Software for designing HMIs

29 April 2015 Design Automation

Bringing more comprehensive support to its Embedded Video Engine (EVE) product offering, FTDI Chip is introducing freely downloadable EVE Screen Designer. Suitable for use with Windows operating systems (version 7 and above), this software enables the creation of advanced human machine interfaces (HMI) via EVE’s innovative object-oriented approach, without any understanding of EVE display lists.

Using this software tool on a purely visual level, highly intuitive HMIs can be derived via primitive objects such as circles and squares, as well as an array of more complex built-in widgets (including buttons, dials, clocks, gauges, sliders, scroll bars, text boxes, etc.) which are made up of multiple objects.

Designers can specify an EVE hardware platform and set the resolution required; then by choosing and subsequently placing objects on the screen they can rapidly begin constructing an HMI. Objects can be moved from one place to another using the cut and paste function, and can be pushed back or pulled forward. An adjustable grid aids screen positioning and alignment.

Provision is given for editing widget properties (colours, sizes, text fonts, etc.), with objects being locked/unlocked as needed. In addition it is possible to zoom in/out on objects and group them together. User interface designers can consult the display list when necessary or make use of the step-by-step display list debug function. Finally they can export the completed screen to the display list via text file.
