DMA Trigger via input GPIO Pin

Hirbel Hannes

Hi,

is it possible to start a DMA transaction by a falling edge on a GPIO pin?

I used the EXTI configuration for this input pin and in the EXTI-ISR i can trigger the DMA.
But i think this is not a really good solution, because of a trigger-signal of 9 - 18 MHz.
So i want to trigger the DMA by the hardware.

Greetings Hirbel
