DOGXL240-7 GRAPHIC

PINOUT

The EA DOGXL240-7, a 240x128 dots graphics

display, is a new addition to ELECTRONIC

ASSEMBLY’s EA DOG series. It, too, has pins that

allow it to be mounted quickly and easily.

CONTRAST ADJUSTMENT

The contrast can be set by means of a command

for all the displays in theEA DOGXL- Series. iThe

contrast setting of the display must be set once

by the software, and is then kept constant

throughout the entire operating temperature range

(-20..+70°C), thanks to the integrated temperature

compensation.

LED-BACKLIGHT

3 different variants are available for individual backlighting: white, amber and a duo-color green/red

version.

With the amber backlight, there are 3 separate LED paths containig 5 parallel LEDs, that can be

switched in parallel or in series to suit the system’s voltage.

With the white backlight, there are 3 separate LED paths containig 3 LEDs in series. To operate the

backlight, we recommend a current source (e.g. CAT4238TD).

The duo-color backlight has common anode and two terminals for driving the red and / or the green

color.

The operating life of the amber and green/red backlights is 100,000 hours. The LEDs of the white

backlight are high qualitiy NICHIA LEDs. To achieve the life-time of 100k hours, we recommend dimming

or switching them off whenever possible.

Important: Do never connect the backlight LEDs directly to a 5 V/3.3 V supply as this will immediately

destroy the LEDs. Always use a current source. Please note that derating applies at temperatures

exceeding +25°C.

4 DIFFERENT TECHNOLOGIES

See below for an overview of available technologies, combinations with available backlights and

their usability:

3 DIFFERENT BACKLIGHTS

Three different backlight colors are available to match equipments design as much as possible. The

most effective and brightest one is the white one EA LED94X67-W.

CHARACTER SET AND FONT EDITOR (ACCESSORY)

With the ordering code EA USBSTICK-FONT a memory stick comes with various character sets,

especially made for this display. An import function allows additionally to use Windows fonts. With the

FontEditor it is easy to generate for example Cyrillic, Greek and Arabic fonts. The preview function

shows immediately the size and style in simulation window.

When the testboard EA 9780-3USB is connected to the USB port, you can see the character (or any

predefined text) live on the display !

3 WIRE, 9-BIT SPI-MODE

Falling edge on PIN CS0 (or rising edge on

PIN CS1) is used for chip select and bus cycle

reset. First of all the CD-Bit is transferred to

select whether data (H) or command (L) is

followed up within the next 8 bit (MSB first)

The clock-pulse rate of the CLK line can be up

to 8 MHz, depending on power supply and

wiring.

DATA TRANSFER

The EA DOGXL240-7 supports three serial modes. The data transfer of the

two SPI-Modes is unidirectional, that means data can only be written, not

read back. Compared to other displays, a busy query is not necessary. The

clock-pulse rate of the CLK line can be up to 8MHz, depending on the supply

voltage and interface mode.

More detailed information on timing can be found on page 64 to 66 of the data sheet of the UC1611s

controller on our website at http://www.lcd-module.de/fileadmin/eng/pdf/zubehoer/uc1611s_v1_0.pdf

4 WIRE, 8-BIT SPI-MODE

Falling edge on Pin CS0 (or rising edge on PIN

CS1) is used for chip select and bus cycle reset.

During each write cycle, 8 bits of data, MSB

first, are latched on eight rising CLK edges into

an 8-bit data holder.

If CD=0 (reading at D0), the byte will be

decoded as command. If CD=1, this 8-bit will

be treated as data byte.

The clock-pulse rate of the CLK line can be up

to 8 MHz, depending on power supply and

wiring.

2 WIRE, I2C-MODE

Pin A2 and A3 is used to configure the device address. That means up to 4 displays can use the same

I²C bus.

The I²C mode has a bidirectional data transfer, i.e. data can be read back from the display’s ram.

The clock-pulse rate of the CLK line can be up to 1.7 MHz, depending on power supply and wiring.

Please be informed, that the pins SDA+SCK contain an

internal resistance of 600 to 1000 Ohm, or even more

(Important, because of the LO-level while reading data and

the ACK-Bit).

Important: After the commands to set page or column

adress you always have to read a dummy byte.

USB-TEST BOARD EA 9780-3USB

For easy startup, an USB test board is available that can be connected

to a PC. It comes with an USB cable and a Windows software. This

allows text and images (BMP) to be displayed directly on the plugged-

in display. You will find more information on the test board in the

EA 9780-3USB’s data sheet.

SIMULATION WITH WINDOWS

A simulator window also displays the contents of the display. The

software can simulate all the displays and colors even without the

hardware. You can download the software for free from our website.

TOUCH PANEL EA TOUCH240-3 (OPTIONAL)

An analog touch panel is available as an accessory. It has a self-

adhesive material on its rear side that makes it simply to stuck onto

the display. The connection is made by means of a 4-pin flexible

cable for a ZIF connector

(e.g. EA WF100-04S) with a

grid of 1.0 mm. Bending

radius is defined with min.

5mm. For optimum

readability we

recommend

that you use a

backlight with

the display.

Interfacing to a µC can be either done via external

touch panel controller or directly with a µC that is

featured with analogue inputs.

How to work with it ? The touch panel is similar to

a potentiometer: connecting a voltage of e.g. 3.3V

to the pins

Top-Bottom

makes it possible to read

out a voltage on pin

Left

Right

which is linear

to the Y-coordinate of the pressed point. The X-

coordinate will result when the voltage will be

supplied to

Left-Right

and measurement is done

Bottom

The pinout of the connecting cable is shown in

the drawing.

12:00 VIEW ANGLE, TOP VIEW

If the display is read mostly from above (on the front

of a laboratory power supply unit, for example), the

preferred angle of viewing can be set to 12 o’clock.

This rotaties the display by 180°. A slightly different

initialization setup is required for this.

MOUNTING / ASSEMBLING

First, clip the display and backlight modules together by gently pushing the display pins through the

corresponding holes on the backlight module. Then insert the entire module into the socket, or into

the soldering holes on the pcb. The backlight pins (6 pins at the bottom) must be soldered on the top

side as well to ensure good contact between the modules.

Important:

- The display and the backlight do have in summary 3 protective films. There are some on the top

and the bottom of the display and also one on the backlight. These must be removed.

- LC displays are generally not suited for wave or reflow soldering. Temperatures of over 80°C can

cause lasting damage.

- Make sure that either display nor backlight will never come into contact with any kind of liquid like

Fluxer, Cleaner, Water.

ATTENTION

handling precautions!
