This module features a command set that is LCD compatible, allowing easy replacement in existing equipment with little or no modifications.
Careful consideration should be taken regarding the command execution times of this module. Although the commands can be executed within
40us, which is normal for LCD, busy times are increased when using the scroll write modes and with the cursor enabled. When using the 4-bit
parallel mode, a 40us delay is required between nibbles. Also reading back data in 4-bit parallel mode is not supported. DD RAM address
locations 70H+ are used to access the extended graphic commands.
At power up and reset the module is automatically initialised and ready to receive data. The interface is set to 8-bit, the display is cleared, the
cursor position is set to the top-left corner (DD RAM address = 00H), and the display luminance is set to 100%.
At power ON the modules internal reset requires at least 8mS before commands can be sent. Please check the busy status. If you connect pin 3 to
the hardware reset using jumper 3, the module will require 3mS to re-ilitialize. Reset is achieved by high-low-high transition of at least 100nS.
The module contains 3 font sizes, a proportional mini-font, 5x7 pixel, and a 10x14 pixel
font. Graphical text can be written to any part of the display using the ‘Set Graphic Cursor’
command (F0H). Characters are positioned above the current cursor position. Each
character written will include either a one pixel or two pixel space to the right side of the
character. After each character is written to the display, the cursor position is automatically
advanced. If the cursor position reaches the end of the display, the host must reposition to
the next line.
The following example displays two text messages in the center of the display using the
standard 5x7 character font. Command bytes that are underlined should be sent with RS
line low.
The next example displays one line of text using the 10x14 character font. Command bytes
that are underlined should be sent with RS line low.

In addition to the standard LCD commands, this module includes additional commands to display graphical data, different font sizes, fill, clear
and invert defined areas of the display. Also an outline command is available to draw rectangles around objects. When any of these extended
commands are executed, the module will change to the ‘graphics’ mode of operation. This graphics mode allows text to be written to any part of
the display.
There are many differences the user should be aware of when the display is in this graphics mode: -
The graphics mode is disabled as soon as any valid LCD command is received.

Written data may require additional busy times.
Text data is not written into the DD RAM and therefore can not be read back.
Graphical text can not be shifted onto the display.
The cursor is disabled & cursor direction is set to increment only.
UDF characters cannot be written.
