Once you download the library ZIP file you’ll need to install it in your Arduino IDE. To do this follow these instructions: Open the Arduino IDE. Click on the Sketch menu at the top of the IDE. Choose Include Library from the drop-down menu. Select Add.ZIP Library from the sub-menu. A dialog box will open.

This add-on is supported for MATLAB R2016a - R2018b.

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:
On Windows, the default path is 'My DocumentsArduinolibraries'
On Mac, the default path is '~/Documents/Arduino/libraries/'
On Linux, the default path is '/home/<username>/Arduino/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.
