4Mhz Circuit with a 20Mhz PIC

... a long shot but try blinking RB0 instead of RC2 (and report back).

I have moved my LED to RB0 and change my code, but not one of them are working now.
Am I missing something?

<code>
  Include "Modedefs.bas"

  DEFINE OSC 4 ' Set the Xtal frequency to 4mHz

  LEDPin VaR PORTB.0
  i var byte
Main:
 for i = 1 to 10
  High LEDPin
  Pause 400
  Low LEDPin
  Pause 400
 next i
end
</code>

Have you tried Oscillator setting on "HS"?

**koossa** · - 17th October 2007, 16:52

No
I will try

I have set it to HS, but still nothing.

Attach the compiled .HEX file that you are programming into the PIC here. If there's a
problem with your config settings, that makes it easy for someone to spot.
