I'm using a Teensy 3.1 in Arduino mode.
In core_pins.h for Teensy 3 there are these defs:
which are the possible arg values for analogReference().
But DEFAULT and EXTERNAL are both zero... how does one tell the Teensy 3.1 to use AREF?
In core_pins.h for Teensy 3 there are these defs:
Code:
#define DEFAULT 0
#define INTERNAL 2
#define INTERNAL1V2 2
#define INTERNAL1V1 2
#define EXTERNAL 0
But DEFAULT and EXTERNAL are both zero... how does one tell the Teensy 3.1 to use AREF?
