CONTRAST ADJUSTMENT
VEE

W
Both displays EA DIP081-CNLED and -CHNLED do have an driving voltage for
3,6k
W
contrast of typ. 4,9V. For 3.3V operation additional -3.3V is required.
-3,3V
Version EA DIP081-CHNLED for ext. temperature range -20..+70°C does have a built-
in temperature compensation; so there's no need for contrast adjustment while operation.
BACKLIGHT
Backlight do need an external resistor limiting the current limitor. Calculation is: R=U/I, so at 5V supply:
R
gelb/grün
=(5,0V-4,1V)/0,15A= 6 Ohm
Caution: do never drive backlight direct with 5V; damage may come suddenly.
CHARACTER SET
Character set shown below is already built in. In addition to that you are able to define up to 8 characters
by yoursself.

CREATING YOUR OWN CHARACTERS
All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in
addition to the 192 ROM fixed codes.
Set CG RAM Address
Data
1.) The command "CG RAM Address Set"
Bit
Adresse
Hex
Hex
defines the ASCII code (Bit 3,4,5) and the
7 6 5 4 3 2 1 0
dot line (Bit 0,1,2) of the new character.
0 0 0 $40
0 0 1 0 0 $04
Example demonstrates creating ASCII
0 0 1 $41
0 0 1 0 0 $04
0 1 0 $42
0 0 1 0 0 $04
code $00.
0 0 1 0 0 $04
2.) Doing 8 times the write command "Data
0 1 0 0 0 0 1 1 $43
X X X
1 0 0 $44
1 0 1 0 1 $15
Write" defines line by line the new
1 0 1 $45
0 1 1 1 0 $0E
character. 8th. byte stands for the cursor
1 1 0 $46
0 0 1 0 0 $04
line.
1 1 1 $47
0 0 0 0 0 $00
3.) The new defined character can be used as
a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".
