    PSoC5LP DMA interrupt Problem

    ferhatyol_2020106

      Hi 

         

      I need to transfer parallel data using DMA and GPIO. But I have a problem. 

         

      I looked at the examples given here.

      This application is working. I tried it on my CY8KIT-50 Psoc5lp Development kit. 

         

      In the given application, the interrupt occurs after all the data has been transferred. But I need to generate a clock signal after each transfer data of the DMA. For example, If the DMA transfer size is 1024 Bytes, I need 1024 interrupt. Because I need to generate a clock signal after writing data to the GPIO.

         

      How can I do that?

         

      Thanks.
