Now, I want to transmit the my custom data by KC705 and FMCOMMS2, using no-OS. My custom data consists of two columns as file .txt (a column for I signal, a column for Q signal) (I use Notepad++ software to open this file). To transmit these data, I insert them to line 63 of file dac_core.c (no-OS/dac_core.c at master · analogdevicesinc/no-OS · GitHub). and I choose transmit by DMA at line 463 of file main.c (no-OS/main.c at master · analogdevicesinc/no-OS · GitHub). Is it right? and Must I modify any core in .hdl project? Please help me to solve this problem.
