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 of 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 of +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.
ANALOG 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: BLUE, WHITE, AMBER
All displays are equipped with modern, energy-saving LED illumination. Brightness can be varied
0~100% by command. While the black&white display (J-LW) and the amber one (J-LA) can also be
read with the illumination switched off entirely, the blue-white display (B-LW) needs at least minimal
illumination if it is to be read.
We recommend the black&white or amber version for use in direct sunlight. In all other cases we
recommend the very high-contrast blue-white version.
In 24-hour operation, the illumination of the J-LW and B-LW types should be dimmed or switched off
as often as possible to increase their lifetime. The amber version (J-LA) is also suitable for continuous
use at 100% illumination (MTBF 100,000 hours).
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.
Flashing attributes can be assigned as often as you like. Text and graphics can be combined at any
time. Up to 32 different character sets can be used. 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
PROGRAMMER FOR INTERNAL DATA FLASH MEMORY
The display is shipped fully programmed and with all fonts. The additional programmer 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 USB programmer EA 9778-1USB, which is available as an accessory, will
burn the data/images you have created into the on-board data flash memory (80 kB) permanently.
The programmer runs under Windows and is connected to the PC’s USB interface. It is shipped with
an interface cable and the installation software.

OUTPUTS
The EA eDIP320 offers up to 8 outputs, which can be used to control LEDs, for example. The
configuration pins used depend on the interface selected (RS232, SPI or I²C). The configuration pins
(open drain with internal pullup) are then evaluated as 1=HIGH level.
Each output can be controlled by means of the ‘ESC YW n1 n2’ command. Current can only flow
when the level is at L (open drain with internal pullup). Each output can supply a maximum of 10 mA.
It is thus possible to connect an LED to an output directly. Higher currents can be connected by using
an external transistor.

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 5V (CMOS level)
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.

BAUD RATES
The baud rate is set by means of pins 6, 7 and 8 (baud 0 to 2). The
data format is set permanently to 8 data bits, 1 stop bit, no parity.
RTS/CTS handshake lines are not required. The required control is
taken over by the integrated software protocol (see pages 8 and 9).

RS-485 INTERFACE
With an external converter (e.g. SN75176), the EA eDIP320 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 eDIP320
displays can be operated on a single RS-485 bus by setting addresses.
We recommend the EA 9778-1RS485 board for development.
Addressing:
- Up to eight hardware addresses (0 to 7) can be set by means of pins ADR0 to 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 deselected after power-on.
- Up to 246 fur ther software
addresses can be set by means
of the ‘#KA adr’ command in the
power-on macro (set the eDIP
externally to the address 0).

SPI INTERFACE
If the display is wired as shown below, SP
mode is activated. The data is then transferred
via the serial, synchronous SPI interface.
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 3 MHz.
Note:
The pins DORD, CPOL, CPHA, WUP, 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.
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.

DATA TRANSFER SPI
Via the pins DORD, CPOL and CPHA transfer
parameter will be set.
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 an
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 eDIP320-8 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. Same is with 100kHz operation.

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.
Note:
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

Note:
The pins BA0 to 2, SA0 to 2, DPOM, DPROT and TEST/SBUF have an internal pullup, which is why only the LO level (L=0=GND) is to be
actively applied. These pins must be left open for a Hi level (H=1).
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.

DATA TRANSFER 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 eDIP320-8 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 elapse before the package
is sent again.
The raw data volume per package is limited to 128 bytes (len <= 128).
Commands longer than 128 bytes (e.g. Load image ESC UL...) must be
divided up between a number of packages. All data in the packages are
compiled again after being correctly received by the EA eDIP320-8.
DEACTIVATING THE 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.

TOUCH PANEL (EA EDIP320X-8LWTP VERSIONS)
The -xxxTP versions are shipped with an analog, resistive touch panel. Up to 80 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 16). 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 19, Macro
programming).
TOUCH PANEL ADJUSTMENT
The touch panel is perfectly adjusted and immediately ready for operation on delivery. As a result of
aging and wear, it may become necessary to readjust the touch panel.
Adjustment procedure:
1.
Touch the touch panel at power-on and keep it depressed. After the message “touch adjustment
?” appears, release the touch panel again (or issue the ‘ESC @’ command).
2. Touch the touch panel again within a second for at least a second.
3. Follow the instructions for adjustment (press the 2 points upper left and lower right).
FRAMES AND KEY FORMS
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 GROUPS)
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.

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.
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 8 and 9) 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: ‘##’.
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).

INTEGRATED AND EXTERNAL FONTS
As standard, there are 3 monospaced character sets, 3 proportional character sets and 1 large digit
font integrated in addition to the 8x8 terminal font (font no. 0). The proportional character sets (which
have a narrow “I” and a wide “W”, for example) look better and take up less space on the screen.
Each character can be placed with pixel accuracy, and its height and width can be increased by a
factor of 1 to 8.
A text can be output left justified, right justified or
centered. Rotation in 90° steps is possible (for
vertical installation of the display, for example).
Macro programming permits further fonts to be
integrated (up to 31). All kinds of fonts can be
created using a text editor and loaded using the
eDIP320 compiler *) (the USB programmer
EA 9778-1USB is required).

