ADC using DMA

Question asked by sanchez.damaso on Apr 10, 2015

I'm using a stm32f429 running at 144MHz and I wanted to implement a periodic two-channel adc conversion. I need to make the conversions on a 1us period and I'm considering in using a dma adc conversion.
I know how to make a continuous conversion using dma, but not a periodic one.
If the conversion period was longer, I would use a timer interrupt to make a one-shot dma conversion, but been it a 1us period, I doubt the system can work at such speed.
Can someone please give me some insight on the matter?
