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.

RS-232 INTERFACE
If the display is wired as shown
below, the RS-232 interface is
selected. The pin assignment is
specified in the table on the right.
The RxD and TxD lines lead
CMOS level (VDD) to a
microcontroller, for example, for
direct connection.
If “genuine” RS-232 levels are
required (e.g. for connection to a
PC), an external level converter
(e.g. MAX232) is required.

Note:
The pins BAUD 0 to 2, ADR 0 to 2, DPOM,
DPROT and TEST/SBUF have an internal
pullup, which is why only the LO level
(0=GND) is to be actively applied. These
pins must be left open for a hi level.
For RS232 operation (without
addressing) the pins ADR 0 to ADR 2
must be left open.
On pin 20 (SBUF) the display indicates
with a low level that data is ready to be
retrieved from the internal send buffer.
The line can be connected to an interrupt
input of the host system, for example.

APPLICATION EXAMPLE „REAL“ RS-232 INTERFACE
The eDIP fits for direct
connection to a RS-232
interface with CMOS
level (VDD).
If you have an interface
with ±12V level, an
external levelshifter is
needed.
Application note
APPLICATION EXAMPLE: RS-485 INTERFACE
With an external converter (e.g.
SN75176), the EA eDIP can be
connected to a 2-wire RS-485
bus. Large distances of up to
1200 m can thus be
implemented (remote display).
Several EA eDIP displays can
be operated on a single RS-485
bus by setting addresses.
Application note
Adressing:
- Up to eight hardware addresses (0 to 7) can be set by means of Pins ADR0..ADR2
- The eDIP with the address 7 is selected and ready to receive after power-on.
- The eDIPS with the addresses 0 to 6 are deselcted after power-on
- Up to 246 further software addresses can be set by means of the ‘#KA adr’ command in the power-on macro (set eDIP
externally to address 0)
APPLICATION EXAMPLE: USB INTERFACE
With an external converter (e.g. FT232R from FTDI) the eDIP can be connected to an USB-Bus.
Virtual-COM-Port drivers are available for different Systems on the FTDI Homepage:

DATATRANSFER SPI
Write operation: a clock rate up to 100 kHz is allowed
without any stop. Together with a pause of 100 µs
between every data byte a clock rate up to 3 MHz can
be reached.
Read operation: to read data (e.g. the „ACK“ byte) a
dummy byte (e.g . 0xFF) need to be sent.
Note that the EA eDIP for internal operation does need
a short time before providing the data; therefore a short
pause of min. 6µs (no activity of CLK line) is needed for
each byte.
Application note

I²C-BUS INTERFACE
If the display is wired as shown
below, it can be operated directly
on an I²C bus.
8 different base addresses and 8
slave addresses can be selected
on the display.
Data transfer is possible at up to
100 kHz. However, if pauses of at
least 100 µs are maintained
between the individual bytes
during transfer, a byte can be
transferred at up to 400 kHz.

IN- AND OUTPUTS
The eDIP128-6 has 8 digital in- or outputs (CMOS level, grounded). They can be redefined freely.
Inputs
As status on delivery, all ports are defined as inputs. Each input provides an internal
20..50 kΩ pull-up resistor, so it is possible to connect a key or switch directly between
input and GND. The inputs can be queried and evaluated directly via the serial
interface („ESC Y R“).
In addition to that every port change may start an individual port - or bit- macro (see p.
24). The command "ESC Y A 1" activates automatic port query. Every alteration of inputs firstly calls
bit macros and afterwards port macros. If there is no definied macro, the new status is transfered into
the send buffer (refer to p. 18).
Note: The logic circuitry is designed for slow operations; in other words, more than 3 changes per
second cannot be easily executed.
Outputs
The command "ESC Y M number" redefines one or several inputs as outputs. In this case the more
significant inputs are used as outputs.
'ESC Y M 3' switches IN8, IN7 and IN6 as outputs OUT1, OUT2 and OUT3
for example.
Each line can be controlled individually using the „ESC Y W“ command. A
maximum current of 10mA can be switched per line. This give the opportunity
to drive a low power LED in direct way. To source higher current please use
an external transistor.
EXTENDED OUTPUTS
It is possible to connect 1 to 32 chips like 74HC4094 to the eDIP (OUT1...OUT3), this is why it is
attainable to have 8 to 256 additional outputs. The command "ESC Y E n1 n2 n3" (see p. 16) provides
a comfortable way to control the outputs.

