Erik, your design is pure genius! I have the whole circuit packed inside of a DB-25 Hood with a 18 pin socket on the flat outside of the casing. Can anyone help me with this troubleshoot? The programmer would only work when I had a logic probe drawing power from ground and pin 14. Is this an added capacitance/resistance or both? A solution that worked turned out to be placing a .1uF cap between ground and MCLR????<-don't know what that has to do with the logic probe, but it worked. -()---()---()---()---()---()---()---()---()---()---()---()---()---()---()- Rolan Yang http://hertz.njit.edu/~rxy5310 Electrical Engineer rxy5310@hertz.njit.edu kyurius@tsb.weschke.com VR,ROBOTICS,FENCING,HACKING,INDUSTRIAL MUSIC,ART,EXPLOSIVES,INLINE SKATING THESE ARE A FEW OF MY FAVORITE THINGS. -()---()---()---()---()---()-----()-()---()---()---()---()---()---()---()- 4 out of 10 people are annoyed by ^ this.
