Another alternative is a digital potentiometer: https://www.ebay.co.uk/itm/X9C104-Digital-Potentiometer-Module-100-Potentiometers-For-Arduino-/401571443553 These use a step-dir interface. But... looking at the data sheet they only withstand a few V between Vss and the potentiometer pins, so they are not much use for KBIC controllers. -- 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 Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
