Lenny, Thanks for dropping by!! yes I am aware of the thing you are saying, actually your post (& code ) was the post because of which I decicded to use BBB and PRU for my purpose :-)
but to be frank, Assembly coding is bit intimidating for me right now, I invested almost 20 days to study PRU reference guide but couldnt start a bit!! another bummer was how to transfer data from PRU to userspace, If you can guide me precisely, I will be more than happy to walk on that path..!! :-) On Saturday, October 3, 2015 at 8:36:13 PM UTC+5:30, Lenny wrote: > > here is a thread talking about it, in which you can also find my code > example among other info. > > > https://groups.google.com/forum/#!searchin/beagleboard/fast$20ADC/beagleboard/3AFiCNtxGis/RiWxHDiOWnMJ > > On Saturday, October 3, 2015 at 5:01:26 PM UTC+2, Lenny wrote: >> >> Hi Rathin, >> just to let you know: The BBB ADC's can sample at 1.6 MHz.
