You could do that (as long as your parallel port isn't full of Mesa card) but it makes a lot more sense to do the PWM generation on the Mesa card too. (Mhz rather than kHz PWM capability) Bear in mind that the Mesa (or similar) cards have a lot more pins with more (and documented) current drive capability than a parallel port too. -- atp ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
