Target Language Compiler

Getting Started

1. Copy the entire directory tlctutorial/mygain to your working directory, so that you can use the files provided.

Note    You must use or create a working directory outside of matlabroot/ for models you make. Simulink complains and refuses to build models in its own source directories

2. Open the model file simple_sin.mdl, which consists of three blocks.

3. Choose the Target configuration category from the Real-Time Workshop tab of the Simulation parameters dialog box. Select Generate code only.
4. Generate code for the model and inspect the MdlOutputs() section of output file simple_sin.c (in your build directory).

• /* Compute block outputs */
  void MdlOutputs(int_T tid)
  {
    /* local block i/o variables */
    real_T rtb_Sin;
  
    /* This is a single rate system */
    (void)tid;
  
    /* Sin: '<Root>/Sin' */
    rtb_Sin = rtP.Sin_Amp *
      sin(rtP.Sin_Freq * ssGetT(rtS)+rtP.Sin_Phase)+rtP.Sin_Bias;
  
    /* Outport: '<Root>/Out' incorporates:
     *   Gain: '<Root>/Gain'
     *
     * Regarding '<Root>/Gain':
     *   Gain value: rtP.Gain_Gain
     */
    rtY.Out = (rtP.Gain_Gain * rtb_Sin);
  }
  

Note that:

• Comments are generated, because the Generate comments Real-Time Workshop code generation option is on by default.
• No loops are generated (because the input and output signals are scalar).
