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

|
||||||
|
|
||||||
|
### 3.2 SPI总线
|
||||||
|
|
||||||
|
目前本BSP不支持使用Arduino的SPI功能。
|
||||||
|
|
||||||
|
### 3.3 串口
|
||||||
|
|
||||||
|
本BSP通过 `Serial.` 方法调用 `uart2` 串口设备。详见[例程](https://github.com/RTduino/RTduino/blob/master/examples/Basic/helloworld.cpp)。

|
### 3.1 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。

### 3.2 SPI总线
|
||||||
|
|
||||||
|
目前本BSP不支持使用Arduino的SPI功能。
|
||||||
|
|
||||||
|
### 3.3 串口
|
||||||
|
|
||||||
|
本BSP通过 `Serial.` 方法调用 `uart2` 串口设备。详见[例程](https://github.com/RTduino/RTduino/blob/master/examples/Basic/helloworld.cpp)。

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。
