Modelica_DeviceDrivers

Free library for interfacing hardware drivers to Modelica models. There is support for joysticks, keyboards, UDP, TCP/IP, LCM, MQTT, shared memory, AD/DA converters, serial port and other devices.

Library description

The Modelica_DeviceDrivers (MDD) library is an open source Modelica package that interfaces hardware drivers to Modelica models. An overview of the library is provided in

Bernhard Thiele, Thomas Beutlich, Volker Waurich, Martin Sjölund, and Tobias Bellmann, Towards a Standard-Conform, Platform-Generic and Feature-Rich Modelica Device Drivers Library. In Jiří Kofránek and Francesco Casella, editors, 12th Int. Modelica Conference, Prague, Czech Republic, May 2017. Download

The library unifies previous developments concerning device driver support in Modelica, see Interactive Simulations and advanced Visualization with Modelica and Modelica for Embedded Systems (Modelica'2009 conference). The functionality covered by this library has been used internally at DLR for several years, such as for Driver-in-the-Loop simulation and for the DLR Robot Motion Simulator. The previously fragmented functionality was streamlined, improved, and extended to a coherent cross-platform library.

Main features:

All device drivers are made available via external Modelica functions. Furthermore, high level interfaces on these functions are provided via Modelica blocks. The first interface uses Modelica 3.2 functionality only (when-clauses and sample-operator). The second interface uses the synchronous language elements introduced in Modelica 3.3 and is based on clocks.

Development and contribution

The master branch of the Modelica_DeviceDrivers library should work out-of-the-box when loading the library into a supporting Modelica tool. The branch contains the necessary external C libraries as pre-build binaries below folder Modelica_DeviceDrivers/Resources/Library.

If you need to build the external C libraries from the sources, clone the repository with

git clone --recursive https://github.com/modelica-3rdparty/Modelica_DeviceDrivers.git
git submodule update --init --recursive

and see Modelica_DeviceDrivers/Resources/README.md.
