Simulink (Embedded Coder) Target for TI Stellaris LaunchPad



Simulink (Embedded Coder) Target for TI Stellaris LaunchPad
TI Stellaris LaunchPad ( is a low-cost development board based on ARM Cortex-M4F.
Simulink ( is a leading environment for multidomain simulation and Model-Based Design.

Embedded Coder ( allows you to generate C code and deploy your algorithms to target hardware.

Please refer to this repository: for the latest development version. Your input and feedback is highly appreciated!


1) Windows/Linux: Have Code Composer Studio 5.3 (or above) installed (

2) Windows/Linux: Have StellarisWare installed ( You don't have to download the complete StellarisWare package. "StellarisWare for the Stellaris LM4F120 LaunchPad Evaluation Board" is enough.

Make sure your toolchain is working (build and download some test project, check connection) before you proceed!

3) Make sure you have a working/supported host compiler ( by running

    mex -setup


4) Extract this package somewhere. Make sure there are no spaces/non-ASCII characters in path (just in case).

5) Within MATLAB, 'cd' to the directory containing stellaris_setup.m and run this script.

You should be good to go.

What this package already has:

    Standalone execution on target (driven by ISR)
    Execution in PIL mode
    PIL mode profiling

    Simulink library blocks for:

    * GPIO
    * Push Buttons
    * UART Read/Write
    * Built-in temperature sensor
    * Generic ADC

What this package would like to have:

    Simulink library blocks for:

    * PWM, Interrupts, uDMA...
    * Timers

    More documentation

    External Mode support

Can someone who has done the porting to the Tiva-C Launchpads upload their files?

For the TivaC Launchpad the Serial Transmit only works for the port 0, if you change the port for 1,2 or 3 the value will be ignored, and the transmission will be done by the port 0.

This package doesn't support Tiva-C directly. You need to make modifications. Specifically, you should refer to porting guide for Stellaris->Tiva-C, that explains how data types handling has changed (hence your error about undefined data type indentifier).


I have encountered a problem while building. Diagnostic viewer shows "C:/ti/TivaWare_C_Series-", line 582: error: identifier "uint32_t" is undefined " in "main_stellaris_test_gpio.c".
and some other errors, help me iam using tiva c launchpad. thanks

I think Stellaris and Tiva are mostly binary compatible, means you can download binary compiled for Stellaris on Tiva and it will work. The only thing is that Tiva has a bit more peripheral. The CCS version do matters. Use CCS 5.3 (not later version) or you will have to patch the compile part if I remember it right.

It is possible to use it with TivaC, and i heard from users who successfully used it after just changing (renaming) according options/binary names etc. I don't have TivaC, so can't help you with that - but it should be pretty straightforward.

Thanks for your great contribution!

Is it possible to use this target with the new Tiva™ C Series TM4C123G LaunchPad that replaced the Stellaris® LM4F120 LaunchPad? Both are using the same ARM Cortex M4F chip.

Do you have any experience with the new board?
