PINOUT

The EA DOGM240-6, a 240x64 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 the

EA DOGM- Series. The

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.

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 9780-4USB is connected to the USB port, you can see the character (or any
predefined text) live on the display !

4 DIFFERENT BACKLIGHTS

Four different backlight types are available to match equipments design as much as possible. Incl. 2­and 3-color green/red. The most effective and brightest one is the white one EA LED94X40-W.

EA LED94X49-W (white) - the super bright one
With the white backlight, there are 3 separate LED
paths containig 2 LEDs in series each. We are using
high-quality LEDs from NICHIA. To operate the backlight

with longest life time, we recommend a
current source (e.g. CAT4238TD). Life time
typ. 80,000 hours.

or in
series to

APPLICATION EXAMPLE LED DRIVER FOR 3.3V

Based on white backlight EA LED94x40-W with the help of current source CAT4238.

Important: Do never connect
the backlight LEDs directly to
a 5 V/3.3 V supply as this may
immediately destroy the LEDs.
Please note that derating
applies at temperatures
exceeding +25°C.

USB-TEST BOARD EA 9780-4USB

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 plugged­in display. You will find more information on the test board in the
EA 9780-4USB’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:

https://www.lcd-module.de/fileadmin/downloads/startdog_v45.zip

SOCKET EA FL-20P

With the help of the single-row female connector
stripe EA FL20-P the mounting of the display is
detachable. In addition the overall height can
be adjusted.
2 pieces are required each display!

DOGM240-6 GRAPHIC

DATA TRANSFER

The EA DOGM240-6 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.

Serial Modes

BM0 D13 Description

0 0 4-wire, 8-Bit SPI

1 0 3-wire, 9-Bit SPI
1 1 2-wire, I2C

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.

DOGM240-6 GRAPHIC

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.

TOUCH PANEL EA TOUCH240-4 (OPTIONAL)

An analog touch panel is available as an accessory. It has a self­adhesive material on its rear surface and is simply 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 processor can be either done by an external touch
panel controller or with a controller that is featured with analogue
inputs. The touch panel is similar to a potentiometer: connecting a
voltage of e.g. 3.3V to the pins
makes it possible to read out a voltage on pin

which is li- near to the Y-coordinate of
the pressed point. The X-coordinate will result
when the voltage will be supplied to

12:00 VIEW ANGLE, TOP VIEW

If the display is read mostly from above (on the
front of a laboratory power supply unit e.g.), the
preferred angle of viewing can be set to 12 o’clock.
This rotaties the display by 180°. A slightly different

12:00 o’clock (Top View)6:00 o’clock (Bottom View)

initialization setup is required for this.

ATTENTION

handling precautions!

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.
