This add-on extends MATLAB Support Package for Arduino Hardware to read from and write to 1-Wire devices. With the add-on, you can reset the device, read or write a single byte or multiple bytes from or to the device and also check the data integrity using either CRC8 or CRC16 algorithm.
Sample usage:
Create arduino object with the add-on library
a = arduino('COM38', 'Uno', 'Libraries', 'PaulStoffregen/OneWire');
Create 1-Wire object
sensor = addon(a, 'PaulStoffregen/OneWire');
Obtain sensor ROM address
addr = sensor.AvailableAddresses{1};
Reset sensor
reset(sensor);
Write to sensor
write(sensor, addr, 72, 1) % parasite power on
Read 9 bytes from sensor
read(sensor, addr, 9)
Check CRC of received data
checkCRC(sensor, [1 2 3 4], 56, crc8)
It includes documentation and an example that demonstrates the use with a DS18B20 temperature sensor and DS2431 1024-bit EEPROM.
Important: Before using this add-on library in MATLAB, you need to install the OneWire Arduino library. Here are the instructions:
Installation
  1. Download the zip file from https://github.com/PaulStoffregen/OneWire/archive/v2.3.2.zip
  2. Unpackage the zip into local directory and rename the folder to ‘OneWire’.
  3. Move the ‘OneWire’ folder into the "libraries" folder inside your Arduino sketchbook folder:
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.
