I don't think that there is any need for re-coding. (and I doubt that it would be sensible to start sending JPG data to the FPGA). The Mesa cards already have a PWM generator and (presumably) it is clever enough to do the right thing when the duty-cycle changes. So, what is needed then is a realtime HAL component that reads image data and a userspace component to feed it that image data (no filesystem access for realtime components). The link I gave above has files to do part of this, it creates a private shared-memory region and loads image data into it where the realtime component can "see" it. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
