hello guys,
I am trying to make the timer0 interrupt to tick at 44.1KHz (LPC1769 XPresso board).

I made the above program and debug it to an oscilloscope (pin0.22-led),
but i get 25KHz.
What setting i am doing wrong ?:confused:

Any ideas?

All files attached below
Thanks

You're kidding :confused:

Your timer is running with 25MHz, your

#define TIMER0_INTERVAL 1000 //Timer0 reload compare value (Scope read 25KHz)

is dividing this by 1000, so what do you expect?
