Tutorial for Generating C Code from a Control Algorithm for an Embedded System

This guided tutorial uses a series of examples to show the workflow of generating code from a control algorithm for an embedded system. In each example, you learn how to perform a specific aspect of code generation or integration. The examples are based on a shared model. Each example has a unique version of that model and corresponding data set so that you can use the examples independently. You do not have to run the examples in a specific order. When you transition between examples, you save the current model so that each example captures your modifications to the model and model data.

To recover a model in its original state, delete your local copy of the model and model data. The model data is saved as PCG_Demo_#_data.mat.

1. Prepare a Control Algorithm Model for C Code Generation

2. Configure Data Interface in the Generated Code

3. Partition Functions in Generated Code

4. Call External C Code from Model and Generated Code

5. Build Integrated Code Outside the Simulink Environment

6. Test Generated Code

7. Evaluate Performance of the Generated Code

8. Install and Use Cygwin and Eclipse

Third-Party Software

Some of the examples use the Eclipse™ IDE and the Cygwin™/gcc compiler. Instructions to install and use Eclipse™ and Cygwin™/gcc are available in Install and Use Cygwin and Eclipse.
