So you are able to manipulate the LED using the program you posted in your original post? I would like to try it with mine.
...Based on this assumption:- then a lot of people end up connected the LED the wrong way around and hence it NEVER lights.

If that is true, then I need to find a simple program that I can load to my MCU to make the light come on.
The reason for doing it this way around is the processors are much better at sinking current (ie being the place where the current flows into) than they are at sourcing current (ie being the place where the current flows from).
