Hi everyone

I'm using Keil uVision2, C compliler. I have a program with delays in it, but when I run it on the software and hardware platfrom the delays doen not seem to work. Am I calling the delays wrong or what? Can someone help me. Here is a sample code of my delay and how I call it. I call my delays in the main program as well as in my interrupt. A 12MHz X-tal is used. This is a 2 second delay.

delay( ) reentrant
{
unsigned int x;
for (x=0;x<50000;x++);
}

extenal( ) interrupt 0

do something;
do something;
delay( );
do something etc;


main( )

do something;
do something;
delay( );
do something etc;

Please help!
