Arduino Software From Matlab And Simulink Tutorial

Arduino programming is supposed to be fun but can become frustrating and time consuming for tasks such as plotting sensor data or incorporating advanced math, signal processing, or controls routines into your projects.

MATLAB® and Simulink® address several challenges with traditional Arduino programming. The products support two primary workflows:

  • Develop algorithms that run standalone on the Arduino device

Read, write, and analyze data from Arduino sensors

MATLAB support package for Arduino lets you write MATLAB programs that read and write data to your Arduino and connected devices such as Adafruit motor shield, I2C, and SPI devices. Because MATLAB is a high-level interpreted language, programming with it is easier than with C/C++ and other compiled languages, and you can see results from I/O instructions immediately—without recompiling. MATLAB includes thousands of built-in math, engineering, and plotting functions that you can use to quickly analyze and visualize data collected from your Arduino.

With MATLAB support package for Arduino, the Arduino is connected to a computer running MATLAB. Processing is done on the computer with MATLAB.

Benefits of using MATLAB for Arduino programming:

  • Read and write sensor data interactively without waiting for your code to compile
  • Analyze your sensor data using thousands of pre-built functions for signal processing, machine learning, mathematical modeling, and more
  • Quickly visualize your data using the vast array of plot types in MATLAB

Develop algorithms that run standalone on the Arduino

Simulink support package for Arduino lets you develop algorithms in Simulink, a block-diagram environment for modeling dynamic systems and developing algorithms, and run them standalone on your Arduino. The support package extends Simulink with blocks for configuring Arduino sensors and reading and writing data from them. After creating your Simulink model, you can simulate it, tune algorithm parameters until you get it just right, and download the completed algorithm for standalone execution on the device. With the MATLAB Function block, you can incorporate MATLAB code into your Simulink model.

With Simulink support package for Arduino, you develop the algorithm in Simulink and deploy to the Arduino using automatic code generation. Processing is then done on the Arduino.

Benefits of using Simulink for Arduino programming:

  • Develop and simulate your algorithms in Simulink and use automatic code generation to run them on the device
  • Incorporate signal processing, control design, state logic, and other advanced math and engineering routines in your hardware projects
  • Interactively tune and optimize parameters as your algorithm runs on the device
  • Easily modify algorithms to run on other low-cost and commercial hardware platforms

Story

This project shows how to program an Arduino Mega 2560 using Simulink to receive the signals from an R/C receiver.

Introduction

One common question when working with different robots is how to use an R/C controller to control it. Standard robotics has the R/C receiver send a servo-style pwm signal directly to the servo motors or the motor controller as indicated by the diagram below with Method 1. Many roboticists look to change this relationship by placing a microcontroller in between the R/C receiver and the motors as shown with Method 2. This allows the user to create fly/drive-by-wire programs on the microcontroller where you can for example, design traction control algorithms. You could even take it one step farther by using one of the channels on the R/C Controller to switch the code between different operating modes i.e. R/C control vs. Automated. This example will show how to program an Arduino Mega 2560 using Simulink to receive R/C signals. A second article will be made to demonstrate a drive-by-wire program with a four-wheel vehicle, and will show how to use one of the channels to switch between remote and autonomous modes.

The output of the R/C receiver consists of 4 servo style signals. Servo signals are pulses with a width of about 1-2 ms and a period of about 20 ms. The length of 1 ms is the minimum pulse, 2 ms is the maximum pulse and 1.5 ms is the neutral pulse. There are two types of servo motors, continuous servos and position servos. For a continuous servo, the length of the pulse corresponds to the speed of rotation. For a position servo, the length of the pulse corresponds to the angular position of the servo. When controlling aircraft with an R/C remote, the receiver is connected to position servos.

Prerequisites

We recommend completing Getting Started with Arduino Mega 2560 Hardware.

Required Hardware

From

To run this example you will need the following hardware:

Controller board:

  • Arduino Mega 2560 board
  • USB cable

Radio Control:

  • Generic R/C controller and receiver

Debug Circuit:

  • 4x LEDs
  • 4x 100 Ohm Resistor

Task 1: Setup the Hardware

  • Connect pins 2, 3, 18, and 19 to the 4 channels on the R/C receiver.

From Matlab And Simulink To Fpgas In Five Easy Steps

  • Supply power to the R/C receiver. I supplied 5V from the Arduino 5V pin to an ESC which then plugged into the receiver.

Task 2: Download the Code

Simulink

Download the RC Receive block from the MathWorks File Exchange.

Task 3: Setup the Environment

Setting up the environment needs to be performed only once per version of MATLAB that you have installed. If you have performed these steps before, please ignore this section.

  • Make sure that a compiler is installed. You can set up the compiler by typing (>> mex –setup) at the MATLAB command window. If no compilers show up when you type this command determine which compiler you should use and download from here:http://www.mathworks.com/support/compilers/current_release/For my Windows 7 machine running MATLAB 64-bit, I am using the Windows SDK 7.1compiler, which is free.
  • Type (>> targetinstaller) to set up the Arduino

Task 4: Setup the Driver Block

Matlab and arduino
  • Setting up the driver block needs to be performed only once. If you change the underlying code in the block, you will need to set up the driver block again.
  • To use the custom driver block, 3 files need to be generated;
  • sfcn_rcreceive_wrapper.cpp
  • sfcn_rcreceive.tlc
  • sfcn_rcinterupt.[mex], where [mex] can be mexw32, mexw64, mexmaci64 depending on your OS and version of MATLAB. For my Windows 7 machine using MATLAB 64-bit, the extension is .mexw64.
  • Open the rcreceive.slx model.
  • Open the “RC Receive” S-function Builder block.
  • Click “Build”
  • Type (>> modify(‘sfcn_rcreceive’) at the MATLAB Command Window

Task 5: Run the model on the Arduino Mega 2560 Board

  • Verify that your working directory or “Current Folder” is the folder where the following files are located (i.e. C:rcdriverblock):
  • rcreceive.slx.
  • sfcn_rcreceive.[mex]
  • sfcn_rcreceive.tlc.
  • sfcn_rcreceive_wrapper.cpp.

2. Open the model “rcreceive” if not opened already.

3. Click the “Run” button to enter external mode.

4. If you move the joysticks corresponding to channels 1,2,3 and 4 on pins 2,3,18, and 19, the corresponding values in the Display block and Scope will change. If the values go over 1750, the corresponding LEDs will turn on.

How does the code work?

This driver block attaches externally triggered interrupts to the pins that are specified in the block. These interrupts are bidirectionally triggered (i.e. when the input goes from high to low or low to high). The code in this block uses the two triggers to measure the length of the input pulse. As the joystick moves in the up or right direction, the pulse gets larger, and the code returns a larger value.

For more information on this, feel free to check out the following blog, which describes the c implementation of the algorithm in the Arduino IDE:
