Device Driver Blocks
A device driver block is a specialized form of the MATLAB System block that generates custom C/C++ device driver code when deployed to an Arduino® hardware board. Device driver blocks provide users easy access to hardware board features, such as communication protocols or hardware libraries, not available in the Simulink Support Package for Arduino Hardware.
You can develop a device driver block from a template System object™ and then share the completed blocks with other users.