TOPVIEW ANDTWISTED MOUNTING
The prefered view of the eDIP128 is bottom view, (6 o'clock).
The eDIP can be mounted turned around 180° to gain a top view display (12 o'clock). To set the
viewing direction you have to run (e.g. in PowerOnMacro) the command 'ESC DO 2' (refer to p. 13).
In addition it is possible to mount the display turned with 90° or 270° to gain a portrait mode display
with 64x128 pixels.
0°: 'ESC DO 0'
90°: 'ESC DO 1'
180°: 'ESC DO 2'
270°: 'ESC DO 3'
POWER DOWN MODE
To save energy (battery operation), you can activate one of three power-down modes by means of the
command ‘ESC PD n1’ (see page 15 below).
Mode 0 (25µA): The LED illumination is switched off, and the contents of the display become
invisible although they are still there. In power-down mode including suppressor
diodes, the eDIP128 requires up to 1000 µA (delivery state). The suppressor diodes
can be deactivated by removing the two 0Ω resistors. Then powerdown current of
typically 25 µA is reached. They are labeled with Rpd.
Important: When deactivating the suppressor diodes, it is essential that the polarity of
the display is correct all the time: GND, VDD (pin 1 + 2). Even very brief polarity reversal
or overvoltage can damage the display immediately and irreparably.
Mode 1 (1mA): The LED illumination is switched off, the contents of the display stay visible. Current
consumption is reducing to 1mA. This power down mode is mainly usable with the
versions EA eDIP128W with positive display, because they are readable without
backlight.
Mode 2 (4mA): The LED illumination stays on and the display content is readable. The current
consumption reduces to 3-4mA plus adjusted LED current. Therefore you can use
the eDIP in dark surroundings and dimmed illumination under e.g. 10mA.
The eDIP128 can be woken up from power down mode with a low level on pin 13 (WUP), or the
adressing via I²C.
In additon the eDIP128 can be woke up by using the touchpanel (independed from position).
After wake up, special WakeUpMacros can be used (refer to p. 24).

DATATRANSFER PROTOCOL(SMALL PROTOCOL)
The protocol has an identical structure for all 3 interface types: RS-232, SPI and I²C. Each data transfer is
embedded in a fixed frame with a checksum (protocol package). The EA eDIP128-6 acknowledges this
package with the character <ACK> (=$06) on successful receipt or <NAK> (=$15) in the event of an incorrect
checksum or receive buffer overflow. In the case of <NAK>, the entire package is rejected and must be sent
again. Receiving the <ACK> byte means only that the protocol package is ok,
there is no syntax check for the command.
Note: It is neccessary to read the <ACK> byte in any case. If the host
computer does not receive an acknowledgment, at least one byte is lost. In
this case, the set timeout has to elapsed before the package is sent again.
The raw data volume per package is limited to 255 bytes (len <=255).
Commands longer than 255 bytes (e.g. Load image ESC UL...) must be split
up between a number of packages. All data in the packages are compiled
again after being correctly received by the EA eDIP.
DEACTIVATINGTHE SMALL PROTOCOL
For tests the protocol can be switched off with an L-level at pin 17 = DPROT.
In normal operation, however, you are urgently advised to activate the
protocol. If you do not, any overflow of the receive buffer will not be
detected.

