Source Code Generation

Generate and verify source code modules for function deployment and integration

Learn how to initiate source code generation and learn about the files and folders that the code generator produces. To organize large projects, use the code generation project template. Projects help you find required files, manage and share files and settings, interact with source control, generate controller code, and run test harness simulations.

You can start with Generate Code by Using the Quick Start Tool.

Apps

Embedded Coder

Generate readable, compact, and fast C and C++ code for embedded processors used in mass production

Functions
