Re: Two tone sample on dma_setup or dds_setup for FMCOMMS1

Thank you Dragos,

I'm successful display the two tone spectrum by setting desire f1 and f2.

Now its clear for me on dds_setup function.

Then I use dac_dma_setup by default code in test.c and observe the spectrum output. As a result I got this weird spectrum output. My expectation is just one peak that represent sine/cosine look up table. Do you have any comment on it? thanks
