|
|
|
||
Instruction / Busy time |
Data Format (RS = 1) |
Description |
|
|
||
UDF Write |
00H – 0FH |
|
Write user defined character 1-8 to the current cursor location on the display. |
|||
Data Write |
00H – FFH |
|
Write data to the display. In normal (LCD compatible) mode of operation, data is written to the display data |
|||
(40us – LCD compatible mode) |
|
|
(DD RAM) or character generator (CG RAM). |
|||
(250us – Graphic mode) |
|
|
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. |
||
Data Read |
00H – FFH |
|
Read data from the display. In normal (LCD compatible) mode of operation, data is read from the display |
|||
(40us – LCD compatible mode) |

|
data (DD RAM) or character generator (CG RAM) |
|||
Instruction / Busy time |
Data Format (RS = 0) |
Description |
|
|
||
Status / Cursor Position |
00H - FFH |
|
D0 – D6 of read corresponds to the current cursor position. D7 shows the status of busy. |

|
|
|
|
|
|
(40us – LCD compatible mode) |
|
|
|
|
|
|
Display Clear |
01H |
|
Fills all locations in the display data (DD) RAM with 20H (blank character). The address counter is set to 0 in |
|||
(150µs) |
|
|
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. |
||
Cursor Home |
02H |
|
The address counter is set to 0 in the DD RAM. Any display offset (using the display shift command) is |
|||
(500µs) |
|
|
removed. |
|
|
|
Entry Mode |
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 |
|||
(40µs) |
|
|
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 150us. |
||
Display Control |
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 |
|||
(50us) |
|
|
reduce power consumption. |
|||
|
|
|
|
Bit 0 enables the flashing block cursor. Note: If the cursor is enabled, busy times can increase by 20us. |
||
Cursor Shift Left |
10H |
|
Shift the cursor position (address counter) one position to the left. |
|||
(40us) |
|
|
|
|
|
|
Cursor Shift Right |
14H |
|
Shift the cursor position (address counter) one position to the right. |
|||
(40us) |
|
|
|
|
|
|
Display Shift Left |
18H |
|
Shift the display left, one character position. |
|||
(150us) |
|
|
|
|
|
|
Display Shift Right |

|
Shift the display right, one character position. |
|||
(150us) |
|
|
|
|
|

|
Enables 4-bit communications. Data is received on DB4-DB7 only. Two writes are required to send one data |
|||
(40µs) |
|
|
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%. |
||
Select 8 bit interface |
30H + lum (RS=1) |
|
Enables 8-bit communications. Data is received on DB0-DB7. The lum value sets the displays brightness, |
|||
(40µs) |
|
|
and must be sent with the RS line high: - 00H = full brightness, 01H = 75%, 02H = 50% & 03H = 25%. |
|||
Set CG Address |
40H – 7FH |
|
Set the character generator address (CG RAM). All written data is placed within the user definable character |
|||
(40us) |
|
|

|
|
|
Set DD Address |
80H – E7H |
|
Set the display data address (DD RAM). 80H - 8FH = top line. C0H - CFH = bottom line. |
|||

|
|
|
Set Graphic Cursor *Note |
F0H + xpos + ypos |
|
Set the absolute cursor position. xpos = 0 – 111, ypos = 0 – 15. |
|||
(40us) |
|
|
Co-ordinates should be written with RS line set high. |
|||
Set Area *Note |
F1H + x1 + y1 + x2 |

PARALLEL COMMUNICATIONS
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.

4-Bit Data/Command Write Timing Diagram.
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.
