Something wrong with my keil?

But i think that it will not working yet. Can you send another screen shot from linker tab?

you need a delay function to see the blinking

  IOSET1   = 0x00010000;     // Set GPIO1.16 Output Pin (OFF LED)

  // Loop Blink LED on GPIO1.16 //
  delay_function();

    IOCLR1 = 0x00010000;

I corrected the while(1); issue because I had modified the original code and I forgot the infinite loop at the end. I still have nothing working.

Now I am just putting the Port Low but it is remaining @ 2.1V. How come. This is the code:

#include <LPC21xx.H>                                              // LPC2119 MPU Register


int main(void)
{
  PINSEL2 &= 0xFFFFFFFC;                                                                    // Makesure GPIO1.16 = GPIO Function
  IODIR1   = 0x00010000;                                                        // Set GPIO1.16 = Output
  IOSET1   = 0x00010000;                                        // Set GPIO1.16 Output Pin (OFF LED)

  // Loop Blink LED on GPIO1.16 //

    IOCLR1 = 0x00010000;                                                                        // Clear Output Pin P1.16 (ON LED)
        while(1);
}

This is a screen shot of the options. Is there anything wrong for LPC2119?

goto is an old technique for branching, long since lost in the sands of time.

It's good to know that C/C++ has no suitable looping construct for creating infinite loops, so a goto construct is needed.

did I forget to put a loop at the end of main to stop it ending?

can you compile it yourself?

int main(void)
{
  // la de da coding stuff

the_next_step:
  goto the_next_step;
}

I tried with this..

#include <LPC21xx.H>                                              // LPC2119 MPU Register

/* pototype  section */


int main(void)
{
  PINSEL2 &= 0xFFFFFFFC;                                                                    // Makesure GPIO1.16 = GPIO Function
  IODIR1   = 0x00010000;                                                        // Set GPIO1.16 = Output
  IOSET1   = 0x00010000;                                        // Set GPIO1.16 Output Pin (OFF LED)
        IOCLR1 = 0x00010000;                                                                    // Clear Output Pin P1.16 (ON LED)

}

But the same thing. Port 1 remained high.
Can you compile it and post the HEX contents so I can compare?

thanks a lot

I can make a smaller simple program first?

Obviously I cannot check if the delay is working because nothing is working on the stamp board.

Can I post the screenshots somewhere?

Have I checked the compiler switches? I need to check them. Will the delay function work? Will it always work? What can effect it? Is anybody listening?

Can you compile this code for an LPC2119 ?

I will compare it with what I get from the project that works.

I will post the results.

Can you be more specific? Do I have to specify where I write the code?
I dont remember doing this previously..
