If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

Out of interest Dave, did you try inverting the MCLRE config assignment ?Originally Posted by g7jiq
The only reason I suggested it may be a problem was because I had a similar problem once. Now that you mention whcih programmer you used I recall that was the same programmer I had when I had the problem. (Did you know you can upgrade the firmware of that thing to the latest version to make it cover more pics with more memory etc ? it's worth looking into.)
As for the led and the opto in series, you had a 470ohm resistor across 0.4V, which means the current limiting was in the order of I=V/R = 0.4/470 = 0.00085 A (850uA microamps)
That's not normally enough to drive anything requiring a strong switching signal, though most TTL circuits should cope.
