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 a Raspberry Pi® hardware board. Device driver blocks provide easy access to hardware board features, such as communication protocols or hardware libraries, that are not included in the default Simulink Support Package for Raspberry Pi Hardware.
You can develop a device driver block from a template System object™ and then share the completed blocks with other users.
