Definitions Directory:

These files are templates for the various applications and controllers.  They
may be included "as is", otherwise copy the ones you need to your own source
directory then modify as appropriate.

Typically, the only modification that will be made will be to register your
application to receive messages.  For example:

Copy:
  definitions\def_brd_ms120.m
To:
  mysource\def_brd_ms120.m

Then change:
  IO_INPUT( IO6,       PORTA,   7,    NOPULLUP,   ACTIVEHIGH,    0 ) // Connector I/O  6 uses PA7
To:
  IO_INPUT( TankFull,  PORTA,   7,    NOPULLUP,   ACTIVEHIGH,    A(MyApp) ) // Connector I/O  6 uses PA7

Thus, "MyApp" will now receive notifications about changes to IO 6 that is now called "TankFull".
