Predefined Globals and Constants

To facilitate dsPIC30/33 and PIC24 programming, the mikroC PRO for dsPIC30/33 and PIC24 implements a number of predefined globals and constants.

All dsPIC30/33 and PIC24 SFR registers are implicitly declared as global variables of volatile unsigned int. These identifiers have an external linkage, and are visible in the entire project. When creating a project, the mikroC PRO for dsPIC30/33 and PIC24 will include an appropriate (*.c) file from defs folder, containing declarations of available SFR registers and constants (such as PORTB, ADPCFG, etc). All identifiers are in upper case, identical to nomenclature in the Microchip datasheets. All dsPIC30/33 and PIC24 SFR registers are also available as structures with bitfields named identically to the Microchip datasheets in order to facilitate bit access e.g

TRISBbits.TRISB3 = 1.

For a complete set of predefined globals and constants, look for “Defs” in the mikroC PRO for dsPIC30/33 and PIC24 installation folder, or probe the Code Assistant for specific letters (Ctrl+Space in the Code Editor).

Predefined project level defines

mikroC PRO for dsPIC30/33 and PIC24 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 P30f4013 is selected device, then P30f4013 token will be defined as 1, so it can be used for conditional compilation :

    #ifdef P30F4013
    ...
    #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 dsPIC30/33 and PIC24 compiler :

    #ifdef __mikroc_PRO_FOR_DSPIC__
    ...
    #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_DSPIC_BUILD__ == 142 
    ...
    #endif
