static key word in user functions

faqian huang

Can I use static key word in user function?

FUNC char StateMachine(void)
{
  static unsigned char _state;

  switch(_state)
  {
    case 0:
      ...
  }
}

    So the keyword static is supported implicitly in variable definition. Moreover the user guide does not state it is not supported explicitly.

    Not very convincing. Since your attempt to use it failed, it is certainly possible that the keyword is not supported.

    As your quoted text states "The basic capabilities and restrictions are:". Note the word 'basic' there. A full list of differences could end up being quite a substantial tome.

    Agreed - it certainly doesn't look like an exhaustive list.

    There is, apparently, no full formal published language specification/definition.

    So I would also conclude that 'static' is just not supported.

    If you want a definitive answer, you are going to have to contact Keil direct.

    Again, the forum is not the place to contact Keil support
