delay_ms not as expected

Thanks for the reply ard_newbie, yes that code works as you intended it to be used. But do you know why if I just use your Delay routine in my code it doesn't work. i.e

while(1) {

REG_PIOB_SODR = PIO_PB27;

Delay(500);

REG_PIOB_CODR = PIO_PB27;

}

So whats so different from this apart from the xor:

while(1) {

REG_PIOB_SODR = PIO_PB27; //Enable output

Delay(500);

REG_PIOB_CODR = PIO_PB27; //Disable output
}

And the following actually works:

while(1) {

REG_PIOB_SODR = PIO_PB27;

for (i=0;i<1000;i++)
{
for (j=0;j<2000;j++) k = i-j;
}

REG_PIOB_CODR = PIO_PB27;

for (i=0;i<500;i++)
{
for (j=0;j<2000;j++) k = j-i;
}
}
