I have a myRio and wish to design a VCO ie a direct digital synthesis sine wave (doesn't need to be more than a few hundred Hz +/- 10Hz say) who's frequency is controlled by dc. I looked at the sine wave generator on the FPGA but it is an express VI and you cannot get access to it to add code. Any suggestions what to use? I even thought of using the processor but I can't get access to the D to A except via the FPGA or am I missing something here. Do I generate on the processor and then FIFO the data back to the FPGA to get the data out to the real world?
