LED Backlight
Standard display EA DIPS082-HN is reflective, non-backlighted version. Module with part number
EA DIPS082-HNLED comes with yellow/green LED backlight. Power consumption for backlight is
50mA typ. and 80mA max. Backlight is permanent switched on.
For individual use LED backlight can be switched on and off after doing the following modification:
Remove series resistor R5 and close solder link LB. Now a positive voltage at pin 7 (D0) powers
Anode of backlight direct. To limit LED-current an external series resistor is required (R
Ext.
= 0,8V /
I
LED
). Please note that in this case display interface is 4-bit mode only !

Character set
Below shown character set is already built in. Additionally 8 self defined characters can be
attached.
CREATING YOUR OWN CHARACTERS
All character display modules offered in this catalogue, are able 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 dot line (Bit
0,1,2) of the new character. Example
demonstrates creating ASCII code $00.
2.) Doing 8 times the write command "Data Write"
defines line by line the new character. 8th. byte
stands for the cursor line.
3.) The new defined character can be used as a
"normal" ASCII code (0..7); use with "DD RAM
Address Set" and "Data Write".
