You can open the ARM Cortex-based VEX Microcontroller block library in two ways.
The MATLAB® Command Window. This approach is quick, but does not display the other Simulink® block libraries that are available.
The Simulink Library Browser. This approach is slower, but displays all of the Simulink block libraries that are available.
In the Command Window, enter
Double click on the Utilities block to open up the Utilities library that contains competition-specific blocks.
Alternatively, from the Simulink Library Browser, locate and select Simulink Coder™ Support Package for ARM® Cortex-based VEX® Microcontroller.
Rapid Accelerator simulation is not supported by Simulink Coder Support Package for ARM Cortex-based VEX Microcontroller.
