Development tool realises HMI without coding effort
To support the FT81x embedded video engine (EVE) graphic controllers, Bridgetek has released Version 3 of EVE Screen Designer. ESD3.x IDE (integrated development environment) facilitates EVE-based human machine interface (HMI) construction.
The intuitive package can create visual effects and graphical content can be edited. It has advanced code generation capabilities (with exported C-based source code, applicable to any hardware associated with the company’s FT90x MCUs), Users rely predominantly on visual programming, though there is provision to use text for editing purposes, they do not need to have an in-depth understanding of EVE display lists.
Using a straightforward drag-and-drop method, widgets (buttons, dials, clocks, gauges, scroll bars) can be taken from a library and placed into the HMI design. Once the design has been completed, ANSI C code is generated in relation to the specified hardware platform.
It is possible to simulate the whole design on the ESD3.0 IDE, before compiling and downloading the generated source code. The logic node editor function gives users visibility of how different elements of the design interact with one another, so they can see what effect changing a particular element will have on the other elements that are connected to it. This can be used to maximise the control structure to allow the coding up of a specific response to a button press, for example.
The ESD3.0 IDE works with the Windows OS 7, 8 and 10.