TERMINAL MODE
When you switch the unit on, the cursor flashes in the
first line, indicating that the display is ready for
operation. All the incoming characters are displayed
in ASCII format on the terminal (exception:
CR,LF,FF,ESC,’#’). The prerequisite for this is a
working protocol frame (pages 10 and 11) or a
deactivated protocol.
Line breaks are automatic or can be executed by
means of the ‘LF’ character. If the last line is full, the
contents of the terminal scroll upward. The ‘FF’
character (page feed) deletes the terminal. The
character ‘#’ is used as an escape character and thus
cannot be displayed directly on the terminal. If the
character ‘#’ is to be output on the terminal, it must be
transmitted twice: ‘##’.
Terminal-Font (Font 0): 8x8 monospaced
The terminal has its own level for displaying and is thus entirely independent of the graphic outputs.
If the graphics screen is deleted with ‘ESC DL’, for example, that does not affect the contents of
the terminal window. The terminal font is fixed in the ROM and can also be used for graphic outputs
‘ESC Z...’ (set FONT nr=0).
FILL PATTERN
A pattern type can be set as a parameter with various
commands. In this way, for example, rectangular
areas and bar graphs can be filled with different
patterns. There are 16 internal fill patterns available.
USINGTHE SERIAL INTERFACE
The operating unit can be programmed by means of various integrated commands. Each command
begins with ESCAPE followed by one or two command letters and then parameters. There are two
ways to transmit commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters follow directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
character (such as a comma ‘,’), also after the last parameter e.g.: #GD0,0,159,103,
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
(hex: $0A).
2. Binary mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are transmitted directly.
- The coordinates xx and yy are transmitted as 16-bit binary values (first the LOW byte and then the
HIGH byte).
- All the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are concluded with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode.
The commands require no final byte, such as a carriage return (apart from the string $00).).

TOUCH PANEL(ONLY EAeDIP128x-6xxTP)
The -xxxTP versions are shipped with an analog, resistive touch panel. Up to 40 touch
areas (keys, switches, menus, bar graph inputs) can be defined simultaneously. The
fields can be defined with pixel accuracy. The display supports user-friendly
commands (see page 17). When the touch “keys” are touched, they can be
automatically inverted and an external tone can sound (pin 16), indicating they have
been touched. The predefined return code of the “key” is transmitted via the interface,
or an internal touch macro with the number of the return code is started instead (see
page 22, Macro programming).
FRAMES AND KEY SHAPES
A frame type can be set by using the Draw frame or Draw frame box command or by
drawing touch keys. 18 frame types are available (0 = do not draw a frame). The frame
size must be at least 16x16 pixels.
BITMAPS AS KEYS
Apart from the frame types, which are infinitely scalable, it is also possible to use
bitmaps (2 each, for not printed and printed) as touch keys or touch switches. You can
use ELECTRONIC ASSEMBLY LCD-Tools*) to integrate your own buttons as images
(“PICTURE” compiler statement). A button always consists of two monochrome
Windows BMPs of equal size (one bitmap to display the touch key in its normal state
and one for when it is pressed). The active area of the touch key automatically results
from the size of the button bitmaps.
SWITCHES IN GROUPS (RADIO GROUP)
Touch switches (radio buttons) change their status from ON to
OFF or vice versa each time they are touched. Several touch
switches can be included in a group (‘ESC A R nr’ command).
If a touch switch in the group ‘nr’ is switched on, all the other
touch switches in this group are automatically switched off.
Only one switch is ever on.

RESPONSES OFTHE EA EDIP128-6VIA SERIAL INTERFACE
The table below contains all response codes. Some response data will come automatically some
others on request. In addition to that with command 'ESC SB ...' user is able to transmit individual data
packages. All reponses are placed into the sendbuffer. With the smallprotocol command ’Request for
content of send buffer’ (see page10) the host can read out the sendbuffer. This can be done per polling,
alternatively pin 20 ’SBUF’ shows with Low-level that data is ready to transmit.

PRELOADED FONTS
Apart from the 8x8 terminal font (font no. 8), 3 additional monospaced fonts, 3 proportional fonts and 1 large
numeric font are integrated as standard. The proportional fonts result in a more attractive appearance, and at
the same time require less space on screen (e.g. the “i” is narrow and the “W” is wide). Each character can
be positioned with pixel accuracy and the width and height can be scaled. Each text can be output left justified,
right justified or centered. 90° rotation is also possible. Macro
programming permits additional fonts to be integrated (up to
15). This is done using the LCD-Tools*) (EA 9777-2USB).

Compile statement "WinFont:"
It is possible to raster TrueType-Fonts in different sizes whitch can be
used. A doubleclick to the fontname within the KitEditor opens the font
selection box. To simplify the use of fonts, there is the possibilty of an edit
box. If you output a string with KitEditor (e.g. #ZL 5,5, "Hello"), you can
perform a double click on the string to open it. Now you can select the
desired characters. This is mainly recommended using cyrillic, asian or
symbol fonts.
integrated fonts in delivery state
In that way, the KitEditor automatically places the right ASCII-Code.
Alternativly you can use instead of the quotation mark curly brackets (e.g. #ZL 5,5, {48656C6C6F}).

