Simulation for EA DOG Displays, Character and Graphic

Simulation for Windows

A great help for orientation in the "colour-jungle" the DOG-Simulator is an excellent tool: all displays (text and graphic) as well as all different backlight options can be simulated on screen. Free of charge!

USB test board for EA DOG Displays, Text and Graphic

The test board EA 9780-4USB

The test board EA 9780-4USB adapt all display with its multiple sockets. Even all modules with and without backlight are supported.

The displays do show the individual text and pictures from simulator immediately - without any development action. In addition to that the backlight can be switched on and off. This makes possible a realistic test operation. Without the need to write software or to create any hardware adaptor. Immediately and as easy as ABC.

Arduino meets DOG

Arduino meets DOG

That's the easy way driving a display: the Arduino concept provides a very good base for such.

Some displays in EA DOG series we do support with all things to bring the display into operation with an Arduino Uno easyly: Sketches, Libraries, Documentation, EAGLE *.brd  and *.sch Files.

We also do provide non-assembled pcb boards.

Here you do find a table as an overview.

EA DOGS102W-6

Character Set and Fonteditor

With the ordering code EA USBSTICK-FONT a memory stick comes with various character sets, especially made for displays from DOG series.
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 9780-2USB is connected to the USB port, you can see the character (or any predefined text) live on the display which is plugged-in!

The export function generates a C- and Basic source code as an include file to your software.
Also included is a converter software for *.bmp files.
