Hello,
Looking at your code, first off I always put an infinite loop at the end of the
program. There isn't an "end" command. Instead the program counter
continues to run until it overflows back to 0. Then your program runs again.
I usually add a while(1); statement at the end of main() to send it off into a
nice coma.
Also, the software simulator is your friend. I sure do use it a lot. Try
removing the delay statements and step through the code while using the watch
window to look at PORTB. I've forgotten little things, like a CCP
peripheral forcing some ports to be inputs, etc... that drove me mad before I
found the answer.