DISPLAY BLINK MODE
After power on or the command 'ESC DG 0' the eDIP128 is in blink mode.
Two picture contents are alternatly shown in an adjustable period.
Blink attributs are set by the commands 'ESC ZB, UB, GB n1':
n1=0: no blink
n1=1: On/Off blink
n1=2: blink inverted
n1=3: Off/On blink (phase shifted)
Between strings ('ESC ZL,ZC,ZR. ..), flashing can be activated locally:
Strings between two ‘~’ ($7E) mean blink on/off.
Strings between two ‘&’ ($26) mean blink off/on phase shifted.
Strings between two '@' ($40) mean blink inverted.
In addition you can assign or delete postly an rectangle area a blink mode, by using the command
'ESC Q...'

MACRO PROGRAMMING
Single or multiple command sequences can be grouped together in macros and stored in the data
flash memory. You can then start them by using the Run macro commands. There are different types
of macro (compiler directive marked in green letters):
Normal macro Macro:
These are started by means of an ‘ESC MN xx’ command via the serial interface or from another
macro. A series of macros occurring one after the other can be called cyclically (movie, hourglass,
multi-page help text). These automatic macros continue to be processed until either a command is
received via the interface or a touch macro with a corresponding return code is activated.
Touch macro TouchMacro:
Started when you touch/release a touch field (only in versions with a touch panel - TP) or issue an
‘ESC MT xx’ command.
Menu macro (1 to 255) MenuMakro:
Started when you choose a menu item or issue an ‘ESC MM xx’ command.
Bit macro BitMacro:
will be started by a single line IN 1..8 (bit) will change or by command 'ESC MB xx'. Bit- Macro 1..8 are
good for falling edge and Bit Macro 9..16 are good for rising edge at input 1..8. It is possible to change
the assignment between Bitmacro and intput with command ‘ESC YD n1 n2 n3’ (see page 17).
Port macro PortMacro:
These are started when voltage (binary) is applied to IN 1..8 or by command 'ESC MP xx'.
Power-on-macro PowerOnMacro:
Started after power-on. You can switch off the cursor and define an opening screen, for example.
Reset-macro ResetMacro:
Started after an external reset (low level at pin 5).
Watchdog-macro WatchdogMacro:
Started after a fault/error (e.g. failure).
Brown-out-macro BrownOutMacro:
Started after a voltage drop under 3.0V (typ.).
Important: If a continuous loop is
programmed in a power-on, reset, watchdog
Wake-up-pin-macro WakeupPinMacro:
Started after wake up from power-down-mode with pin or brown-out macro, the display can no

STORING IMAGES IN THE DATA FLASH MEMORY
To reduce the transmission times of the interface or to save storage space in the processor system,
up to 256 images can be stored in the internal EEPROM with the “PICTURE” compiler directive. They
can be called using the “ESC U I” command or from within a macro.
All images in the Windows BMP format (monochrome images only) can be used. They can be created
and edited using widely available software such as Windows Paint or Photoshop or the bitmap editor
shipped with the product.
CREATING INDIVIDUAL MACROS AND IMAGES
To create your own fonts, images, animations and macros you need the following:
- To connect the display to the PC, you need the EA 9777-2USB USB evaluation board, which is
available as an accessory, or a self-built adapter with a MAX232 level converter (see the application
example on page 5).
- ELECTRONIC ASSEMBLY LCD-Tools*), which contains a kiteditor, bitmapeditor, ediptftcompiler,
fonts, images, border, pattern and examples (for Windows PCs)
- A PC with an USB or serial COM interface
To define a sequence of commands as a macro, all the commands are written to a file on the PC (e.g.
DEMO.KMC). You specify which character sets are to be integrated and which command sequences
are to be in which macros. If the macros are defined using the kit editor, you start the eDIP compiler
using F5. This creates a file called DEMO.EEP. If an EA 9777-2USB evaluation board is also
connected or the display is connected to the PC via a MAX232, this file is automatically burned in the
display’s data memory.
You can send the created macrofile *.EEP with any other system to the EA eDIP128-6. All
programming commands are inside this file, so you only need to send the content of the *.df file (via
RS232, SPI or I2C with smallprotocol in packets) to the EA eDIP128-6.
