5.1 Introduction
begin displaying data. This means that it is able to display all characters and strings that are sent to it, which
are defined in the current character set. The display module will begin displaying text at the top left corner
of the display area, known as home, and continue to print to the display as if it was a page on a typewriter.
When the text reaches the bottom right row, it is able to automatically scroll all of the lines up and continue
to display text, with the auto scroll option set to on.

NOTES
speed
LSB = 0x93 (rounded)
MSB = 0x00
Intended Baud Rate: 13,500 baud
Results from the formula are rounded down to the nearest whole number (i.e 73.07
= 73).
This formula becomes less acurate as baud rates increase, due to rounding.
Place the speed result backwards into the formula to receive the actual baud rate.
(Baud
The actual baud rate must be within 3% of the intended baud rate for the device to
communicate.
This command is not available in I2C mode.
