I tried PIC18F46K20 C18 Lessons
1 lesson was successful- Build succeeded.
But I still have a problem- LED is not light on. Why?

I did all, what was in C18 lessons instruction, programmed corectly, but I
dont see the light. (I tried to load the demo of Pong, it was working).



The second problem is with blinking LED.

Here is the code: (default)
