Dot Graphic VFD Module
GU180x32D-K610A4
MACROS
A string of data and commands can be sent to the module and stored in non-volatile EEPROM by using the macro feature. This string of data and
commands can then be executed by using just one command. Up to 8 macros can be used at any one time, one of these is executed at power-up.
This example uses the first macro (Macro 0) to display an initial message at power-up.
WRITE TO MACRO-0 LENGTH
POWER-UP MESSAGE
1BH 00H 24H 10H 39H 0DH ‘PLEASE WAIT’
10H 21H 19H ‘INITIALISING SYSTEM’
Power-Up message using Macro 0.
This next example saves the previous graphic icon into Macro 1, and then is used as a user-defined character.

Using Macros as user-defined characters.
This example creates a display template, which can be helpful if many screens require the same look.

Using Macros as a screen template.
EEPROM PROTECTION
The EEPROM contains information such as macro data, asynchronous communication settings and I/O configuration. So it is important to protect
this information from stray commands due to communication failures. To protect the EEPROM, the module contains a ‘EEPROM Lock’ command
(1BH + 4CH). Once this command is issued, no further EEPROM updates can be made until it is unlocked (1BH + 55H). This feature is also
accessible from the set up menu, using the push button switch on the rear of the module.
USING THE CHECKSUM
All data written to the module is added to an internal checksum. The lower 8-bits of this checksum can be read at any time from the module by the
host system to confirm accurate data transfer. It is up to the user if or when this feature should be used. The checksum is cleared at power-up and
after each checksum read.
Example: Read checksum at power-up, or directly after it has been cleared.
READ CHECKSUM
1BH 43H
SENT TO HOST
Example: Read checksum after data has been written to the display.
