Hi everyone, 



I am using a modified version of the AD9361 HDL Reference Design combined with the No OS device driver. I already know how to write on the DAC memory and modify it. I would like to know how can i make sure that each set of samples is sent over the air only once, since in the No OS data is continuously sent regardless of updates. In other words i would like to send radio frames only once and it is not clear how the DAC sends it or if there is a flag that points out that a certain area of the DMA has already been transmitted.




Thank you for your attention,
