The most expedient solution might be an Arduino (you can buy a Nano for £5 on eBay, and that's a cheap way to get a uC and programming interface on a board) There is an interface to HAL for Arduino via USB, but that isn't real-time so might not work for your application. Reading one PWM frequency and outputting another is definitely possible, I have even done it once to bypass a misunderstanding between suppliers at work. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
