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 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.
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. Depending on the field of aplication, you can use either the
anolgue resitive version, designed for the use with pens, thick gloves, or the capacitive version with
its immune hard glas surface.
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
Thisdisplay isprogrammed bymeans ofcommands, suchas
Drawa rectanglefrom (0,0) to (799,479) .
No additional software or drivers are required. Strings and images can be placed withpixel 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 (EA EVALeDIPTFT70) to write to internal data flash memory
The display is shipped fully programmed, 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 9777-3USB, which is available as an accessory, will
burn the data/images you have created into the on-board data flash memory (8 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, push buttons and potentiometer to test all peripherial modes of the eDIP.
Interface-Expansion for Evaluation-Board EA 9777-2PE (included in the Starter Kit):
With the expansion EA 9777-2PE for the Evaluation-Board all interfaces of the display are made
available with the help from small adaptor 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 (5V) for direct connection to a
microcontroller for example.
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.
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 10 and 11).

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 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:
http://www.ftdichip.com/drivers/vcp.htm .
APPLICATION EXAMPLE „REAL“ RS-232 INTERFACE
The eDIP fits for direct
connection to a RS-232
interface with CMOS
level (5V).
If you have an interface
with ±12V level, an
external levelshifter is
needed.
Addressing:
- 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)

SPI INTERFACE
If the display is wired as
shown below, SPI mode is
activated.
The data is then transferred
via the serial, synchronous
SPI interface.
The transfer parameter will be
set via the pins DORD, CPOL
and CPHA.
Note:
The pins DORD, CPOL, CPHA,
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.
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
Write operation: a clock rate up to 200 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.

I²C-BUS INTERFACE
If the display is wired as shown
below, it can be operated directly to
the 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.
DATA TRANSFER I²C INTERFACE
principle I2C-bus transfer:
-I²C-Start
- Master-Transmit: EA eDIP-I²C-address (e.g. $DE), send smallprotocol package (data)
- I²C-Stop
-I²C-Start
- Master-Read: EA eDIP-I²C-Address (e.g. $DF), read ACK-byte and opt. smallprotocoll package (data)
- I²C-Stop
Read operation: for internal operation the
EA eDIP does need a short time before
providing the data; therefore a short pause of
min. 6µs is needed for each byte (no activity of
SCL line).
Note:
The pins BA0..2, SA0..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.

DIGITAL INPUT AND OUTPUT
The EA eDIP is featured with 8 digital input and 8 digital output lines (CMOS level,
grounded).
8 outputs (Pin 33-40)
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.
8 inputs (Pin 41-48)
Each input provides an internal 20..50 kΩpull-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. 30).
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. 21).
Note: The logic circuitry is designed for slow operations; in other words, more than 3 changes per
second cannot be easily executed.
ANALOGUE INPUT AIN1 AND AIN2 (PIN 31+32)
For analogue measurement 2 inputs with a range of 0..+5V are available. Each input is grounded
(GND) and DC impedance is 1MΩ. Please make sure that only positive voltages will be supplied
there. Internal resolution is 10 Bit, equal to a 3-digit DVM modul. Linearity (after adjustment) is around
0.5%.
Adjustment
Analogue inputs are not calibrated when shipped out. A procedure for adjustment may be like that:
1.) Put a well known voltage within a range of 2V-VDD to analogue input (example: 3,0V, AIN1)
2.) Run command for calibration (see page 16). Example: „ESC V @ 1 3000“.
Each input query can be done via serial interface or directly shown on display (as digits or bargraph
in various colors and sizes).
Best way for direct visualisation are Process-macros or one of Analogue-macros (e.g. starting at every
voltage change, or above/below a limit).
Both input lines are scaleable from 0 to ±9999.9. Scaling will be done via definition at 2 voltages
„value1=string1;value2=string2“ (see table on page 16).
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. 17) provides
a comfortable way to control the outputs.

