    Multiple definitions of a function

    mahmoud.athab

       I have created a function named "keypad". then I have placed the function in a header file called "keypad.h".

         

      then I have used the keypad function all over the different ISRs. when I build the project I get this error:

         

      Build error: multiple definition of `keypad'

         

      I am quite sure that it is only defined once. so what is the problem?
