Graphic Display Module
6.2 Jumper Setting
6.3 Display Examples
6.3.1 Serial Control (Select Font Mode “6
6.3.2 Extended Graphic Commands
The selection switches are located on the PCB right side. The switch settings are read only when the power is turned on.
Therefore, changing the settings while the power is on has no effect.
An additional command has been included to distinguish between command and data writes. When using serial
communications. This command (0FH) will temporarily set RS line low for the subsequent written byte. The following
example displays two text messages using the serial communications and the ‘Set RS Low’ command:
In addition to the standard LCD commands, this module includes additional commands to display graphical data and
different font sizes. 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.
