SOFT DB SimulinkToSR Converter Quick User Guide Page 1 sur 5 The MathWorks p Simulink to Signal Ranger Simulink Converter Quick User Guide As its name indicates the SimulinkKToSR program links Matlab Simulink files to the Signal Ranger DSP board Doing so DSP programming is now possible for almost everyone First the user needs Matlab Real Time Workshop to transform the Simulink model into C language Next the generated files are sent through the SimulinkKToSR Converter It then generates a out file that can be directly implemented on the Signal Ranger board The required process time ranges from a few seconds to one minute depending on the system complexity After these steps have been completed the SimulinkToSR interface allows you to communicate with the DSP board It is then possible to dynamically modify the parameters of your Simulink system and see its effect right away SimulinkToSR Converter Demonstration Video Download the demo video that explains how to use the SimulinkKTOoSR Converter software and shows the main functionalities ary lt a Simulink Demo Video Implementation Procedure The following text describes the quick steps to implement a Simulink design on Signal Ranger DSP However the reading of the user manual is recommended for better comprehension Configure your Simulink file Design your system under Simulink Predefine Simulink variables in MatLab workspace Export variables Build m
