I2C 设备
R2026b在使用 I2C 函数之前，请使用 arduino 创建一个 Arduino 对象。有关详细信息，请参阅Connect to Arduino Hardware。您可以使用 Arduino 资源管理器以交互方式配置 I2C 通信接口，并使用该接口在 MATLAB® 和 MATLAB Online™ 中对连接到 Arduino 和其他受支持硬件的 I2C 设备读取和写入数据。有关详细信息，请参阅 Connect to I2C Device Using Arduino Explorer App。
有关安装版 MATLAB 中支持的硬件的完整列表，请参阅Supported Hardware。有关 MATLAB Online 支持的板、工作流和平台的详细信息，请参阅Get Started with MATLAB Online for Arduino。
注意
除 scanI2CBus 之外的所有函数都使用 MATLAB Function 模块生成代码。有关详细信息，请参阅Deploy Arduino Functions to Arduino Hardware Using MATLAB Function Block。
