HI,

This code was finished few weeks ago, but because I need to read a lot materials about ARM and IAR and I need wait my wiggler work, so that I release it now.

// Include Standard files 

#include “Board.h”

void wait (unsigned int time )

 {

//* Begin     

 unsigned int waiting_time;    

 for(waiting_time = 0; waiting_time < time; waiting_time++) ; 

}//* End  

const int led_mask[8]= {LED1, LED2, LED3};  

int main() {

AT91F_PMC_EnablePeriphClock ( AT91C_BASE_PMC, 1 << AT91C_ID_PIOA ) ;     

 // then, we configure the PIO Lines corresponding to LED1 to LED4 

    // to be outputs. No need to set these pins to be driven by the PIO because it is GPIO pins only.

        AT91F_PIO_CfgOutput( AT91C_BASE_PIOA, LED_MASK ) ;

      // Clear the LED’s. On the EB55 we must apply a “1″ to turn off LEDs

         AT91F_PIO_SetOutput( AT91C_BASE_PIOA, LED_MASK ) ; 

            for (;;) 

    {       AT91F_PIO_SetOutput( AT91C_BASE_PIOA, LED_MASK );

wait(5000000);

AT91F_PIO_ClearOutput( AT91C_BASE_PIOA, LED_MASK) ;

wait(5000000); 

    }

// End for    

 }
