What is the sampling rate you want to achieve? Isn't it possible to do this with standard McSPI peripheral? I don't think there are ready examples of doing this with PRU.

In reply to Biser Gatchev-XID:
Thanks for your help. I would like to achieve a minimum sampling rate of 1 MSPS, and if possible in a "real-time" way, i.e. the time between two samples should always be the same.
Is it possible with standard McSPI peripheral? If so, it would make things easier I think. Do you have a link to relevant online resources to get me started?
In reply to Baptiste Pierrat:
The McSPI can go up to 48MHz clock, however I don't think that what you want to achieve will be possible under Linux. You might want to check the Starterware package, which is an OS-less environment: http://processors.wiki.ti.com/index.php/StarterWare
