PINOUT
CONTRAST ADJUSTMENT
Both displays EA DIP081-CNLED and -CHNLED do have an driving voltage for
contrast of typ. 4,9V. For 3.3V operation additional -3.3V is required.
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:
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.
