The different Raspberry types, like Pi1, 3, 4, Zero (0) and 5, can be handled transparently to the control programs. This is done by a make variable TARGET identifying a concrete target machine, like e.g. meterPi or growPi. This will include the target machine's make include file makeTarg_<TARGET>_settings.mk, like e.g. makeTarg_meterPi_settings.mk.
This respective file will among other values set the PLATFORM variable by PLATFORM = raspberry_03 in the example.

The mechanism used is calculated make includes and calculated C includes (organised by this file config.h).
