GENERAL

The EA eDIP240-7 is the world’s first display with integrated intelligence! As well as a number of built-in fonts

which can be used with pixel accuracy it also features a whole range of sophisticated graphics functions.

Supplied with 5V, the display is ready for operation immediately. It is controlled via one of the 3 integrated RS-

232, SPI or I²C interfaces.

Graphics commands similar to high-level languages are used for programming. 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 reduces development time dramatically.

HARDWARE

The display is designed to work with an operating voltage of +5V. Data transfer is either serial and

asynchronous using the RS-232 format or synchronous using the SPI or I²C specification. A simple protocol

is used for all data transfer variants to improve data reliability.

ANALOGTOUCH PANEL

The EA eDIP240B-7LWTP and EA eDIP240J-7LWTP versions are equipped 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 BACKLIGHT,TYPES B AND J

All displays in blue-and-white (B) and black-and-white (J) are equipped with a modern, low power consumption

LED backlight. Whereas the black&white and the amber-colored display can still be read even when the

backlight is switched off completely, the blue-white display requires a minimum level of illumination to be legible.

The backlight can be switched off with a software command and the brightness can be adjusted.

We recommend the black&white version for use in direct sunlight. For all other applications, we recommend

the high-contrast, blue-white version.

Note that the white LED backlight is subject to aging. That means switching off or dimming backlight is a must

for 24-hour-applications. Not so for the amber backlight.

SOFTWARE

The display is programmed by means of commands, such as

Draw a rectangle from (0,0) to (64,15). No

additional software or drivers are required. Strings can be placed withpixel accuracy. Flashing attributes can

be assigned as often as you like – for graphics as well. Text and graphics can be combined at any time. Up

to 16 different character sets can be used. Each one can be zoomed from 2 to 4 times. 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 EEPROM (32/64 kB) 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 (included in the Starter-Kit):

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.
