I don't know if any of the FPGAs have an analogue output. Generally they output a PWM which is converted to voltage by a filter, so there is a bit of a speed limit there. Some cards use an actual digital potentiometer or D to A, but those are typically driven by smart-serial and to would pretty much have to be at servo-thread rate via HAL. -- 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, 1912 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
