Bridgetek helps simplify human machine interface (HMI) development, by broadening the scope of the toolchain that accompanies its Embedded Video Engine (EVE) product portfolio. Several extra elements have now been added, plus major upgrades and augmentations made to the existing tools.

A core aspect of this toolchain is the EVE Asset Builder (EAB), a conversion utility that makes HMI construction much more straightforward and saves time, as 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, this tool has video conversion functionality, as well as an animation generator (for use with the latest generation of higher-end BT81X series EVE devices).

Enhancements have also been made to the low-level EVE Screen Editor (ESE) element of the toolchain - which is intended to offer users a simple drag-and-drop environment in which they can start experimenting with EVE-based HMI projects. The EVE Screen Designer (ESD) tool handles the entire workflow (with overall HMI design, widget design, simulation and export all encompassed), with support for the functional aspects offered by Bridgetek’s BT81X devices.

Features include adaptive scalable texture compression (ASTC), as well as Unicode features. Numerous BT81X specific example projects can be readily utilized - 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. Among these are Arc Slider, Circular Slider, Ring and Partial Ring.
