I have some program on ADSP-21489 who controll some device usin SPI.
I have macro file and C file for this device.
Now i want to use the same program but to replace the controlled device- i need to create another macro file and another C file ( according to changes in registers and in functionality).
How should i implement those 2 types of files and choose ,before compilation , the type i want?
further explanation for my issue - lets say that i want to use # ifdef for whole files - to generate generic program.
