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.

The displays are ready for operation immediately with an operating voltage range of +3.3V..+5V. 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 range of +3.3V..+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, B- ANDW-TYPES

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

consumption LED backlight. Whereas the black&white 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.

SOFTWARE

This 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 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 EEPROM (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.
