How can I create sinus wave by using TI C2000 launchpad and simulink?
I am new to microcontrollers. I want to create sinus wave and read it with oscilloscope by using F28379D but I couldn’t manage to do that. Which blocks should I use to do that?

Hello ,
- Open a blank Simulink model, go the configuration parameters (Ctrl+E) > Hardware Implementation > Select the board you are using (i.e. F28379D LaunchPad)
- Drag a DAC block in your model from the Simulink library browser, under Embedded Coder Support Package for TI C2000 > F2837xD
- Drag a sine wave source block from Simulink source blocks, double-click on the sine wave and select “Sample based” for the sine type, set the Amplitude to 2047.5, Bias 2047.5, Samples per period: 100, Sample time: .01 → this will generate a 1Hz sine wave with 100 points oscillating from 0 to 4095, which is the range that the DAC wants.
- Connect the Sine wave to the DAC
- Make sure your board is connected to your computer and generate code for the model (Ctrl+B)
