MorganS:
For a single integer or even a float, why bother? It has to be transferred to SRAM to be used, so doing this forces the compiler to reserve some SRAM too.If you just use the const keyword, then the compiler can make up its own mind where to store it most efficiently. In 59% of cases, this will be more efficient than your idea of storage and the other 41% will come out the same as your enforced storage plan. Hint: since constants aren't variable, they aren't stored in SRAM at all.
Oh OK.
What is the point of the stuff in pgmspace.h about and why is the #include <avr/pgmspace.h> in Arduino.h ignored by the compiler?
I assume it is being ignored from some reason due the the compile error I am getting in my ino file.
Just curious - I will use your const suggestion.
