Note: After these commands are executed, the cursor will be disabled and any character data will be written to the display only, and not the DD RAM. Any subsequent LCD compatible command will
re-enable the cursor and allow for DD RAM writing.
NORITAKE ITRON VFD MODULES
Description
Write user defined character 1-8 to the current cursor location on the display.
Write data to the display. In normal (LCD compatible) mode of operation, data is written to the display data
(DD RAM) or character generator (CG RAM).
When using the graphical data commands (F0H, F1H & F2H), data is written direct to the display and is not
stored in DD RAM. Data write busy times will increase when using the graphic functions.
Read data from the display. In normal (LCD compatible) mode of operation, data is read from the display
data (DD RAM) or character generator (CG RAM).
Description
D0 – D6 of read data corresponds to the current cursor position. D7 shows the status of busy.
Fills all locations in the display data (DD) RAM with 20H (blank character). The address counter is set to 0 in
the DD RAM. The address counter is set to increment on each data read/write. Any display offset (using the
display shift command) is removed.
The address counter is set to 0 in the DD RAM. Any display offset (using the display shift command) is
removed.
Bit 1 is used to select the direction of the address counter on each data read or write. If set to ‘1’, the address
counter is incremented. If set to ‘0’, the address counter is decremented.
Bit 0 enables the display to shift on each data read/write. If this bit is set to ‘1’, the display is shifted with the
cursor. The display shift direction depends upon the address counter direction (bit1). If this is set to
increment, the display is shifted left, if the address counter is set to decrement, the display is shifted right.
Note: When display shift is enabled, the data write busy time can increase by 200us.
Bit 2 is used to enable or disable the display. If this bit is set to ‘0’ the VFD’s power supply is turned off to
reduce power consumption.
Bit 0 enables the flashing block cursor.
Note: If the cursor is enabled, busy times can increase by 20us.
Shift the cursor position (address counter) one position to the left.
Shift the cursor position (address counter) one position to the right.
Shift the display left, one character position.
Shift the display right, one character position.
Enables 4-bit communications. Data is received on DB4-DB7 only. Two writes are required to send one data
byte. The most significant nibble should be sent first. Refer to the ‘Parallel Communications’ section for more
information. The lum value sets the displays brightness, and must be sent with the RS line high: -
00H = full brightness, 01H = 75%, 02H = 50% & 03H = 25%.
Enables 8-bit communications. Data is received on DB0-DB7. The lum value sets the displays brightness,
and must be sent with the RS line high: - 00H = full brightness, 01H = 75%, 02H = 50% & 03H = 25%.
Set the character generator address (CG RAM). All written data is placed within the user definable character
area.
Set the display data address (DD RAM). 80H – 93H = top line. C0H - D3H = bottom line.
Set the absolute cursor position. xpos = 0 – 139, ypos = 0 – 15.
Co-ordinates should be written with RS line set high.
Area Commands: - ‘I’ - invert area, ‘F’ – fill area, ‘C’ = clear area, ‘O’ – set outline, ‘o’ – clear outline.
All area commands should be preceded with the area co-ordinates. X1 Y1 left top X2 Y2 bottom right.
Co-ordinates, command and graphical data should be written with RS line set high.
Image Commands: - ‘H’ – write horizontal graphical data with horizontal cursor movement.
‘V’ – write vertical graphical data with horizontal cursor movement.
‘h’ – write horizontal graphical data with vertical cursor movement.
‘v’ – write vertical graphical data with vertical cursor movement.
Graphical data should immediately follow the ‘H’,’h’,’V’ and ‘v’ commands.
Co-ordinates, command and graphical data should be written with RS line set high.
Select font type, font size and font spacing.
Font commands: - ‘A’ or ‘a’ = proportional 64 character mini-font.
‘B’ = 5x7 LCD compatible font with Katakana characters.
‘C’ = 10x14 LCD compatible font with Katakana characters.
‘b’ = 5x7 international font with European characters.
‘c’ = 10x14 international font with European characters.
‘1’ = set the inter-character pixel spacing to 1 pixel.
‘2’ = set the inter-character pixel spacing to 2 pixels.
Font command should be written with RS line set high.
Bit 7 High = I/O Port, Low = Serial Port. See extended port and serial commands.
The current port status is read with RS high. See extended port and serial commands.
byte is output from the port. In serial mode check the busy status before sending again.
The current port levels or buffered received data can be read with RS high.
Up to 128 bytes of data can be buffered before being transmitted from the serial port.
Additional Serial Data Commands
Set the RS line low for the following byte only. Used in serial communications only.
Read data at current cursor position. This command is used with serial communications only.
Read current cursor position. This command is used with serial communications only.
