Predefined Globals and Constants

To facilitate PIC programming, the mikroC PRO for PIC implements a number of predefined globals and constants.

All PIC SFR registers and their bits are implicitly declared as global variables. These identifiers have an external linkage, and are visible in the entire project. When creating a project, the mikroC PRO for PIC will include an appropriate (*.c) file from defs folder, containing declarations of available SFR registers and constants.

For a complete set of predefined globals and constants, look for “Defs” in the mikroC PRO for PIC installation folder, or probe the Code Assistant for specific letters (Ctrl+Space in the Code Editor).

Predefined project level defines

mikroC PRO for PIC provides several predefined project level defines that you can use in your project :

First one is equal to the name of selected device for the project i.e. if 16F887 is selected device, then 16F887 token will be defined as 1, so it can be used for conditional compilation :

    #ifdef P16F887
    ...
    #endif

The second one is value of frequency (in kHz) for which the project is built :

    #ifdef __FOSC__ == 80000
    ...
    #endif

Third one is for identifying mikroC PRO for PIC compiler:

    #ifdef __mikroc_pro_FOR_PIC__
    ...
    #endif

Fourth one is for identifying the build version. For instance, if a desired build version is 142, user should put this in his code :

    #if __mikroc_pro_FOR_PIC_BUILD__ == 142 
    ...
    #endif
