BACKLIGHT
Using the LED backlight requires an current source or external current-limiting resistor. Forward
voltage for white LED backlight is 3.0~3.6V. Please take care of derating for T
a
>+25°C
Attention: Do never drive backlight directly to 5V; this may damage backlight immediately !
The blue display cannot be read without backlight. For direct sunlight we suggest to use the J-type.

CHARACTER SET
Beside there's a copy of built.in character set. In
addition to that up to 8 individual character can
be created.
CONTRAST ADJUSTMENT
Contrast will be set by pin 3 (VCI).
Module EA DIP204 comes with built-in
temperature compensation for -20..+70°C as a
standard; any contrast adjustment while
operation is no longer required.

CREATING YOUR OWN CHARACTERS
All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in
addition to the 240 ROM fixed codes.

as a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".

SERIAL MODE SPI
Factory set for interface is parallel with 4 bit or 8 bit data bus. Alternative module can be programmes
with serial data stream. For that solder link
4/8
has to be opened and closed to
SPI
side. Harware
specification for serial operation mode is written down in user manual for KS0073:
http://www.lcd-
module.de/eng/pdf/zubehoer/ks0073.pdf.
Software for initialisation and programming keeps the
same.
