[swami.gangatharan]

I build the Led blinking code for LPC 2148. in Evaluation mode i can simulate the code . i can load the code in to the CPU but not working .please any one help me..
Thanks in Advance...

#include <LPC214X.H>

void delay(void);
int main(void)
{
   
    IO0DIR |= (1<<22);

	
    while(1)
    {
      
    
            IO0SET |= (1<<22);
 			      delay();
            IO0CLR |= (1<<22); // Turn them off
            delay();			// drive P0.30 High
       }
    
    return 0; // this wont execute ever :P
}
void delay(void)
{
    int z,c;
    c=0;
    for(z=0; z<40000; z++) // You can edit this as per your needs
    {
        c++; // something needs to be here else KEIL compiler will remove the for loop!
    }
}

Define P0.22 as GPIO port Use PINSEL fiunction..
