    [4M] Memory -> GPIO Port with DMA [Solved]




      I'm doing a silly project where i have an array of random numbers and i would like to transfer each element of the array to the GPIO Port 1 with DMA, each transfer must be done when the user on-board button is pressed.


      The DMA component is configured to transfer Byte -> Word, incrementing the source one element after each transfer.


      I thought the following line will make the project run, but it seems like it does not:


      DMA_Start((void *)array, (void *)Pins_DR);


      Any thoughts?




      I'm mostly new to PSoC 4 DMA so maybe there's a obvious mistake. I'm using the CY8CKIT-043 board.


      Project is attached. thanks in advance
