Create Custom IO Device Blocks

IO Device Builder App

Use IO Device Builder app to quickly create a System block for custom or third-party source files (C/C++) using third-party source files. Launch the IO Device Builder app and a series of screens then leads you through the process of creating a System Object, which is then used to create a Simulink block. Choose this option when you need a rapid solution, enabling you to swiftly create a Simulink block.

Programmatically Create IO Device Block

Use Device Driver block, a specialized form of the MATLAB System block to programmatically create IO blocks with easy access to hardware board features, such as communication protocols or hardware libraries, not available in the Simulink Support Package for Arduino Hardware. Choose this option when you need more extensive capabilities for your custom IO blocks. However, this option might require more time to create the block.
