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:

R

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
