用法

重要：在创建 I2cDevice 之前，请确保正确设置了 I2C 引脚，尤其是 ESP32 的引脚，确保已安装 nanoFramework.Hardware.ESP32 nuget

//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);

对于 STM32 等其他设备，请确保使用您想要使用的 I2C 总线的预设引脚。
