Android Support from Simulink

Capabilities and Features

Simulink^® Support Package for Android™ Devices lets you program and run algorithms on Android smartphones and tablets. The support package includes a library of Simulink blocks for accessing the device's sensors, capturing and playing audio and video, creating UI widgets and communicating with other devices through a network interface.

You can design signal or image processing algorithms and applications for Android devices from Simulink. You can monitor and fine-tune the application using the sensors of your smartphone or tablet. Then you can deploy the finished application to your Android hardware with the click of a button.

The support package includes:

Library of Simulink blocks that program your Android device I/O, including inputs such as accelerometers, gyroscopes, magnetic field, ambient temperature, camera, location (GPS), humidity, light, pressure; and outputs to the device display and speaker
Interactive parameter tuning of outputs and signal monitoring of sensor inputs for applications running on your Android smartphone or tablet
ThingSpeak™ read and write blocks to send and receive data between the mobile device and ThingSpeak
Data logging from sensors and signals into MAT files saved on the Android device
Model deployment on a mobile app for standalone operation on the device. The app can include touchscreen widgets, such as sliders, buttons, scopes, text, and data displays, and communicate to other hardware via TCP/IP, UDP, and Bluetooth^®
Generation of Android Studio compatible projects

Working with Android™ Devices Block Library

This example shows how to use blocks from the Simulink Support Package for Android Devices to create a Simulink® model and run it on an Android device.

Introduction

Simulink Support Package for Android Devices enables you to create and run Simulink models on Android devices. The support package includes a library of Simulink blocks for using device sensors and network interfaces.

In this example you will learn how to create and run Simulink models that use Audio blocks, GUI blocks like the Slider, sensor blocks like the Gyroscope, and communication blocks like the UDP Send and Receive.

Prerequisites

We recommend completing Getting Started with Android™ Devices example

Required Hardware

Android device, configured using androidhwsetup
USB cable to connect the device to host computer
Headphones with microphone

Task 1 - Setting up the device

In this task, you will ensure that you are able to communicate with your device.

1. Connect your Android device to your host computer.

3. Connect the headphone with microphone to the audio jack on the device.

Task 2 - Audio

In this task, you will learn to use Audio Capture, Audio Playback and Slider.

1. Open the Audio Usage Example model.

2. In your Simulink model, click Simulation > Model Configuration Parameters to open Configuration Parameters dialog.

3. Select the Hardware Implementation pane and review the parameters on the page that opens.

4. In the model, double-click on the Audio Capture block. Note that the Audio sampling frequency is set to 44100 Hz and the Frame size is set to 4410. With these settings, the Audio Capture block will process 4410 samples of audio data for every 0.1 second(4410/44100(Hz)).

5. In the model, double-click on the Audio Playback block. Note that the Audio sampling frequency is set to 44100 Hz to match the setting in Audio Capture block.

6. In the model, double-click on the Slider block. Note that the Minimum, Initial value and Maximum are set to 0, 1 and 2.

7. In the model, click the Deploy to Hardware button on the toolbar.

8. As the model is running on the device, you will hear audio from the speakers/headphones connected to the device. When you slide the slider, you will hear the audio volume change.

9. Other Things to Try: You can change the Audio Sampling frequency to other values and deploy the model to your device.

Task 3 - Play audio file

In this task, you will learn to use Audio File Read.

1. Open the Audio File Read Example model.

2. In the model, note that the Audio File Read block reads a mono audio file with 44100 Hz sampling frequency. Double-click on the Audio File Read block. Note that Frame size is set to 4410. With these settings, the Audio File Read block will process 4410 samples of audio data for every 0.1 second(4410/44100(Hz)).

3. In the model, double-click on the Audio Playback block. Note that the Audio sampling frequency is set to 44100 Hz to match the sampling frequency of the audio file.

4. In the model, note that Matrix Concatenate is used to construct stereo audio data from the mono audio data.

5. In the model, click the Deploy to Hardware button on the toolbar.

6. As the model is running on the device, you will hear the music.

7. Other Things to Try: Select another music file to play.

Task 4 - Sensor Blocks with UDP

In this task, you will learn to use sensor blocks and communication blocks.

1. Open the Sensor and UDP Usage Example model.

2. In your Simulink model, click Simulation > Model Configuration Parameters to open Configuration Parameters dialog.

3. Select the Hardware Implementation pane and review the parameters on the page that opens.

4. In the model, double-click on the Gyroscope block and observe the Sample time parameter is set to 0.1. Double-click on the Light Sensor block and observe the same. This ensures that both run at the same rate.

5. In the model, double-click on the UDP Send blocks and observe that the Remote IP address is set to broadcast. Also, observe that the two blocks send data to two different ports: 25000 and 25001.

6. In the model, click the Deploy to Hardware button on the toolbar.

7. As the model is running on the device, the Gyroscope data and Light sensor data are sent over UDP.

Task 5 - UDP Receive block

In this task, you will learn to use the UDP Receive block.
