### 【N32G457】基于RT-Thread和N32G457的点灯demo
**一、硬件电路**

不难发现单片机输出高电平，LED将被点亮；反之，LED熄灭。这是一个非常简单的原理。

**二、软件开发**
开发工具：rt-thread studio
1. 点击左上角“文件”，新建项目选择RT-Thread项目。设置工程名Project name,选择基于开发板选项。点击完成，等待工程建立。

2.根据硬件电路原理，设计源代码
```
uint32_t Speed = 2000;
    /* set LED pin mode to output */
    rt_pin_mode(LED1_PIN, PIN_MODE_OUTPUT);
    rt_pin_mode(LED2_PIN, PIN_MODE_OUTPUT);
    rt_pin_mode(LED3_PIN, PIN_MODE_OUTPUT);
    while (1)
    {
        rt_pin_write(LED3_PIN, PIN_LOW);
        rt_pin_write(LED2_PIN, PIN_LOW);
        rt_pin_write(LED1_PIN, PIN_LOW);
        rt_thread_mdelay(Speed);
       rt_pin_write(LED1_PIN, PIN_HIGH);
       rt_pin_write(LED2_PIN, PIN_HIGH);
       rt_pin_write(LED3_PIN, PIN_HIGH);
       rt_thread_mdelay(Speed);
    }
```
3.编译工程
