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.

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 1 1 $43 0 0 1 0 0 $04 2.) Doing 8 times the write command "Data 0 1 0 0 0 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".
