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.

ANALOGTOUCHPANEL

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.

LEDBACKLIGHT,TYPESBANDJ

Alldisplaysinblue-and-white(B)andblack-and-white(J)areequippedwithamodern, lowpowerconsumption

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

backlightisswitchedoffcompletely,theblue-whitedisplayrequiresaminimumlevelofilluminationtobelegible.

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.

OUTPUT

Beginning with firmware V1.6 and the higher the EA eDIP240 is able to provide up to 7 digital output

for driving an external LED for example.

Depending on the choosen interface mode RS232, SPI or I2C all non used

configuration pins can be used as separate output lines. All lines used for output (open drain with

internal pull-up) are like 1=HIGH level for interface mode configuration.

Each output can be set by command ‘ESC YW n1 n2’ individually. Maximum current is 10mA per line.

Because of internal pull-up construction the max. current is valid for L level only. So theoretically each

line is able drive a LED direct. Larger current need to be amplified by use of a transistor or MOSFET.

DATATRANSFERPROTOCOL(SMALLPROTOCOL)

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 eDIP240-7 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.

Ifthehostcomputerdoesnotreceiveanacknowledgment, atleastonebyte

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 64 bytes (len <= 64).

Commands longer than 64 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 eDIP240-7.

DEACTIVATINGTHESMALLPROTOCOL

TOUCHPANEL(EAeDIP240x-7LWTPonly)

The versions -7xxTP are supplied with an analog resistive touch panel. Up to 60 touch regions

(buttons, switches, menus, bar graph entries), can be defined simultaneously. The fields can be

defined to single-pixel accuracy. The display supports representation using easy-to-use commands

(seepage15). Whenthetouch“keys”aretouched, theycanbeautomaticallyinvertedandanexternal

buzzer (pin 16) can sound, indicating they have been touched. The defined return code of the “key”

is transmitted via the serial interface, or an internal touch macro with the number of the return code is

started (see page 18, Macro programming).

TOUCHPANELADJUSTMENT

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 touching it. 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).

FRAMESANDKEYFORMS

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).

BITMAPSASKEYS

Inadditiontotheframetypes,whichcanbescaledtoanysize,youalsohavetheoption

ofusinganybitmapimages(ineachcase, apairshowingthenot pressedandpressed

statuses) as touch keys or switches.

The LCD-Tools^*)allows you to incorporate your own buttons in the form of images

(compiler statement “PICTURE”). A button always comprises two monochrome

Windows BMPs of the

same size (one bitmap

showing the normal

representation of the

touch key and one

showing the pressed

touch key). The active

area of the touch key is

derived automatically

from the size of the button

bitmaps.

SWITCHESINGROUPS(RADIOGROUP)

Touch switches change their status from ON to OFF and vice versa each time they are touched. A

number of touch switches can be grouped together (command: ‘ESC A R nr’). If a touch switch in an

‘nr’groupisnowswitchedon, allotherbuttonsinthisgroupareautomaticallyswitchedoff. Thismeans

that one button is only ever on at a time.

INTEGRATEDANDEXTERNALFONTS

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). Eachcharactercanbepositionedwithpixel

accuracy and the width and height can be scaled

by a factor of 1 - 4.

Eachtextcanbeoutputleftjustified,rightjustifiedor

centered. 90° rotation e.g. for vertical installation of

the display is also possible. Macro programming

permits additional fonts to be integrated (up to 15).

This is be done with a text editor and programmed

using the LCD-Tools^*)(EA 9777-1USB).

Note:

At pin 20 (SBUF), the display sets a low level to indicate that data is available to be fetched from the internal send buffer.

This line can, for instance, be connected to an interrupt input of the host system.

TERMINALMODE

The display provides a terminal function. When

you switch it on, a cursor flashes in the first line,

indicatingthatthedisplayisreadyforoperation.All

the incoming characters are displayed in ASCII

format on the terminal (exception:

CR,LF,FF,ESC,’#’). To achieve this, a correctly

functioning protocol frame is required (pages 8

and 9) or the protocol must be deactivated (close

solder strap J2, page 8 and 20).

Line breaks are automatic or can be executed by

meansofthe‘LF’character.Ifthelastlineisfull,the

contents of the terminal scroll upward. The ´FF´

character (formfeed) clears 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 a separate output layer and is

thus completely independent of the graphic

outputs.Ifthegraphicsscreenisclearedwith‘ESC

Terminal-Font (Font 0): 8x8 monospaced

DL’, for example, that does not affect the contents

of the terminal window. The terminal font is permanently in ROM and can also be used for graphics

output ‘ESC Z...’ (set FONT no.=0).

