Data Byte 8
A "1" bit indicates an on (black) pixel, a "0" bit indicates an off (clear) pixel.
Once defined, a character is displayed simply by issuing a value (0x00 to 0x07) corresponding to the
character number. The character will be laid out as follows;

NOTE Custom characters will be erased if any of the "Initialize bar graph" commands
are issued.
Example of a degree symbol;
txUart.sendByte(0xFE); //command prefix
txUart.sendByte(’N’); //custom character command
txUart.sendByte(0x00); //custom character value 0-7
txUart.sendByte(12); //8 bytes to create
txUart.sendByte(18); //the custom character
txUart.sendByte(18);
txUart.sendByte(12);
txUart.sendByte(0);
txUart.sendByte(0);
txUart.sendByte(0);
