hello friends unable to run the interrupt so plz frirends cuns u send me some
sample codes to run the interrupt
#include
void RTC_isr(void)
{

if(ILR&0x01)
{

}

ILR = (1UL<<0); /* Clear RTC counter increment interrupt flag */
ILR = (1UL<<1); /* Clear RTC alarm interrupt flag */
VICVectAddr = 0; /* Acknowledge Interrupt */
}
/* Default Interrupt Function: may be called when ISR is disabled */
void DefISR (void) {
}
int main()
{
VPBDIV=0x02;

Interrupt */

I have tried your code in Uvision simulator with LPC2114 and the interrupt is called and executed so what is the problem?
Maybe a hardware problem with the RTC?

when the interupt is callled the port bits are not set
thats the problem and can u send some example for real time clock programs or a tutorial for real time clock
i need a program for to run the clock and generate an interrupt for every 20 minuntes

How about the use of ioclr1 to turn off the LEDs ?

I just noticed that the interrupt function declaration is missing the
__isr prefix, it should be
__isr void RTC_isr(void)
Also both if(ILR&0x01) and if(ILR&0x03) are true every time the
interrupt fires (because IRL equals 1) so you should consider using
if(ILR&0x02) to check the alarm flag

What do you mean by that?
Your original code wasn't giving any errors and adding __isr compiles fine too.
You still haven't specified your compiler , is it keil uvision or not?
When you ask your help you have to provide proper info, you didn't tell us your mcu model, the compiler or the error you get.
First it was the interrupt not executing and now you say more errors , what kind of errors?

This student want's us to program his school project,
look at the quote from his email at 16:12 :
sorry i did not get can u reprogram that my program with interrupt
genterating for every 20 min plz do this
I am not going to do that.
Preetham,
If you want help you should provide all the information necessary
to us to be able to help, like processor, compiler and most important
the stuff and information you have already tried and read.
Alex has asked you for that and it should have been the first pieces
of information in your original post.
