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. i 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.

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.

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 ! Printing and typographical errors reserved.

The data transfer of the Serial Modes two SPI-Modes is unidirectional, that means data can only be written, not BM0 D13 Description read back. Compared to other displays, a busy query is not necessary. The 0 0 4-wire, 8-Bit SPI 1 0 3-wire, 9-Bit SPI clock-pulse rate of the CLK line can be up to 8MHz, depending on the supply 1 1 2-wire, I2C 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. 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.

DOGXL240-7 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.

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 9780-3USB’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. http://www.lcd-module.com/produkte/dog.html Printing and typographical errors reserved.

Page 5 DOGXL240-7 GRAPHIC TOUCH PANEL EA TOUCH240-3 (OPTIONAL) Specification An analog touch panel is available as an accessory. It has a selfSpecification min max Unit adhesive material on its rear side that makes it simply to stuck onto Top-Bottom 200 320 Ω the display. The connection is made by means of a 4-pin flexible Left-Right 650 1200 Ω cable for a ZIF connector Voltage 3 12 V (e.g. EA WF100-04S) with a Current 5 25 mA grid of 1.0 mm. Bending Linearity 1,5 % radius is defined with min. Force 90 120 g 5mm. For optimum Contact Bounce 5 10 ms readability we Op. Temperatur -20 +60 °C recommend Stor. Temperatur -20 +70 °C that you use a Transmission 75 85 % backlight with Life Time 100000 Cycles 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 or Right which is linear to the Y-coordinate of the pressed point. The Xcoordinate will result when the voltage will be supplied to Left-Right and measurement is done at Top or Bottom. The pinout of the connecting cable is shown in the drawing. ZIF CONNECTOR EA WF100-04S As an accessory for the touch panel we do provide a ZIF connector (4 pins) with pitch 1.0mm (SMD type). This connector is a „bottom side contact“ type 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. 6:00 o’clock (Bottom View) 12:00 o’clock (Top View) Initialisation example (changes for top view ) Command [21] Set LCD Mapping Control Page 6 CD 0 D7 D6 D5 D4 D3 D2 D1 D0 Hex 1 1 0 0 0 0 0 0 $C0 0 0 0 0 0 1 0 0 $04 Remark Set top view Printing and typographical errors reserved.

Wir übernehmen keine Haftung für Druckfehler und Applikationsbeispiele. DIMENSIONS EA DOGXL240-7 all dimensions are in mm DIMENSIONS EA LED94X67 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.