USING THE 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 come 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.: #GD0,0,319,239,
- 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).

TOP VIEW AFTER 180° ROTATION
The best way to view the EA eDIP320 is diagonally from below (bottom view, 6 o’clock).
The eDIP320 can be installed rotated by 180° to get the top view (12 o’clock).
To correct the contents of the screen, three solder straps (JS, JS1 and JC) have to be resoldered.
Important: Always place all solder straps in the
same position and desolder them cleanly. Short
circuits destroy the eDIP320-8.
Bottom View
If an eDIP320-8 with a touch panel is used, the
touch interpretation must also be changed with the
command ‘ESC AO 1’.
Top View
POWER-DOWN MODE
To save energy (battery operation), you can activate power-down mode by means of the command
‘ESC PD n1’ (see page 15 below). 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 eDIP20 typically requires 150 µA.
Thanks to the integrated suppressor diodes, however, the shunt current can also be 1000 µA and
more.
The suppressor diodes can be deactivated by opening the solder straps J1 and J3. Then powerdown current of typically 20 µA is reached.
Important: When the solder straps J1 and J3 are open, it is essential that the polarity of the display
is correct at all the time: VDD, GND (pin 1 + 2). Even very brief polarity reversal or overvoltage can
damage the display immediately and irreparably.
The eDIP320 can be woken from power-down mode by a level of L at pin 13 (WUP), when the
screen is touched or through the I2C address.

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 (0 to 255) Makro:
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. These
macros are also called by macro processes at defined intervals. Macro processes are not interrupted
when commands are received from the interface or when touch macros are triggered.
Touch macro (1 to 255) TouchMakro:
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.
Power-on macro PowerOnMakro:
Started after power-on. You can switch off the cursor and define an opening screen, for example.
Reset macro ResetMakro:
Started after an external reset (low level at pin 5).
Watchdog macro WatchdogMakro:
Started after a fault/error (e.g. failure).
Brown-out macro BrownoutMakro:
Started after a voltage drop under 3V.
WakeUpPin macro WakeUpPinMakro:
Started after waking from power-down mode at pin 13 (WUP).
WakeUpTouch macro WakeUpTouchMakro:
Start after waking from power-down mode by touch contact (WUP).
WakeUpI²C macro WakeUpI2CMakro:
Started from power-down mode via the I²C bus.
Important: If a continuous loop is programmed in a power-on, reset, watchdog or brown-out macro,
the display can no longer be addressed. In this case, the execution of the power-on macro must be
suppressed. You do this by wiring WUP (power-off: connect pin 13 (WUP) to GND; power-on: open
pin 13 (WUP) again).

CREATING INDIVIDUAL MACROS AND IMAGES
To create your own macros, you need the following:
- To connect the display to the PC, you need the EA 9778-1USB USB programmer, which is available
as an accessory, or a self-built adapter with a MAX232 level converter (see the application example
below).
- ELECTRONIC ASSEMBLY LCD-Tools*), which contains a kit editor, kit compiler and examples
and fonts (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 eDIP320 compiler using F5. This creates
a file called DEMO.DF. If an EA 9778-1USB programmer is also connected or the display is connected
to the PC via a MAX232, this file is automatically burned in the display’s data flash memory. The
eDIP320 compiler recognizes the display regardless of whether the small protocol is switched on.
You will find a detailed description of the programming of the macros together with examples in the
ELECTRONIC ASSEMBLY LCD-Tools*) help system.

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 data flash memory (80 kB) using 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.
You can use the “PICTURE” compiler directive to integrate two monochrome BMPs of equal size for
touch keys, screen masks or flashing images.

MACRO PAGES (MULTILINGUAL CAPABILITY)
There are 16 complete macro sets available in each case for the normal, touch and menu macros
as well as the internal images. By simply

switching the active macro page

WRITE PROTECTION FOR MACRO PROGRAMMING AND FONTS
A LO level at pin 19 (WP) prevents the macros, images and fonts in the data flash memory from
being overwritten inadvertently (so it is highly recommended !).
ADDING MEMORY
The internal data flash memory is 80 kB. That means there is generally enough space for a large
number of icons and macros. However, if a very large number of images (full images, in particular)
or several large character sets are to be stored, it may be necessary to add more memory (max.
8192 kB). This can be done by directly soldering a data flash memory from the AT45DBxxxD-SU
series onto the eDIP320 (see page 18 IC7).
For example: AT45DB041D-SU = 512 kB, AT45DB081D-SU = 1024 kB or AT45DB161D-SU =
2048 kB.
