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++ code when deployed to an AMD^® SoC device. 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 AMD SoC Devices.

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