Bridgetek expands its HMI EVE portfolio

The toolchain available from Bridgetek for its Embedded Video Engine (EVE) product portfolio has undergone major upgrades and augmentations to the existing tools as well as the addition of new elements.

One of these new elements is the EVE Asset Builder (EAB). The conversion utility makes human machine interface (HMI) construction more straightforward “and saves considerable time”, says Bridgetek, as it means that users do not need to remember the various command line options for each different constituent utility in their design. As well as covering conversion of image, audio and font files, the intuitive tool has video conversion functionality and an animation generator (for use with the latest generation of higher-end BT81X series EVE devices).

Enhancements to the low-level EVE Screen Editor (ESE) offer users a drag-and-drop environment in which they can start experimenting with EVE-based HMI projects. Usage examples have been added, including those relating to the touch tracking function, use of high-quality Paletted8 bitmaps and bar graphs.

The EVE Screen Designer (ESD) tool, which handles the entire workflow (with overall HMI design, widget design, simulation and export all encompassed), can now support all the functional aspects offered by Bridgetek’s BT81X devices, such as the use of larger, higher resolution images thanks to adaptive scalable texture compression (ASTC) and Unicode features. There are BT81X-specific example projects that can be used, including one focused on designing HMIs for electric vehicle charging points. Additional widgets have been accommodated which complement the existing dial, clock and slider options, including arc slider, circular slider, ring and partial ring.

Users can get an accurate evaluation of how a BT816 design will be rendered on an actual display rather than just seeing an approximation on a PC screen.

All of the elements in the updated EVE toolchain can be downloaded for free from the Bridgetek website
