Making libraries work for Photon AND Core?

You can look here

Preprocessor #ifdef to Detect Platform Type (Core/Photon) at Compile Time

So this may be a soon to be irrelevant question, once 0.4.x goes live for the Core, but it appears that right now, 0.3.4 has a define SPARK in the makefile (this issue), but doesn’t define PLATFORM_ID. However, 0.4.x defines PLATFORM_ID (for use in differentiating Core from Photon from Electron, etc.) but has removed the definition of SPARK in the makefile, so a #ifdef SPARK statement will no longer work. This is somewhat annoying, and is there a better way to deal with it other than this? #if…

But if you use digitalReadFast() pinReadFast(), digitalWriteFast(), pinSetFast() and pinResetFast() instead of the hardware specific alternatives you may even get away without these.
