Displays Continue to Reign Supreme Evaluation Kit Promotes Familiarization with Display Trend
There are hardly any devices left that do not feature a display for operating, control, or programming purposes. The EA eDIPTFT57-A intelligent display from Electronic Assembly is the ideal candidate for implementing an interactive control in mechanical engineering or industrial electronics applications, as well as in all other conceivable scenarios, due to its performance characteristics and elegant, straightforward development support. The high-contrast screen, 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.
SpecThe evaluation board features a USB connection for communicating with the PC. Interface daughter boards for RS-232, I²C, and SPI do come with the shipment to communicate with the host computer of the target application.
An external power supply is not required for smaller displays. An array of LEDs provides information about data traffic and the status of the digital outputs of the display. Two potentiometers and eight buttons are fitted to the evaluation board to emulate sensors, switches, or relay contacts in the target application. The installation DVD encompasses an abundance of material, including documentation on the different displays, the development software, and a variety of sample macros and layout templates. The source text editor for creating customized macros integrates additional programs (a compiler, a terminal program, a bitmap editor, and an editor for designing virtual measuring instruments) via icons. The touchscreen, which has a buzzer to confirm inputs, can also group controls on the display to realize a high-quality user interface.
