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:
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/"
Arduino IDE Path is returned by the command arduinoio.IDERoot in the MATLAB Command Window

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.
