Device Driver Blocks
R2026bCreate device driver block to access specific features of hardware board
A device driver block is a specialized MATLAB System (Simulink) block that generates custom C/C++ code when you deploy a model to an AMD® SoC device. It enables access to board-level features, such as communication protocols and hardware libraries, which are not available in SoC Blockset™ Support Package for AMD FPGA and SoC Devices.
Create a device driver block by using a template System object™ and share the completed block with others.
