I'm trying to investigate the capabilities of the DMA, and as an example, I'm trying to trigger the DMA by using a push button GPIO configured as an input. The platform I'm using is the TWR-K60F120M. I've been trying to use the processor expert since it helps greatly with the initialization code.
I've attached some screenshots of my settings. I'm simply trying to detect a falling edge of the push button, and initiate a 32-bit memory transfer. Can anyone point me to what I might be doing wrong?
For what it's worth, I know I've gotten the input GPIO working. I previously had it generating an interrupt, and it was working perfectly. It is only since I've tried to generate a DMA request instead of an interrupt that I've had issues.
