(EFL) Enlightenment Foundation Libraries on SBC-SAMA5D36

Products for consumer market, industrial control systems and other embedded devices often require a touch screen display to offer both, visual feedback to the user, as well as an input method to interact with the system. In order to achieve a nicely designed and responsive user interface, developers can either write their own graphical library providing widgets like drop-down menus and buttons or take ready to use libraries like Qt or EFL.
Now which library should one select, especially in terms of limited hardware resources on embedded systems but also with a look forward to the look&feel as well as the usability on a touch screen? Besides, hardware restrictions, like the used CPU and its computing power, available RAM-size, free space in ROM, availability of a GPU with 2D/3D hardware accelerated graphics and the used operating system, should be taken into consideration. emWin for example, runs on bare-metal systems either with or without a RTOS whereas Qt or EFL need at least a running Linux (but not said that it is impossible to run them on bare-metal). Other decision affecting parameters are the availability of the library as open- or closed-source, as well as the costs for non-commercial and commercial products.

In the following article we will take a brief look at the Enlightenment Foundation Libraries (EFL) of a small Cortex-A5 based single board computer from emtrion running a Debian Jessie based Linux: the SBC-SAMA5D36.
