Would that transfer rate be possible with the DMA controller? I will have a look at FSMC and DCMI interfaces. BTW, is it possible to give a upper bound for the delay between DMA request and transfer? In my application the DMA transfer (copy one word to internal memory) must be completed...

I working on a project where I have to transfer data periodically over SPI in DMA mode. To avoid CPU intervention I want to trigger SPI DMA transfer using a Timer trigger. Please provide suggestions for this. Solved! Go to Solution.
