The SCL line carries the clock signal used for communication timing. The SDA wire is used for sending the actual data back and forth between the master and slave devices. The BusĪn I2C bus is simply two wires that connect all of the I2C devices in the network. When sending data on the bus, only one device can send data at a time. Slave devices respond to whatever a master device sends. Master devices can send and receive data. The I2C address makes it possible for a master device to send data to a particular slave device on the bus. Slave DevicesĮach slave device has an I2C address that is used to identify the device. I2C networks can have multiple master devices and slave devices. The master and slave devices are connected by a bus. The I2C NetworkĪn I2C network consists of a master device and a slave device. It covers all of the steps, diagrams, and code you need to get started. It can be found under Supplemental Software in the product documentation.BONUS: I made a quick start guide for this tutorial that you can download and go back to later if you can’t set this up right now. Refer to the documentation for details on usage and syntax.
Wire up the Arduino board and the add-on device properly before creating the object to avoid a connection error in MATLAB.ģ. After installing this add-on library and the required Arduino library, type "listArduinoLibraries" in MATLAB to see if the add-on is properly installed.Ģ. On Linux, the default path is "/home//Arduino/libraries"ġ. On Mac, the default path is "~/Documents/Arduino/libraries/" On Windows, the default path is "My Documents\Arduino\libraries\" Move the ‘OneWire’ folder into the "libraries" folder inside your Arduino sketchbook folder: Unpackage the zip into local directory and rename the folder to ‘OneWire’.ģ. Important: Before using this add-on library in MATLAB, you need to install the OneWire Arduino library. It includes documentation and an example that demonstrates the use with a DS18B20 temperature sensor and DS2431 1024-bit EEPROM. Write(sensor, addr, 72, 1) % parasite power on Sensor = addon(a, 'PaulStoffregen/OneWire') % Create arduino object with the add-on libraryĪ = arduino('COM38', 'Uno', 'Libraries', 'PaulStoffregen/OneWire') 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.
This add-on extends MATLAB Support Package for Arduino Hardware to read from and write to 1-Wire devices.
This add-on is supported for MATLAB R2016a - R2018b.
