> 1. Don't use a same hardware timer to drive PWM (analogRead) and servos at same time, because hardware timer can only generate a same frequency for 4 PWM channels. Otherwise, it could cause a failure when drive servos.

## 3 Communication
## 3 通信
### 3.1 I2C Bus
### 3.1 I2C总线
I2C bus is `SCL/D15` and `SDA/D14` pins. Users can directly include the `#include <Wire.h>`, which is the Arduino official I2C header file, to use the I2C bus.
STM32F469 Discovery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 Bus
### 3.2 SPI总线
This board doesn't support Arduino SPI header file and functions.
目前本BSP不支持使用Arduino的SPI功能。
### 3.3 Serial
### 3.3 串口
This board supports to use `Serial.` method to operate `uart3` device. See [example](https://github.com/RTduino/RTduino/blob/master/examples/Basic/helloworld.cpp).
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)。
### 3.4 USB Virtual Serial
This board supports USB virtual serial. See [example](https://github.com/RTduino/RTduino/tree/master/examples/USBSerial). You may enable it if is needed.

# STM32F469 Discovery开发板的Arduino生态兼容说明
[English](README.md) | **中文**
## 1 RTduino - RT-Thread的Arduino生态兼容层
STM32F469 Discovery开发板已经完整适配了[RTduino软件包](https://github.com/RTduino/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/RTduino/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 --->
[*] Compatible with Arduino Ecosystem (RTduino)
```
## 2 Arduino引脚排布
![disco-f469-pinout](disco-f469-pinout.png)
该BSP遵照Arduino UNO板的引脚排列方式，详见 [pins_arduino.c](pins_arduino.c) 和 [pins_arduino.h](pins_arduino.h)。

> 注意：
>
> 1. 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。
