+# lpc55s69_nxp_evk开发板的Arduino生态兼容说明
+
+## 1 RTduino - RT-Thread的Arduino生态兼容层
+
+lpc55s69_nxp_evk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)。
