LED Backlight
Standard display EA DIPS082-HN is reflective, non-backlighted version. Module with part number
EA DIPS082-HNLED comes with yellow/green LED backlight. Power consumption for backlight is 50mA
typ. and 80mA max. Backlight is permanent switched on. Supply voltage with backlight is 5V only.
For individual use LED backlight can be switched on and off after doing the following modification:
Remove series resistor R5 and change resistor from R6 to R7. Now a positive voltage at pin 7 (D0)
powers Anode of backlight direct. To limit LED-current an external series resistor is required (R
0,8V / I
). Please note that in this case display interface is 4-bit mode only !

Description
0
Clears all display and returns the cursor
to the home position (Address 0).
Returns the Cursor to the home
position (Address 0). Also returns the
display being shifted to the original
position. DD RAM contents remain
unchanged.
Sets the Cursor move direction and
specifies or not to shift the display.
These operation are performed during
data write and read.
Sets ON/OFF of all display (D) cursor
ON/OFF (C), and blink of cursor position
character (B).
Moves the Cursor and shifts the display
without changing DD RAM contents.
Sets interface data length (DL) number
of display lines (N) and character font
(F).
Sets the CG RAM address. CG RAM
data is sent and received after this
setting.
Sets the DD RAM address. DD RAM
data is sent and received after this
setting.
Reads Busy flag (BF) indicating internal
operation is being performed and reads
address counter contents.
Writes data into DD RAM or CG RAM
Reads data from DD RAM or CG RAM

Character set
Below shown character set is already built in. Additionally 8 self defined characters can be attached.
CREATING YOUR OWN CHARACTERS
All character display modules offered in this catalogue, are able to create 8 own characters (ASCII Codes 0..7) in
addition to the 192 ROM fixed codes.
1.) The command "CG RAM Address Set" defines the
ASCII code (Bit 3,4,5) and the dot line (Bit 0,1,2)
of the new character. Example demonstrates
creating ASCII code $00.
2.) Doing 8 times the write command "Data Write"
defines line by line the new character. 8th. byte
stands for the cursor line.
3.) The new defined character can be used as a "normal" ASCII code (0..7); use with "DD RAM Address
Set" and "Data Write".
