This add-on is for R2019a or higher releases.
This add-on library extends MATLAB Support Package for Arduino Hardware to read from L3G gyros. With the add-on, you can read measured angular velocity in radians per second. Supported boards are L3GD20H, L3GD20, and L3G4200D.
Sample usage:
Create arduino object with the add-on library
a = arduino('COM38', 'Uno', 'Libraries', 'Pololu/L3G');
Create L3G object
gyro = addon(a, 'Pololu/L3G');
Obtain angular velocity
vel = readAngularVelocity(gyro);
It includes documentation and an example that demonstrates the use with L3G gyro to get angular velocity.
Important: Before using this add-on library in MATLAB, you need to install the L3G Arduino library. Here are the instructions:
Installation:
  1. Download the zip file from https://github.com/pololu/l3g-arduino/archive/2.0.0.zip
  2. Unpackage the zip into local directory.
  3. Move the ‘L3G’ folder inside the unzipped folder into the "libraries" folder inside your Arduino sketchbook folder. You may need to create the folder if it does not already exist:
For R2019a:
  • On Windows®, the default path is "Documents\Arduino\libraries\"
  • On Mac®, the default path is "~/Documents/Arduino/libraries/"
  • On Linux®, the default path is "/home/<username>/Arduino/libraries"
For R2019b and later:
  • On Windows®, the default path is "Arduino IDE Path\portable\sketchbook\libraries\"
  • On Mac®, the default path is "~/Documents/Arduino/libraries/"
  • On Linux®, the default path is "Arduino IDE Path/portable/sketchbook/libraries/"
Note: Arduino IDE Path is returned by the following command in the MATLAB Command Window
arduinoio.IDERoot
For R2024a and later, across all operating systems, the library location can be determined by executing the following command:
fullfile(arduinoio.CLIRoot, 'user','libraries')
Troubleshooting tips:
  1. After installing this add-on library and the required Arduino library, type "listArduinoLibraries" in MATLAB to see if the add-on is properly installed.
  2. Wire up the Arduino board and the add-on device properly before creating the object to avoid a connection error in MATLAB.
  3. Refer to the documentation for details on usage and syntax. It can be found under Supplemental Software in the product documentation.
