Developing Userfriendly Applications with Simulink Target for RTLinux
Klaus Oppermann, Daniel Schleicher, Peter Reiter, Bernhard G. Zagar
These days most applications are developed via rapid prototyping systems. Control and measurement applications both need easy to use user interfaces, that can quickly be built during the construction process of the application. Usually such prototyping systems are relatively expensive in both hardware and licensing fees (e. g. LabView, dSPACE).
In the proposed paper we show that rapid prototyping and user interface creation is also possible on the basis of a low{cost open source RTLinux system by extending with several tools the "Simulink Target for Real-Time Linux" (STRTL), the implementation of the DSP-blocks in STRTL, the Comedi STRTL-interface and the strtl procctrl driver for the webpage-interface.
The paper is organized as follows:
First a brief introduction into RTLinux and STRTL is given. Subsequently the main components of the system are described in detail. These contain the Comedi STRTL{interface to use data acquisition cards, the strtl procctrl driver to handle the model{webserver communication, the strtlcrontab which enables the execution of root commands via a webpage and a guide to include simulink blocks which are not supported by STRTL yet.
A small demonstration application shows how the described tools collaborate. We close our paper with some concluding remarks and the reference to our website where these extensions can be downloaded for free.
