## 使用说明
|
|||
|
|
|
|||
|
|
本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
|
|||
|
|
|
|||
|
|
### 快速上手
|
|||
|
|
|
|||
|
|
本 BSP 为开发者提供 MDK5工程，IAR工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
|
|||
|
|
|
|||
|
|
#### 硬件连接
|
|||
|
|
|
|||
|
|
使用数据线连接开发板到 PC，打开电源开关。
|
|||
|
|
|
|||
|
|
#### 编译下载
|
|||
|
|
|
|||
|
|
双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
|
|||
|
|
|
|||
|
|
#### 运行结果
|
|||
|
|
|
|||
|
|
下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，LED3 会周期性闪烁。
|
|||
|
|
|
|||
|
|
连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，在串口上可以看到 RT-Thread 的输出信息:
|
|||
|
|
|
|||
