star297 0:94bf5ec759da 5 This display requires 5v, 200mA power supply, serial and reset connections are 3.3v - 5v.
star297 0:94bf5ec759da 6 Set Oled to any serial port. It is Target dependant, some platforms may not work at
star297 0:94bf5ec759da 7 higher baud rates. Set baud rates as per the list in .cpp file, NOT in the program.
star297 0:94bf5ec759da 8 Freescale KLxx MCU's will only work upt to 128k baud and some have been defined.
