What am I doing wrong ?

Hi, Malc

Don't you think a simple triangle slow wave generator based upon a 555 or a twin AOP could perfectly do the job ???

Note a simple bulb lamp could also do all the job itsef ... with a rectangular wave input.

Quite possibly, however that wouldn't improve my understanding of PBP

May be intended for some stop light for road/rail crossing, I presume ???

Errr.. actually you don't want to know... Oh well all right..

A friend wants to model the Tardis from the BBC series Dr Who... and it has a slow pulsing light on top..... me and my big mouth offered to help, and like I said it works fine on a 16F628a, but I just need to port it to a 12F675
