc file for some reason. 

Anyway, I'm worried that my .xdc file might be the problem.

Thank you in advance for any help.

Were you able to run successfully C code for the XADC? This case was covered on this forum here  This test would allow to rule out most of possible configuration mistakes.

Personally, I can't help you with Verilog, I am not profficient.

Thank you. I will test that out. I have never messed with SDK, so I'm downloading it now.

Zynq combination of processors and FPGA increases productivity substantially. If you didn't use new SDK be patient and it's worth it.

Hi @General Neyland,

Here is a good demo using the XADC for the Zybo. Here is the tutorial that goes with the project. I would look at this project to help you with yours. Also you have reset as an input in your top_design so you would need to constrain that in your xdc file. 

cheers,

Jon
