- 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.
