Hi all !

 

I read a couple of article about DMA so I got the main idea but I'm still confused about the application possibilities of DMA.

I want to collect high speed data (up to 100 Mb/s) from a GPIO pin and send them to an external RAM.

GPIO -> DMA -> RAM

Then i need to get access to these data from my uP to do some computing.

RAM -> uP

Is it possible, if yes then how ?

Thanks in advance for your reply !
