ZC706+DAQ2 DMA Control

Hi I'm using ZC706 + DAQ2 with no-os implementation. I am trying to capture ADC data using a PWM control wave (start storing the data to ddr3 at rising edge of the control signal and then read back after collecting certain number of samples and repeat). So what's the best way of doing this? I know that the DMA transfer is initiated through dma_xfer_req, but I'm not sure if using something like an AND gate will work.

 

Thanks!
