Standard Timer interrupt in LPC3250

Ravi Teja Paleti

Hi

I am Unable to generate a interrupt for standard timers in LPC3250 . Are there any changes to make to lpc3250.s and configuration settings in the same lpc3250.s . I am using the keil compiler.
I am initialising the Timer clock in TIMCLK_CTRL1 and then
T0TCR=0x01;
T0CTCR=0x00;
TOMCR=0x03;

At this point of debuggig it is running continously without entering into Interrupt Service Routine.

I tried many different settings shown in web but invain

    So ... You have written code and it runs as long as you don't use timer interrupts.

    What part of the IDE do you think would cause a problem like this?

    If the compiler can produce code for the processor (which it can) and you can download code which executes correctly (which I think you've said you can) then, fundamentally, things are working.

    It is far more likely to be a problem with how you are configuring the timer and the interrupt controller.
