It seems that something has passed unnoticed: the MCLR pin is tied to GND so
the device will be kept in reset all the time. How does it work then?
As much as I can understand from the data sheet it should be logic high for
the device to function.

Or it's another "patent" idea? ;)

You should also be using a series resistor with the LED to limit the current
unless you just want to drain the batteries really quick. A good lecture on
this should be the Ohm's Law? The voltage drop on usual LED is approx. 1.8V.
The Pic pin will handle 25mA max and the LED needs 10-20mA for bright
results.

So this configuration may make you the surprise of  -GREAT! IT'S WORKING!
and after two minutes - WHY DID THE CAT DIED? CURIOSITY PERHAPS? (no, too
much current trough it's fur but didn't realize that until it started
smelling).

After all why do you need - The Stupendous - PIC 16f877 to make a flashing
LED?

Do you always need the BIG things to make the SMALL jobs?

Are you perhaps a woman?


Wait I have an idea! R=U/I shuld I go for a patent?
