As I understand, Arduino IDE considers two paths for the libraries:
and second, the "libraries" folder next to the schetchbook.
I have a configuration.h file, that I include in the main file,
Test.ino, like this:
and in the
configuration.h file I try to include
SPI.h like this:
But I get the following error:
fatal error: SPI.h: No such file or directory
It seems that I am obliged to include
SPI.h only from the ino file. But why?
And how can I do what I want here? do I have to change IDE?
P.S: the software is large and I am improving maintainability.
