Hi,

I am using TMS570LS3137 MCU  to capture frequency and display the value in hyperterminal, i need to make a NHET1 pin has interrupt pin but little bit confusing in Halcogen 3.02 , can tell me the procedure to get following features.

1.NHET1[0 to 19] pins need to make acitve low interrupt pin.

2. which is the ISR function in het.c

Regards,

Chethan kumar

    Chethan,

    Your question does not seem to be TI-RTOS related, so I have moved this thread over to the device forum in hopes that you will get a faster response there.

    Chethan,

    I actually don't have HalCoGen 3.02 loaded,  current version is 4.02.

    It's free so please upgrade if possible.

    In 4.02 there is an Edge Interrupt tab in which you can enable the interrupts from the edge detect pins,

    and an 'Edge 0-7' tab where you can select which edge and which pin.

    Generally speaking there are more options available to you if you were to write your own HET program.
    If you really need a level interrupt and cannot substitute a falling edge interrupt, then we can discuss getting you started w. HET IDE.
