So the Wire library that is used when compiling for the Uno is completely different from the one used when compiling for the Nano 33 IoT, and so on. Each boards platform has its own version of the Wire library. Note that you might have multiple versions of a library installed on your computer and the active version may depend on which board you compile for.
It can be found under Supplemental Software in the product documentation.Hi I'll share a technique you can use to find the location of most any library. 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.
