Bridgetek’s evaluation hardware uses EVE technology for HMI prototypes
To assist with the initial development and prototyping of human machine interfaces (HMIs) based on Bridgetek’s object-oriented graphic controller ICs, the ME817EV evaluation board features Bridgetek’s BT817 embedded video engine (EVE) device. It allows engineers to experiment with the latest generation of EVE technology and its capabilities. The BT817 supports higher resolutions and large format displays to develop HMIs with broad functionality, offering greater visual clarity and enhanced video playback capabilities.
Measuring 165 x 100mm, the ME817EV has all the necessary attributes for undertaking development work relating to the graphics, audio and touch elements of the HMI. As well as audio amplification and multi-stage audio filtering features, an LED driver can be used to adjust the display backlighting. The evaluation board also includes a touch controller that supports five simultaneous touch points, with 16Mbytes of on-board flash memory resource for storing unicode fonts and image libraries.
The ME817EV can interface with large scale, high resolution display modules. For 1280 x 800 pixel displays it can connect through a 40-pin LVDS interface. A 50-pin RGB interface can be used for 1024 x 600 pixel displays. Capacitive touchscreens may be connected using a six- or 10-pin FPC connector. The board can be powered via a 5.0V supply using the SPI host connector, or via the USB Type-C port.
Fred Dart, founder and CEO of Bridgetek explains the company’s thinking behind this latest introduction: “It is clear that there is a real need for a more streamlined approach to larger format HMI construction. By providing this evaluation platform, we are making the whole project development process a lot quicker and easier for engineers to complete, with much better end results being derived too”.
Founded in 2016, Bridgetek supplies highly advanced ICs and board level products to meet the demands of a constantly evolving global technology landscape. The company’s Embedded Video Engine (EVE) graphic controller ICs each integrate display, audio and touch functionality onto a single chip. The EVE graphic controller ICs are complemented by its highly-differentiated, speed-optimised microcontrollers with augmented connectivity features.
