Hello Peter,
Ive read your reply on the 16MHz PIC question and you wrote

Now am I very interseted in your last commentline, refering to code.

I've created a PIC-project named "OSD-tracking" wich can find a bright
spot in a "normal" PAL-television/video signal. Then is projects a croshair
on top of this video-signal, resulting in a futuristic (but cheap) object
tracking device. The only sensor needed is a camera. Now I know it sounds
complex but it is quite simple (realy). The only thing is that my OSD
(On Screen Display as visible on monitor or TV) wiggles. This due to the fact
of bad syncronysation between the analog video-signal and the digital-OSD
data.

My question how do i stop/synchronise my oscillator with software (and some
small hardware hacks) in a cheap and simple way. I'd like small sollutions.
Please reply your answer could be the key to a steadier tracking/OSD.
