    [​IMG]If you tell us which compiler you use it will be more simple:rolleyes:

    Or if you're using a compiler at all!

    But first, what have you discovered by reading the Microchip manual?

    If you are using assembler go to your "program files/microchip/MPASM suite/template/code" folder and you should find the basics. All you need to do then is enable the interrupt and handle it.

    And what kind of interrupt?

    Why is that that some people put zero effort into their questions when asking for help?

    That tells us precisely nothing.

    MPLAB is an IDE (integrated development environment) and can be used with many many different programming languages and compiler versions. Saying you use mplab is like saying you use a pencil and paper, it does not tell us what compiler you are writing your code for or even what programming language you are using.

    If you are writing in assembler take a look at http://www.gooligum.com.au/tut_midrange.html. Section 6 has a good tutorial on interrupts.

    If you are writing in a high level language then you will have to refer to your compiler documentation to find out how the compiler handles interrupts. Each compiler does it differently so do read the documentation.

    You did not answer one question of and the questions asked to you. People are spending their valuable time trying to help you yet you put no effort at all into helping them help you.

    Why should anyone continue to try to help if you refuse to help yourself?
