Dear all,
I'm new to Arduino and I am trying to figure out how to identify if the code is running inside an Atmega328P-PU or AU which has 2 extra analog pins.
Anyone has an idea?
Thanks for your time
X
#if NUM_ANALOG_INPUTS == 8
// Running on a chip with 8 analog inputs
#endif
This works because of the:
name.build.variant=eightanaloginputs
in boards.txt which selects hardware/arduino/variants/eightanaloginputs/pins_arduino.h which contains:
#undef NUM_ANALOG_INPUTS
#define NUM_ANALOG_INPUTS 8
Amazing!! 
Perfect and thanks a lot!
I used it as follows:
//Identify which uController is running this code
boolean fullFeatures = NUM_ANALOG_INPUTS == 8;
Cheers
