Renesas Synergy is a complete and qualified platform with fully integrated software, a scalable family of microcontrollers, and unified development tools to speed embedded system developers’ time to market as they innovate new products.

At the heart of the Synergy Platform is the Synergy Software Package (SSP), which is qualified, supported, warranted, and maintained by Renesas. The SSP consists of a proven real-time operating system (RTOS), stacks for USB and Ethernet, file systems, a graphic users interface (GUI), and more – all accessible through a robust Application Programming Interface (API) to free designers from struggling with lower-level details.

Based on the very popular and customisable Eclipse IDE, the Synergy IDE is very simple to understand and to get the graps of it.

In the past few months emtrion has broaden its knowledge base towards the open source virtualization platform Jailhouse [1]. The eventual goal is to provide customers a virtualization solution that is real-time capable, lightweight, secure, certifiable and operable on emtrion hardware. The main advantage to customers will be the reduction of costs through the combination of multiple hardware units into one single unit that handles multiple tasks.

Introduction

In general most of emtrion’s hardware comes with interfaces like Ethernet, RS232, CAN, GPIOs, I2C, SPI. In addition, the used CPU modules are supported by a powerful microprocessor.

Such preconditions are predestinated in controlling industrial systems. In many cases, programming in this environment is based on the widely-known standard IEC 61131-3.

If you consider these items, the question to ask is, are there any reason why you are not using emtrion's hardware as PLC. Not really. On the one hand it's dependent on the use case and its requirements such as real-time, certification etc. and the other hand on the effort needed to transform it to a PLC.

Transforming is an independent part of the use case and means to make an emtrion hardware a PLC. The transformation is limited by adding a piece of software, the so called RTS (runtime system) to the RFS (root filesystem).

The RTS we used, it is possible to make a PLC in less than one work day.

Following the proceeding steps are described.

Introduction

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 write their own graphical library providing widgets like drop-down menus, list-views, check-boxes or simple buttons. However, this can be a very tedious and error-prone task. It is best to use one of the available graphic libraries like Qt[1], Cairo[2], EFL[3] or also emWin[4], not to forget to mention nCurses for console-style block-oriented graphics.

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 [5].

Android has established itself as a dominant mobile operation system for consumers in recent years. It is indispensable in the field of applications such as smart phones, cameras, tablets, game consoles and much more. The Android-Software-Development- Kit (SDK) is extensively equipped and offers substantial possibilities for programming complex applications. Based on a complete Linux-kernel, Android is operated by a touch-based user interface. In fact, these are ideal conditions for the development of appealing and intuitive HMI applications in an industrial environment. However, especially in industry, there are further boundary conditions to be considered before Android can be used.
