Dear Arnaud,
Thanks for your help, I was able to load whatever samples I wanted by modifying the project. For the last few days I've been looking to try to constantly stream samples into the DAC, and from the ADC, as apposed to now where, as far as I understand it, the program loads bursts of 65536 samples onto the FPGA and then the firmware on it cycles through these samples indefinitely to produce the waveform. Firstly, is my understanding of what is going on in the FPGA/DAC correct and secondly, do you know how I could get samples to continuously stream in/out through the ethernet port? We do not need to load samples in at a very high speed, something around 20 MHz is fine and I think that is supported by ethernet.
Thank you very much for your help,
Best,
Varun
