I'm using ZedBoard + fmcomms2 + no-OS-master;As a beginner, I have debugged the reference project. There are two kinds of data sent by DDS or DAC_DMA (sine_lut), but now I send my own data by DAC_DMA (I_data\Q_data ---from matlab), the spectrum observed on the spectrum analyzeris is same as that the previous spectrum when I sent sine_lut by DAC_DMA.
I have defined "DAC_DMA" and used "DATA_SEL_DMA".SO where is the fault? And how can I send my own data correctly (Array: I_data\Q_data)?What should I do and how to do?
The steps I have taken：
1、 I defined DAC_DMA
2、I selected "DATA_SEL_DMA" as the input to function “dac_init”（dac_init(ad9361_phy, DATA_SEL_DMA, 1); ）
3、I defined my own data: array I_lut and Q_lut
4、Assign values to data_i and data_q.
And I put a few screenshots about my work.
I am looking forward to your help.thank you!
