Device Driver Blocks

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

A device driver block is a specialized MATLAB System block that generates custom C/C++ device driver code when deployed to a BeagleBone^® Black hardware board. Device driver blocks provide easy access to hardware board features, such as communication protocols or hardware libraries, not available in the Embedded Coder Support Package for BeagleBone Black Hardware.

You can develop a device driver block from a template System object™ and then share the completed blocks with other users.
