Developing VIs for C Code Generation (C Generator)

Complete the following steps to develop a VI for C code generation.

1. Create a new LabVIEW project in the Project Explorer window.
2. Create the VI you want to export for C code generation under the My Computer target in the project. The exported VI must be under the My Computer target in order to generate C code for the VI.

   Note  You can export only one VI per build specification for C code generation.

3. As you develop the VI, account for differences in VIs developed to run as LabVIEW applications and VIs you develop for C code generation. Exported VIs and all VIs in their hierarchies support the following block diagram objects differently from VIs running as LabVIEW applications:
   • Application Control VIs and functions
   • Express VIs
   • Data type support
   • Fixed-point data types
   • Libraries and executables
   • Memory Control functions
   • Numeric functions
   • Signal Processing VIs
   • String functions
   • Structures
   • Timing VIs and functions
   • Unsupported VIs and functions
   • Support for MathScript RT Module functions

   Note  You cannot debug an exported VI in LabVIEW. Debug the generated C code in an external IDE.

4. On the Source Files page of the C Code Generation Properties dialog box, specify the VI you developed in the Exported VI listbox.

After you develop the VI for C code generation, you must customize the platform definition file, define C code generation options, and configure the exported function prototype.
