Abstract

The Dynamic Systems Library (DSLib) is a newly developed interface tool for use between block-diagram modelling and realtime programing. DSLib is a set of C++ classes representing components of block-diagram modelling: blocks (functions, integrators, summing points…), inputs, outputs, schedulers, etc. Such classes can be used in standard C++ code to define simply a dynamic system from a block-diagram approach. Once the system is properly defined, DSlib classes generate the implementation of the dynamic system for a specific realtime operating system (DSLib and RTAI, at the moment). DSLib has the following advantages with respect to ease of implementation: – It is an easy tool for users familiar with dynamic systems modelling. There is a direct equivalence between a block diagram and its DSLib definition. – It encapsulates the target operating system, so standard C and C++ is the only required programming knowledge. DSLib will generate the specific functions for realtime threads definition and interaction, memory managing, etc. For interaction of the dynamic system with the external world, DSLib also provides classes to easily define realtime fifos, shared memory, and even hardware inputs and outputs by using the Comedi library. From the point of view of the software developer, DSLib can be the kernel of any dynamic system modelling application. For example, a Matlab-like application can be obtained by just adding a user interface. For more info, please visit http://dslib.sourceforge.net/
