Dot Graphic VFD Module
GU180x32D-K610A4
DISPLAYING TEXT
The module contains 3 font sizes, a proportional mini-font, 5x7 pixel, and a 10x14 pixel font.
Characters of any size can be written to any part of the display. All data sent to the module from
20H to FFH is treated as character data. Characters are positioned above the current cursor
position, see Fig1. Each character written will include a one pixel space on 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.

The module can display a cursor to aid character positioning and text input. The
size of the cursor depends upon the currently selected font, and can be set to flash
or remain static.

DISPLAYING GRAPHICS
Using the cursor to aid user input.
Graphical images can be displayed on the VFD module in either a horizontal or vertical byte orientation. After each graphical data write, the cursor
is automatically advanced, depending upon the direction selected in the ‘Write Mode’ command. The most significant bit is positioned to the top
(vertical data) or to the left (horizontal data).
The following example displays a simple graphical image using horizontal graphic data. The write mode
is first set to horizontal data format, with a vertical cursor movement. The cursor is positioned before
sending the 8 byte of graphical data using the graphics command.

The next example displays a simple graphical image using vertical graphical data. The write mode is
first set to vertical data format, with a horizontal cursor movement. The cursor is positioned, then the
top 20 bytes are sent using the graphic write command. The cursor is then repositioned to send the
bottom 20 graphical bytes.
