# xxx 开发板的Arduino生态兼容说明
|
||
|
||
## 1 RTduino - RT-Thread的Arduino生态兼容层
|
||
|
||
xxx 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
|
||
|
||
更多引脚布局相关信息参见 [pins_arduino.c](pins_arduino.c) 和 [pins_arduino.h](pins_arduino.h)。
