It com- bines the high computing performance of a TI TMS320C31 floating- point DSP with a set of I/O modules frequently required in control systems. It is therefore ideally suited to cost-sensitive applications that have a limited number of inputs and outputs but still require fast com- putation. Typical application fields are drives, automotives, and robot- ics control, but customers from many other domains can also benefit from this powerful single-board solution. Programming the DS1102 Board … … is easy with Simulink and dSPACE’s Real-Time Interface. You can initialize and configure all on-board I/O modules graphically within the Simulink environment. Code generation, compiling, and downloading Real-Time Interface provides is reduced to a single mouse click. But even without Real-Time Inter- Simulink blocks for a convenient face, putting the DS1102 board into operation is an easy task with the configuration of A/D, D/A, C software environment included, which is complemented by a digital I/O lines, incremental debugger, compiler, and loader software. Any application running on encoder interface, and PWM the DS1102 can be fully controlled by the dSPACE experiment soft- generation. The PWM dialog ware, including instrument panels and data acquisition tools in allows you to enter the desired ControlDesk, and various tools for test automation.
