SOFTWARE COMMANDS

UDF Write 00H – 0FH Write user defined character 1-8 to the current cursor location on the display. Data Write

(40us – LCD compatible mode) (250us – Graphic mode)

Data Read

(40us – LCD compatible mode)

00H – FFH 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.

00H – FFH 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).

Port Configure F4H + byte Bit 7 High = I/O Port, Low = Serial Port. See extended port and serial commands. Read Port Status F5H The current port status is read with RS high. See extended port and serial commands. Port Out / Serial Send F6H + byte byte is output from the port. In serial mode check the busy status before sending again. Port In / Serial Read F7H The current port levels or buffered received data can be read with RS high. Port Buffer Send F8H + size + data Up to 128 bytes of data can be buffered before being transmitted from the serial port.

00H - FFH D0 – D6 of read data corresponds to the current cursor position. D7 shows the status of busy.

01H 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.

02H The address counter is set to 0 in the DD RAM. Any display offset (using the display shift command) is

removed.

04H – 07H 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.

08H-0FH 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.

10H Shift the cursor position (address counter) one position to the left.

14H Shift the cursor position (address counter) one position to the right.

18H Shift the display left, one character position.

1CH Shift the display right, one character position.

20H + lum (RS=1) 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%.

30H + lum (RS=1) 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%.

40H – 7FH Set the character generator address (CG RAM). All written data is placed within the user definable character

area.

80H – E7H Set the display data address (DD RAM). 80H – 93H = top line. C0H - D3H = bottom line.

*Note

F0H + xpos + ypos Set the absolute cursor position. xpos = 0 – 139, ypos = 0 – 15.

Co-ordinates should be written with RS line set high.

F1H + x1 + y1 + x2 + y2 + cmd 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.

‘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.

F2H + font 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.

Instruction Data Format Additional Serial Data Commands

Set RS Low 0FH Set the RS line low for the following byte only. Used in serial communications only. Read Data FEH Read data at current cursor position. This command is used with serial communications only. Read Cursor Position FFH Read current cursor position. This command is used with serial communications only.

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.

This module has a fast latching 8-bit data bus. The ‘RS’ and ‘R/W’ control lines should be set prior to the rising edge of the ‘E’ enable line. Data is clocked in on the falling edge of the enable line. The busy line should be checked before sending data.

The data bus width can be selected for 4-bit operation, using data lines D4-D7. Within this mode, two writes are required to send one data byte. The high nibble (bits 4-7) should be sent first, followed by the low nibble (bits 0-3). The busy state is not triggered between nibbles. It is important that the status is NOT read within 40us of sending the command to set either 4 or 8 bit mode.