USINGTHESERIALINTERFACE

The EA eDIP240-7 can be programmed by means of various integrated commands. Each command

begins with ESCAPE or HASH followed by one or two command letters and some parameters.

There thus are two ways to send 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.: #GD0,0,239,127,

- Strings (text) are written directly without quotation marks and terminated 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 sent directly.

- The x, y coordinates and all the other parameters are transmitted as 8-bit binary values (1 byte).

- Strings (text) are terminated 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).

MACROPROGRAMMING

Single or multiple command sequences can be grouped together in macros and stored in the

EEPROM. You can then start them by using the Run macro commands. There are different types of

macro:

Normal macros (0 through 255)

Thesearestartedbymeansofan‘ESCMNxx’commandviatheserialinterfaceorfromanothermacro.

A series of macros occurring one after the other can be called cyclically (movie, hourglass, multi-page

helptext). TheseautomaticmacroscontinuetobeprocesseduntilacommandisreceivedviaRS-232

or another macro is activated.

Furthermore these macros may be started by "macro processes" as an individual task (from V1.1).

Process macros will not be interupted by any other commands or touch panel use.

Touch macro (1 through 255)

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 through 255)

Started when you choose a menu item or issue an ‘ESC MM xx’ command.

Power-on macro

Started after power-on. You can switch off the cursor and define an opening screen, for example.

Reset macro

Started after an external reset or after a voltage dip under 4.7V (VDD-VSS).

Watchdog macro

Started after a fault/error (e.g. crash).

Brown-out macro

Started after a voltage dip <4V.

Important: If a continuous loop is programmed in the power-on, reset or watchdog macro, the display

cannolongerbeaddressed. Inthisevent, executionofthepower-onmacromustbesuppressed. This

is achieved by wiring DPOM appropriately.

PowerOff - connect pin 13 (DPOM) to GND - PowerOn - disconnect pin 13 again.

MEMORYEXPANSION

The size of the internal EEPROM memory is 32 kB. Generally, this allows sufficient space for a large

number of images and macros. If, however, a very large number of images (in particular full-size

images) are to be stored, it can be necessary to expand the memory. The memory capacity can be

doubled by directly connecting a standard EEPROM of the 24C256 series. It is connected over pins

17, 18 and 19 (I2C adress $A6) or can be placed direct as U12 (see drawing on page 20).

IMAGESSTOREDINEEPROM

To reduce the transmission times at the interface or to save storage space in the processor system,

up to 256 images can be stored in the internal EEPROM. They can be called using the “ESC U I”

command or from within a macro. Any images in Windows BMP format (monochrome images only)

can be used. They can be created and edited using commercial software such as Windows Paint or

Photoshop (only black and white = 1 bit).

CREATINGYOUROWNMACROSANDIMAGES

To create your own macros, you need the following:

- the additional EA 9777-1USB programmer (available as an accessory) or self-created adaptor like

application example below,

- the ELECTRONIC ASSMBLY LCD-Tools^*)software; this contains a KIT-Editor, KIT-Compiler,

Simulator, and examples and fonts (for Windows PCs)

- a PC with a serial port USB or COM

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.

IfthemacrosaredefinedusingtheKITEditor, theKITCompilerisstartedbypressingF5. Thiscreates

a file with the name DEMO.EEP which immediately shows the results in a simulator window (virtual

display). If display is connected via USB programmer EA 9777-1USB or application below, this file

is then automatically burned into the display’s EEPROM. The KIT Compiler recognizes the display

with or without the small protocol being activated.

The actual programming operation only takes a few seconds, and you can then use your user-defined

macros and images on the display immediately. You will find a detailed description of how to program

macros along with examples in the online Help for the ELECTRONIC ASSEMBLY LCD-Tools^*)

software.

Notes on handling and operation

- LC dispalys are designed for hand soldering only.

Reflow and wave soldering may destroy lcd

immediately

- The following can lead to the electronic

destruction of the module: cross-polarity or

overvoltage of the power supply, overvoltage or

cross-polarity or static discharge at the inputs,

short-circuits at the outputs.

ALUMINIUMBEZEL

- The power supply must be disconnected before the

module is removed. All inputs must also be free of

voltage.

- The display and the touch screen are made of

plastic and must not come into contact with hard

objects. The surfaces can be cleaned with a soft

cloth. No solvents may be used.

- The module is designed only for operation within

buildings. Additional measures must be taken to

allow operation in the open air. The maximum

temperature range of -20 through +70°C must not

be exceeded. The module may not operate

correctly and may fail if used in a humid

environment. The display must be shielded from

direct sunlight.
