The compiler is choking on the the #include <PinChangeInt.h>? which is a separate include statement than the #include?PinChangeInterrupt.h
So my question is...is there a problem in the code (a mistype?) of one of the include statements or is there a separate library PinChangeInt.h that I am missing?
The first 4 lines of V1.27.1 are:
#include <PinChangeInt.h>
#include <EEPROM.h>
#include <Wire.h>
#include <PinChangeInt.h>
Which appear redundant as they are also included after the #define statements.
Maybe I should just comment these out and try again?
