/*
    This display requires 5v, 200mA power supply, serial and reset connections are 3.3v - 5v.
    Set Oled to any serial port. It is Target dependant, some platforms may not work at
    higher baud rates. Set baud rates as per the list in .cpp file, NOT in the program.
    Freescale KLxx MCU's will only work upt to 128k baud and some have been defined.
