I compiled my program and saw:
Multiple libraries were found for "Adafruit_MCP23017.h"
Not used: C:\Program Files (x86)\Arduino\libraries\Adafruit-MCP23017
But when I go to C:\Program Files (x86)\Arduino\libraries there is no Adafruit-MCP23017.
What is going on here and how do I stop the compiler from trying to access a file that doesn't seem to exist?
The program does run fine.
For the discussion of Arduino related topics.
