I need input data from GPIO with external strobe (2000 samples; strobe is about 10 Mhz). But speed of processor it not enough.
Can I do it with DMA?
I have found many samples, but all of them use external signal as trigger for start DMA.
Does it possible use external signal as DMA strobe (move data word from GPIO to memory for each rising of strobe signal)?
