RfSoc ZCU111 DAC implementation with Baremetal

Hello,

I have been trying to implement a DAC example in order to generate a sine waveform on DAC output.

The block diagram of my design is the following,BlockDiagram.png

The usp_rf_data_converter was set as following:img1.pngimg2.pngimg3.png

The dds_compiler block is responsible for generating the sine waveform. I think that it correctly generates the sine waveform, since I am able to obtain the exepected signal and see it on ILA. However, when I connect an oscilloscope to usp_rf_data_converter I only see a constant voltage instead of a sine wave. DDS_compiler block was set as following:

I was not able to attache the project's code on vivado 2019.1 because it is larger than the maximum allowed, although I can send by e-mail if anyone wants to try it. I attached the sdk main. I used the baremetal library.

If anyone has insight on this problem it would be greatly appreciated.

Re: RfSoc ZCU111 DAC implementation with Baremetal

Hi @marianaferreiraramos ,

Wanted to know if you got your this issue resolved ?? I am too facing a similar issue. When I try to execute the read_write example present in github (link:  https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/rfdc/examples/xrfdc_read_write_example.c) it executes fine, but I do not see any wave or output in my oscilloscope. Please let me know if you got this resolved and how.

Thanks,

V

Hi @vish.bh30 ,

I couldn't solve the issue yet. My code is in the following link:

Please check if you can execute it. With this sdk I am only able to see a constant output voltage instead of a sine wave, as you can see on ILA input.

If you have made any progress please let me know.
