Hi

I am newbie to work with LPC 1313 Microcontroller.Already I had Worked in 8 bit controllers.
i have written a code to toggle a led.That code was compiled without any errors and hex file also generated.


But thats not working in my board.So i suspect on hex file generation and in my coding..i will post my code.
Is there any procedure for generating hex file.?

Thanks in advance


Code:
#include "LPC13xx.h"
#include <cr_section_macros.h>

/*----------------------------------------------------*/

int main(void) {

	LPC_SYSCON->SYSAHBCLKCTRL |= (1 << 6);	/* Enable clock to the GPIO peripheral */

	LPC_GPIO1->DIR |= (1 << 5);				/* Set pin direction of PIO1_5 as output */


	int i;

    while(1) {								/* Until power is available */

    	LPC_GPIO1->DATA |= (1 << 5);		/* Set the output of PIO1_5 as one */

    	for(i = 0; i < 1000000; i++) {		/* Wait (500ms approx.) */
    	}

    	LPC_GPIO1->DATA &= ~(1 << 5);		/* Set the output of PIO1_5 as zero */

    	for(i = 0; i < 1000000; i++) {		/* Wait (500ms approx.) */
    	}

    }
    return 0 ;
}
/*----------------------------------------------------*/

To test it will be better if you zip and post the complete LPC Xpresso project files.

Is this a development board with the LED already incorporated in the design?

If so, do you have a schematic of the board? Or link where it can be downloaded?

If not, what are the specs of the LED and how is it specifically attached to the port pin?

Also, what is the frequency of the external crystal or oscillator?

yeah..this is a development board which was designed by us.i will upload the snap of the board.It is attached to the Port pin through 2.7k.we are not using any external oscillator.

Typically the LPC1313 can only sink or source 2-3mA per pin and if an internal pullup is active, the VOH drops to about 2.7V.

What are the current requirements and VF of those LEDs?