without prior notice. Printing and

EXTERNAL KEYBOARD
A keyboard (anything from individual keys to a 8x8 matrix keyboard) can be connected to the I/O- ports.
The command ‘ESC Y M n1 n2 n3’ defines the count of input lines (n1=1..8) and output lines (n2=1..8).
n3 set debounce function with 10ms steps (n3=0..15). Please note that count of digital input and output
lines will be reduced while connecting an external keyboard at the same port.
Each key is connected with 1 output and 1 input. All inputs are terminated with a 20..50kΩpull-up
resistor. For double-keystroke function decoupling of outputs is necessary. For that please use
schottky diodes (e.g. BAT 46).
Transmitting the keystrokes
At each keystroke, the associated key number (1..64) is transmitted or if a corresponding Matrix-
Macro is defined, Matrix-Macro will be started. The release of the key is not transmitted. If the release
of the key is to be transmitted as well, this can be done by defining Matrix-Macro no. 0.
(see page 21: Responses of EA eDIP)
Calculating of key numbers:
2x2 Matrix 1x4 Matrix 4x0 Matrix 4x4 Matrix
Key_number = (output-1) * count_of_inputs + input (output = MOx, input = MIx).
Examples
- 2x2 matrix: Command ‘ESC Y M 2 2 ..’ defines the 2x2 matrix. Keypad will need input lines MI1, MI2
and output lines MO1, MO2. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 6 input and 6 output lines remain free for other requirements.
- 1x4 matrix: Command ‘ESC Y M 1 4 ..’ defines the 1x4 matrix. Keypad will need output lines
MO1..MO4 and a single input line MI1. With that connection 7 input and 4 output lines
remain free for other requirements.
- 4x0 matrix: Using one single output only (physically 4x1 Matrix), all keys can switch to GND. So no
output line is necessary and command ‘ESC Y M 4 0 ..’ defines 4 input lines onyl. With
that connection 4 input and 8 output lines remain free for other requirements.
- 4x4 matrix: Command ‘ESC Y M 4 4 ..’ defines the 4x4 matrix. Keypad will need input lines MI1..MI4
and output lines MO1..MO4. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 4 input and 4 output lines remain free for other requirements.

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 eDIPTFT70-A
acknowledges this package with the character <ACK> (=$06) on successful receipt or <NAK> (=$15)
inthe event ofan incorrect checksumorreceive buffer overflow.In the caseof <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 255 bytes (len <=
255). Commands longer than 255 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
eDIP.
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
toactivate the protocol.Ifyou do not,any overflow ofthe receive buffer will
not be detected.

BUILDING THE SMALL PROTOCOL PACKAGES
<DC1> = 17(dez.) = $11
<ACK> = 6(dez.) = $06
len = count of user data (without <DC1>, without checksum bcc)
bcc = 1 byte = sum of all bytes incl. <DC1> and len, modulo 256
The user data is transferred framed by <DC1>,
the number of bytes (len) and the checksum
(bcc). The display responds with <ACK>.
The command sequence <DC2>, 1, S, bcc

If the most recently requested package
contains an incorrect checksum, the entire
package can be requested again. The reply can
then be the contents of the send buffer (<DC1>)
or the buffer/protocol information (<DC2>).
This is how the maximum package size that can
be sent by the display can be limited. The default
setting is a package size with up to 128 bytes of
user data. The timeout can be set in increments
of 1/100 seconds. The timeout is activated
when individual bytes get lost. The entire
package then has to be sent again.
This command can be used to select or
deselect the eDIP with the address adr.

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.: #GD0,0,799,479,
- 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).
Terminal-Font 2: 8x16
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 or a deactivated protocol (see
pages 10 and 11).
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 size of the terminal-
window can be set by command 'ESC TW'.
Attention: 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.

TOUCH PANEL
The Version EA eDIPTFT70-ATP is shipped with an analog, resistive touch panel, the version
EA eDIPTFT70-ATC with a capacitive touch panel. Up to 100 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. 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.
