Device Driver Blocks

Create a device driver block to access specific features of your hardware board

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 the other users.
