Embedded Coder for MCU deployment in Simulink

Introduction

Embedded Coder helps turn your Simulink models into C code that runs on small computers called microcontrollers (MCUs). This makes your designs work in real machines.

You want to control a robot using a small computer inside it.

You need to make your Simulink design run on a car's engine controller.

You want to test your control system on real hardware instead of just simulation.

You are building a smart device that needs fast and efficient code.

You want to save time by automatically creating code instead of writing it by hand.

Syntax

Simulink

1. Open your Simulink model.
2. Go to the 'Apps' tab and select 'Embedded Coder'.
3. Configure the target hardware (choose your MCU).
4. Set code generation options (like optimization level).
5. Click 'Build' to generate and deploy code to the MCU.

You must have Embedded Coder installed as an add-on to Simulink.

Choose the correct MCU to match your hardware for best results.

Examples

This example shows generating code for an ARM Cortex-M4 microcontroller.

Simulink

1. Open Simulink model 'my_controller'.
2. Select Embedded Coder app.
3. Choose 'ARM Cortex-M4' as target hardware.
4. Build the model to generate C code.
5. Deploy code to the MCU using supported programmer.

This example targets a Texas Instruments MCU with speed optimization.

Simulink

1. In Simulink, open 'sensor_processing' model.
2. Use Embedded Coder to select 'TI C2000' MCU.
3. Enable optimization for speed.
4. Build and flash code to the device.

Sample Program

This C code is generated by Embedded Coder from a Simulink model that blinks an LED. The initialize function sets up the MCU, and the step function runs repeatedly to toggle the LED.

Simulink

/* Simulink model: simple_led_blink */
/* This example blinks an LED on an MCU using Embedded Coder generated code */

#include "simple_led_blink.h"

int main(void) {
    /* Initialize hardware */
    simple_led_blink_initialize();

    /* Run forever */
    while (1) {
        simple_led_blink_step();
    }

    return 0;
}

Important Notes

Generated code is optimized for the selected MCU to run efficiently.

You can customize code generation settings to balance speed, size, and readability.

Testing on real hardware is important to verify the generated code works as expected.

Summary

Embedded Coder converts Simulink models into C code for microcontrollers.

It helps deploy control and signal processing algorithms to real devices.

Using Embedded Coder saves time and reduces manual coding errors.
