What kind of signals there in this protocol?

If the Mesa firmware is open source I guess and it is a FPGA board there should be no problem to send packets with perfect timing. ------------------------------------------------------------------------------ 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
