There is a difference if nested interrupts with priority is available otherwise CPU rarely make any practical difference then programming although available execution power may be a limitation. Peripherals may make a difference but it is usually not to hard to move code to another device with different peripherals. ------------------------------------------------------------------------------ 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
