CONTRAST ADJUSTMENT
VEE
10k 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 builtin 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:
Rgelb/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.

1.) The command "CG RAM Address Set"

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.

3.) The new defined character can be used as
a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".
