HMI Interface to Embedded Electronics: 5.7 Color Display – Including with Touchscreen Capability

The high-contrast screen, for example, which measures 5.7 in the diagonal and has LED background illumination, offers a crisp, colorful resolution of 640 x 480 pixels. Its most important feature, however, is the built-in intelligence that greatly facilitates developers who want to integrate the display modules in their application.
The device also provides acoustic feedback in addition to outputting information on screen, thanks to the integrated sound module that can play start-up tones, confirm keyboard inputs, and issue warning messages. A virtual on-screen keyboard rounds off the list of convenience features of the EA eDIPTFT57-A.

The intelligence of the display unit makes it easy to program interactive user interfaces. In conjunction with the optional touch panel, developers can create a virtual keyboard in just a few steps. Keyboard inputs are processed directly on the display in an edit box. This allows operators to use standard text formatting commands without placing a large workload on the programmer.

A high-level language macro programming facility is an important aspect of the integrated intelligence of this display and represents an elegant way of developing applications. Lines, bar charts, and areas can be defined using a single command and displayed on screen. Developers can also quickly and conveniently define and activate the appearance, size, arrangement, and function of keys and buttons. This dramatically boosts the productivity of application development and slashes the time that elapses from the moment an order is placed to the day the project is completed.

The EA eDIPTFT57-A offers many additional features that facilitate programming so that complex contents can also be displayed with ease. Application developers can save fonts, images, animations, and function macros in an integrated flash memory. Eight fonts are supplied and can be scaled and varied as required. TrueType fonts, which are commonplace in the PC world, are easily imported.

A programming library contains a variety of predefined, virtual rotary and pointer instruments that can be used to output analog readings, for example. Macro pages and string tables help to design content in multiple languages – an important feature for companies looking to adapt their products for foreign markets.

An evaluation kit is the perfect way to familiarize yourself with the EA eDIPTFT57-A
