I2C Devices
R2026bCreate an Arduino object using arduino before you use I2C
functions. See Connect to Arduino Hardware for more information. You can use Arduino
Explorer to interactively configure the I2C communication interface
and use the interface to read and write data to I2C devices connected to
Arduino and other supported hardware in MATLAB® and MATLAB
Online™. For more information, see Connect to I2C Device Using Arduino Explorer App.
For a complete list of hardware supported in the installed version of MATLAB, see Supported Hardware. For more information regarding supported boards, workflows, and platforms supported on MATLAB Online, see Get Started with MATLAB Online for Arduino.
Note
All functions, except scanI2CBus, generate code
using the MATLAB Function block. For more details, see Deploy Arduino Functions to Arduino Hardware Using MATLAB Function Block.
