 ## 3 I2C总线
 STM32F072 Nucleo板的I2C总线是板上丝印的 `SCL/D15` 和 `SDA/D14` 引脚，这两个引脚是被RT-Thread I2C设备框架接管的，不需要直接操控这两个引脚，直接引用`#include <Wire.h>`（Arduino官方I2C头文件）即可使用。

+# STM32F401 Nucleo开发板的Arduino生态兼容说明
+## 1 RTduino - RT-Thread的Arduino生态兼容层
+STM32F401 Nucleo开发板已经完整适配了[RTduino软件包](https://github.com/mysterywolf/RTduino)，即RT-Thread的Arduino生态兼容层。用户可以按照Arduino的编程习惯来操作该BSP，并且可以使用大量Arduino社区丰富的库，是对RT-Thread生态的极大增强。更多信息，请参见[RTduino软件包说明文档](https://github.com/mysterywolf/RTduino)。
+### 1.1 如何开启针对本BSP的Arduino生态兼容层
+Env 工具下敲入 menuconfig 命令，或者 RT-Thread Studio IDE 下选择 RT-Thread Settings：
+```Kconfig
+Hardware Drivers Config --->
+    Onboard Peripheral Drivers --->
+        [*] Support Arduino
+```
+## 2 Arduino引脚排布

+> 注意：
+>
+> 1. D10引脚是PWM反相位引脚，这是由STM32设计决定的，例如正常的PWM设定占空比是20%，它就是20%。但是对于D10引脚，设定占空比是20%，实际输出的占空比是80%。
+> 2. 驱动舵机和analogWrite函数要选择不同定时器发生的PWM信号引脚，由于STM32的定时器4个通道需要保持相同的频率，如果采用相同的定时器发生的PWM分别驱动舵机和analogWrite，可能会导致舵机失效。
+> 3. USART2是Nucleo板的默认串口，理论应对接到了Arduino引脚编号的D0和D1，但是其实际用于串口通信，因此不允许当做普通IO来使用和操作。如果需要将D0、D1与STM32 USART2的引脚相连，需要手动焊接锡桥SB62、SB63。
+> 4. Nucleo板的Arduino接口中AVDD（即AREF）默认是与VDD相连的，如果需要扩展板提供外部参考电压，需要将SB57锡桥挑开。

+## 3 I2C总线
+STM32F401 Nucleo板的I2C总线是板上丝印的 `SCL/D15` 和 `SDA/D14` 引脚，这两个引脚是被RT-Thread I2C设备框架接管的，不需要直接操控这两个引脚，直接引用`#include <Wire.h>`（Arduino官方I2C头文件）即可使用。

 Arduino的 analogWrite 函数虽为模拟写，但是实际输出的是PWM数字信号，并非真正的模拟信号。这是由于Arduino早期使用的AVR单片机并不支持DAC的功能，因此这个习惯就被保留了下来。但是随着Arduino支持芯片的丰富，部分高级芯片已经内建了DAC（例如Arduino官方板MKR、Zero等），因此Arduino的 analogWrite 函数后续也支持了真模拟输出功能。
