I have tried three power supplies - Using one for circuit and one for LEDS, and also using the same supply split with a voltage regulator for the PIC circuit. The LED supply is a hefty (and expense!) 12v 8.5 amp supply that should be more than adequate to power 10meters of 5050 smd RGB leds;

36watts per 5 meters - From Manufacturer
Thus 10m = 72 watts
72 / 12v = 6 amp.
I believe that calculation is correct. No smoke yet anyway...

On your suggestion, I have set PCON.2=0 (BOR = OFF) and the problem persists.

Any other ideas? I read something about PCL tables...

Many Thanks!





The LED strips have their own resistors. As I am cycling through the colours - there are only ever two colours on at the same time (interesting spectral information!).
