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

Clears all display and returns the cursor
to the home position (Address 0).
Returns the Cursor to the home
position (Address 0). Also returns the
display being shifted to the original
position. DD RAM contents remain
unchanged.
Sets the Cursor move direction and
specifies or not to shift the display.
These operation are performed during
data write and read.
Sets ON/OFF of all display (D) cursor
ON/OFF (C), and blink of cursor position
character (B).
Moves the Cursor and shifts the display
without changing DD RAM contents.
Sets interface data length (DL) number
of display lines (N) and character font
(F).
Sets the CG RAM address. CG RAM
data is sent and received after this
setting.
Sets the DD RAM address. DD RAM
data is sent and received after this
setting.
Reads Busy flag (BF) indicating internal
operation is being performed and reads
address counter contents.
Writes data into DD RAM or CG RAM
Reads data from DD RAM or CG RAM
