Here is my code, and nothing at all happen
With the PIC16F877-20l/P it is working, but when I switch it with the PIC16F877-20/P it does not work.


<code>
&nbsp;&nbsp;Include "Modedefs.bas"

&nbsp;&nbsp;DEFINE OSC 4 ' Set the Xtal frequency to 4mHz

&nbsp;&nbsp;LEDPin VaR PORTC.2
&nbsp;&nbsp;i var byte

Main:
&nbsp;&nbsp;for i = 1 to 10
&nbsp;&nbsp;&nbsp;&nbsp;High LEDPin
&nbsp;&nbsp;&nbsp;&nbsp;Pause 400
&nbsp;&nbsp;&nbsp;&nbsp;Low LEDPin
&nbsp;&nbsp;&nbsp;&nbsp;Pause 400
&nbsp;&nbsp;next i
end
