In my RA02.h below, the preprocessor does not find MCU_TYPE defined in the original sketch. I have tried both #define MCU_TYPE 68 and #define MCU_TYPE DUE_R3
My goals here are two:
(1) Make hardware changes only in OriginalSketch.ino
(2) Instantiate those changes in various Hardware.h and Hardware.cpp files, but require no manual changes each time.
How I know I have a problem:
(1) My #if MCU_TYPE == MKR_WiFi_1010 guard below always evaluates #else
(2) The IDE editor does not identify MCU_TYPE in RA02.h as a macro when I hover over it.
It occurs to me that this may be a matter of the order in which the translation units are compiled. Other similar comparisons work, for example #if MCU_MODE == RX_MODE. At execution time though, MCU_TYPE reliably evaluates as 68. What path to follow?
