+# STM32L475潘多拉的Arduino生态兼容说明
+
+## 1 RTduino - RT-Thread的Arduino生态兼容层
+
+STM32L475潘多拉已经完整适配了[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

+## 3 I2C总线
+
+潘多拉Arduino支持三条I2C总线，分别是：i2c1、i2c3 和 i2c4。你可以通过`pins_arduino.h`文件中的 `ARDUINO_DEFAULT_IIC_BUS_NAME` 宏来设定Arduino的I2C总线，**默认为 i2c4 总线**。其中：
+
+- i2c1 为用户总线，PC7 为 SDA，PC6 为 SCL。用户可以通过杜邦线连接其他 I2C 传感器/芯片。
+- i2c3 为板载 I2C 外设总线，连接板载 ICM20608（陀螺仪和加速度传感器） 和 AP3216C（距离和光亮度传感器） 芯片
+- i2c4 为板载 I2C 外设总线，连接板载 AHT10（温湿度传感器） 芯片
+
+> 注意：
+>
+> A4和A5引脚在Arduino UNO中即可以被用于模拟管脚，也可以当做I2C引脚使用。在RTduino中，RTduino的I2C功能是由RT-Thread的I2C设备框架直接接管的，A4和A5引脚被定死为I2C引脚。因此，这两个引脚实际并未被定义。
+>
+> 您只需要知道，如果想要使用I2C功能，只需要修改 `ARDUINO_DEFAULT_IIC_BUS_NAME` 宏的对应名称即可直接使用。与A4和A5这两个标识没有什么关系。
+
+## 4 特殊功能说明
+
+### 4.1 芯片内部ADC通道
+
+本BSP适配了STM32的两个芯片内部ADC通道，可以通过 analogRead 函数来分别获取如下功能：
+
+| 特殊功能 | Arduino引脚编号 | STM32引脚编号 |
+| -------------------- | --------------- | ------------- |
+| 芯片内部参考电压 ADC | A2 | -- |
+| 芯片内部温度 ADC | A3 | -- |
+
+### 4.2 真模拟输出功能 (True Analog Output)
+
+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。
+
+在潘多拉板上，使用PA4来当做真模拟输出功能引脚，使用方法为：
+
+```c
+analogWrite(DAC0, 1024); // STM32的DAC分辨率为12位，因此第二个参数范围可以为0-4095
+```
