SGE2 with Vector Graphics released

Kleinhenz ELEKTRONIK now offers its SGE2 framework for build Web enabled device, with vector graphics (SVG and Canvas). It is simple to combine text based forms and graphics on a single web page. These graphics are place by drag and drop in the document.


New Homepage

After a server crash we're online again with new content and a new design.


Kleinhenz ELEKTRONIK @ Weka IoT on 22th October 2015 in Munich

Invited by Weka Verlag, Mr. Kleinhenz will presented a speach about IoT Net (LPWAN).


What is SGE2?

SeeGeeEye (SGE2, the second version) is a programming framework for building web front ends for embedded devices. It includes all the tools for producing a sophisticated GUI with different requirements, designing the pages, creating menus, assigning a template (CSS style sheet) to it, and interfacing with the hardware or another application. On the embedded system, there is also web server integrated.

Presently SeeGeeEye runs under Linux 2.4 and 2.6 on ARM, X86, PowerPC, MIPS processors. It is prepared to be ported to real embedded systems without a standard operating system. A demo version is also available for Windows.

SGE2 uses standards

SGE2 relies on standards. It does not need any proprietary extension or plug-in like Flash, Java, or Silverlight. A list of standards and protocols used by SGE2:


With this it can easily be integrated in an existing environment. Any modern browser can display the HTML pages and interact with SGE2.

SGE2 is open

With its plug-in system, new interfaces or protocols can be added. For process control, a OPC server can integrated.

SGE2 is easy to use

The development of a embedded web application is usually very time consuming. It is necessary to merge many libraries (like for TCP/IP, UDP, SNMP, SMTP, ..) and programs (web server, CGI extensions, SNMP agents, SQL data base, ...) together and try to get them working. This may take a long, long time. After that, the HTML pages, the JavaScript, the CSS can be done. And any change during the design is also not easy, because all the component maybe influenced by that.

SGE2 comes with a revolutionary concept: SGE2 supplies a preconfigured, ready to use application, and tools to adopt it the needs of the new design.

So it is very easy to get good results in a very short time.

SGE2 is fast

SGE2 is fast in two ways:
  1. Design phase can be heavily reduce due to its easy way of working. The first results can be achieved within a few hours of implementation.
  2. The run time system is fast. It is completely written in C and C++. No interpretation language is used like php, JAVA, or ruby. Additionally the integrated web server is optimized for SGE2 requirements.

SGE2 is modular

A very important feature of SGE2 is, that it speeds up the development process:
Front end design (GUI) and application development can be separated. All experts can work in parallel, independent and very efficient.

The GUI specialist will take care for the presentation and usability, while the software engineer programs the application. The hardware developer can make his design in parallel, because SGE2 can work without any hardware.

Many standard feature are available as modules( like event handling, logging, scheduling, communications, graphics, ... and many more) for SGE2, and need not be programmed. They are fully tested, optimized for SGE2, and can integrated with a few mouse clicks. Ask for the latest list of available modules.

SGE2 is flexible

SGE2 can be used in many areas.

SGE2 can be ported to many operating systems and platforms, and can also be used in real embedded system without an OS.

SGE2 can be used for small ( up to a few hundred data points) and very large systems (more than 10 000 data points).

It is even possible to split the functionality over several computers. This makes SGE2 the best choice for small AND large systems.

SGE2 is small

designed to be used in embedded system with restricted resources like
computing power
power consumption
memory footprint
A typically runtime system alone (without JavaScript, HTML pages, CSS files, bitmaps, and user application) needs only 100 kB.

What applications can be build with SGE2?

SGE2 is designed to build any web based embedded systems.

It can be used for computer peripherals, gateways, home automation and appliances, industrial automation, facility management, energy management, traffic control, measurement systems, metering devices

The range of application can also be described by remote control, maintenance, inventory, concentrator, VOIP telephones, gateways, protocol converter, measurement instruments.

All the apps have in common, that they are accessed over a network with a modern web browser.

How to design the user interface(GUI) with SGE2?

The designers are the major tools and an important part of SGE2. To fulfil the different requirement of the to designed application, so there are three different editors available to build the front end (GUI) of SGE2.

  1. SGE2 Form Generator (for text based applications)

    With a few clicks in the SGE2 Form generator a new HTML page is build. Even complex forms can be done without any HTML knowledge. It support standard HTML elements, like text input, text area, drop down box, radio buttons, check boxes ... and many predefined types like select boxes for date or country. For each line a label, a description, and a help button can be assigned. Tables with different options, real time graphs and diagrams (in pseudo graphic; for real graphics see below) provide a good overview for the data.

    The menu generator arranges the designed pages in the desired order and links all pages together. There are vertical and horizontal menus possible.

    Predefined and user changeable CSS style sheets are used to give it an individual appearance.

  2. SGE2 designer

    It also knows the standard HTML elements, but they can be located anywhere on the document. Registers are supported, to have compact design.

    JavaScript is used to make all this happen. It is mainly used for smaller projects.

  3. SGE2 graphical designer (coming soon)

    The full graphical designer is the right tool for all process visualisation. Through the use of SVG, it is open to integrate graphic data from other programs.

    All designers are web based and can be used with all operating systems. Additionally SGE2 designer is a JAVA app and can run stand alone on all operating systems with JAVA support (Windows XP, Vista, 7; MacOS, Linux).

    The output (HTML pages and SVG files) can even be combined within a single project. This is achieved by the use of the same communication protocol with the web server.

SGE2 Alarm System

The SGE2 framework has a very powerful alarm system. Any dangerous status can be reported to the operator(s). It sends multiple messages over several communication channel like SMNP trap, syslog message, email, and SMS. If the alarm condition goes away, another messages can be sent. An internal log file keeps track of alarms.

SGE2 Event and Schedule System

It is used for automatically repeated procedures, on a fixed time, or periodically from seconds to hours, or on daily, weekly, monthly, or yearly basis. Each main event may have a number of exceptions, so that for example the maintenance will not be done on Sundays or during holidays.

Each time event can be combine with the alarm system.
