Embedded Coder’s Hardware Support Package for Wind River VxWorks RTOS is discontinued from R2017b and beyond. However, you can still generate ANSI/ISO C/C++ code using Embedded Coder and thus supports RTOS (Real-Time Operating System) that support C/C++ compilers.
If portable ANSI/ISO C/C++ that can be called by any scheduler is not sufficient, Embedded Coder has a variety of options and features that end users can leverage to generate target specific code for their particular RTOS environment.
