MPLABX and different board configurations

[JJalling]

Hi,

I have a product with a PIC microcontroller on the board. The board exists in (currently) two revisions, and each revision has a slightly different PIC micro (both PIC18).
Is it possible to support both boards in the same project in MPLABX?

How do you handle a situation like that? Have a project for each board revision, and keep the sources in sync betweeb the two?

You can add different configurations for one project. Each configuration has its own project settings (target processor, compiler, ... everything). Copy your "default" configuration as a starting point.

If your code depends on the board revision, you can add compiler macros (defines) for each configuration.

Code: [Select]

#if defined(BOARD_REV1)
    // conditional code
#elif defined(BOARD_REV2)
    // conditional code
#else
    #warning no board revision selected
#endif

Excellent, that does the job!! Thanks

Another option I've used in order to simplify field distribution of firmware is to probe the board at runtime during boot up. That way there's only one firmware file, but it assumes your using roughly the same processor, and the board versions aren't too dissimilar.
