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