Is it Siemans that makes this chip? SOMEBODY does, few years ago I had the data sheet on it, intending on looking closer, but like all projects, took the back seat to others. But, somebody does make a VFD chip. Seems to me, that even Microchip was doing something with this (timeframe of like....4 years ago or more), the quick little blurb was talking of a 3 phase motor controller, and I even contacted the author on this one, and turns out the app was cancelled for some reason. Or at least was put on the back burner as well. Maybe someone else remembers this one. It was kinda obscure. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
