TOUCH PANEL EA TOUCH160-1 (OPTIONAL)

An analogue touch panel is available as an accessory. It has a self-adhesive glue 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 pitch of 1.0 mm. Bending radius is defined with min. 5mm.

For optimum readability we recommend that you use a display with backlight.

Interfacing to a processor can be either done by

an external touch panel controller or with a

controller that is featured with analogue input

lines. 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 X-coordinate 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.

USB-TEST BOARD EA 9780-2USB

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 displayed directly

on the plugged-in display. You will find more information on the

test board in the EA 9780-2USB 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. It runs also without the USB test board:

CHARACTER SETS AND FONT EDITOR (ACCESSORY)

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

An import function additionally allows to use Windows fonts. With the FontEditor it is easy to gene-

rate for example Cyrillic, Greek and Arabic fonts.

The Preview function cooperates perfect with the testboard EA 9780-2USB on USB port.
