GLK12232-25 Datasheet, Funktion
Auto Repeat Mode Off
ASCII '`', Hex 60 Decimal 96
Syntax 0xFE 0x60
www.DataSheet4U.com
To turn auto repeat off, send a command prefix followed by the character '`'.
Auto Line Wrap On
ASCII 'C', Hex 43, Decimal 67
Syntax 0xFE 0x43
This command enables the automatic line wrap function. Transmitted characters which overrun the width of the display
will automatically wrap to the next line. The bottom line wraps to line 1 of the display. To carry out this command the user
must send a command prefix followed the character 'C'.
Auto Line Wrap Off
ASCII 'D', Hex 44, Decimal 68
Syntax 0xFE 0x44
This command disables the automatic line wrapping function. To turn off the auto line wrapping, send a command prefix
followed by the character 'D'.
Auto Scroll On
ASCII 'Q', Hex 51, Decimal 81
Syntax 0xFE 0x51
To enable auto scroll, send a command prefix followed by the character ‘Q’. When auto scrolling is on, it causes the GLK to
shift the entire display’s contents up to make room for a new line of text when the text reaches the scroll position defined by
the “Set Font Metrics” command in the GLK memory.
Auto Scroll Off
ASCII 'R', Hex 52, Decimal 82
Syntax 0xFE 0x52
When auto scrolling is disabled, text will wrap to the top left corner of the display area. Existing graphics or text in the
display area are not erased before text is placed; when using proportional fonts without auto scrolling, care should be taken
to clear areas where text is being written , particularly when wrapping occurs.
Clear Display
ASCII 'X', Hex 58, Decimal 88
Syntax 0xFE 0x58
To clear the screen of the GLK, send a command prefix followed by the character ‘X’. This command clears the display and
resets the text write position to the top left of the screen.
Set Contrast
ASCII 'P', Hex 50, Decimal 80
Syntax 0xFE 0x50 <contrast>
This command sets the display's contrast to <contrast>, where <contrast> is a value between 0x00 and 0xFF (between 0
and 255). Lower values cause "on" elements in the display area to appear lighter, while higher values cause "on" elements to
appear darker. Lighting conditions will affect the actual value used for optimal viewing. Individual GLK modules will also
differ slightly from each other in appearance. In addition, values for optimal viewing while the GLK backlight is on may
differ from values used when backlight is off.

Write to Bar Graph
ASCII 'i', Hex 69, Decimal 105
Syntax 0xFE 0x69 <reference number><value>
www.DataSheet4U.com
This command sets the bar graph <reference number> to value <value>
Set Current Position (Graphic)
ASCII 'y', Hex 79, Decimal 121
Syntax 0xFE 0x79 <x position><y position>
This command sets the next position for text placement via a individual pixel location. The coordinate (<x position>,<y
position>) defines a pixel on the screen where the top left corner of the screen is defined as (0,0). This pixel location will
be used as the top left corner of the next character of text which is sent to the module without any regard to "font metrics"
like character spacing or line spacing.
Display Saved Bitmap
ASCII 'b', Hex 62, Decimal 98
Syntax 0xFE 0x62 <reference number><x location><y location>
This command causes a previously stored bitmap referenced by <reference number> to be displayed to the screen at pixel
location (<x location>, <y location>) where this location defines the top left corner of the bitmap.
