PicKit3 Beginner Problem

[paulhaggard]

I just got my pickit 3 the other day, with the 18f45k20 demo board. I am attempting to go through the lesson files, and I did manage to get the compiler and linking files all sorted out. I got the first lesson working and was able to modify which LEDs turn on. So I tried to move on to the blinking LED/rotating LED lessons, and neither works. I compile them fine, program with no errors, but no LEDs are lit. I went back and tried lesson 1 again and it still works fine. How can I go about figuring out why the programming appears valid but does not operate the lights?

Thanks!

Solved

I figured it out; the brown out voltage was set too high in the code and the PIC was not running the program because of this. In the code under configuration bits, the value of 'BORV = 30' must be reduced to allow the code to run. 22 seems to work, but lower values give me build problems. What's weird is that I didn't need to reduce it to get the PWM lesson to run...
