6. FUNCTIONS
6.1 Software Commands and Control Codes Description
6.1.1 Data Write (10H~FFH, RS=1)
6.1.2 Display Clear (01H, RS=0)
6.1.3 Display Position Home (02H, RS=0)
6.1.4 Entry Mode (04H/06H, RS=0)
6.1.5 Display ON/OFF Control (0CH/08H, RS=0)
6.1.6 Display Shift Left (18H, RS=0)
6.1.7 Display Shift Right (1CH, RS=0)
Write data to the display. In normal (LCD compatible) mode of operation, data is written to the display data (DD
RAM). When using the graphical data commands (F5H), 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.
Fills all locations in the display data (DD) RAM with 00h.
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 (I/D) is used to select the direction of the address counter on each data read or write.
If set to ‘1’, the address counter is increased (06H).
If set to ‘0’, the address counter is decreased (04H).
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.
Bit 2 (I/D) 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.
Shift the display left, one character position.
Shift the display right, one character position.
