GENERAL
The EA eDIP series of displays are the world’s first displays with integrated intelligence. In addition
to a variety of integrated fonts that can be used with pixel accuracy, they offer a whole range of
sophisticated graphics functions.
They are controlled via one of the 3 integrated interfaces: RS-232, SPI or I²C. The displays are
“programmed” by means of high-level language-type graphics commands. There is no longer any
need for the time-consuming programming of character sets and graphics routines. The ease of use
of this display with its touch panel dramatically reduces development times.
HARDWARE
The display is designed to work at an operating voltage between +3.3V to +5V.
Data transfer is either serial and asynchronous in RS-232 format or synchronous via the SPI or I²C
specification. To improve data security, a simple protocol is used for all types of transfer.
ANALOGUE TOUCH PANEL
All versions are also available with an integrated touch panel: You can make entries and menu or bar
graph settings by touching the display. The labeling of the “keys” is flexible and can also be changed
during runtime (different languages, icons). The drawing of the individual “keys” and the labeling is
handled by the integrated software.
LED ILLUMINATION
All displays are equipped with modern, energy-saving LED illumination. Brightness can be varied
0~100% by command.
In 24-hour operation, the illumination should be dimmed or switched off as often as possible to increase
their lifetime.
SOFTWARE
This display is programmed by means of commands, such as Draw a rectangle from (0,0) to (319,239) .
No additional software or drivers are required. Strings and images can be placed with pixel accuracy.
Text and graphics can be combined at any time. Different character sets can be used at same time.
Each character set and the images can be zoomed from 2 to 8 times and rotated in 90° steps. With the
largest character set, the words and numbers displayed will fill the screen.
ACCESSORIES
Evaluation-Board (Programmer) for internal data flash memory
The display is shipped fully programmed and with all fonts. The additional Evaluation-Board is thus
generally not required.
However, if the internal character sets have to be changed or extended, or if images or macros have
to be stored internally, the Evaluation-Board EA 9777-2USB, which is available as an accessory, will
burn the data/images you have created into the on-board data flash memory (4 MB) permanently.
The Evaluation-Board runs under Windows and is connected to the PC’s USB interface. It is shipped
with an interface cable and the installation software. The Evaluation-Board is equipped with serveral
LEDs, pushbottons and potentiometer to test all peripherial modes of the eDIP.
Interface-Expansion for Evaluation-Board:
Wtih the expansion EA 9777-2PE for the Evaluation-Board all interfaces of the display are made
available with the help from small adapter boards: RS-232, RS-485, SPI, I²C, RS-232 (CMOS level).
Further information you will find in the datasheet of the Evalution-Board.
