1、开发环境：
    RT-Thread版本：4.0.3
    操作系统：Windows 10
    RT-Thread Studio版本：2.1.0

微控制器: AB32VG1(32位 RISC-V 处理器)

2、板载介绍

开发板的资料比较少，下图是通过RT-Thread Studio获得的资料信息。本文将通过GPIO模拟控制RGB LED灯实现全彩控制。

3、环境搭建

环境的搭建主要是RT-Thread Studio安装与包管理、项目的创建于配置和程序下载。环境的配置是参考博客文章环境搭建参考。

4、实现全彩LED灯闪烁

（1）LED灯电路图

LED灯采用共阳极连接。

（2）实现代码

/**Includes*********************************************************************/
#include <rtthread.h>
#include "board.h"

int main(void)
{
uint32_t cnt = 0;

uint8_t pin_r = rt_pin_get("PE.1");
uint8_t pin_g = rt_pin_get("PE.4");
uint8_t pin_b = rt_pin_get("PA.2");

rt_pin_mode(pin_r, PIN_MODE_OUTPUT);
rt_pin_mode(pin_g, PIN_MODE_OUTPUT);
rt_pin_mode(pin_b, PIN_MODE_OUTPUT);

while (1)
{
//红
rt_pin_write(pin_r, PIN_LOW);
rt_pin_write(pin_g, PIN_HIGH);
rt_pin_write(pin_b, PIN_HIGH);
rt_thread_mdelay(1000);

//绿
rt_pin_write(pin_r, PIN_HIGH);
rt_pin_write(pin_g, PIN_LOW);
rt_pin_write(pin_b, PIN_HIGH);
rt_thread_mdelay(1000);

//蓝
rt_pin_write(pin_r, PIN_HIGH);
rt_pin_write(pin_g, PIN_HIGH);
rt_pin_write(pin_b, PIN_LOW);
rt_thread_mdelay(1000);

//黄(红+绿)
rt_pin_write(pin_r, PIN_LOW);
rt_pin_write(pin_g, PIN_LOW);
rt_pin_write(pin_b, PIN_HIGH);
rt_thread_mdelay(1000);

//紫(红+蓝)
rt_pin_write(pin_r, PIN_LOW);
rt_pin_write(pin_g, PIN_HIGH);
rt_pin_write(pin_b, PIN_LOW);
rt_thread_mdelay(1000);

//青(绿+蓝)
rt_pin_write(pin_r, PIN_HIGH);
rt_pin_write(pin_g, PIN_LOW);
rt_pin_write(pin_b, PIN_LOW);
rt_thread_mdelay(1000);

//白(红+绿+蓝)
rt_pin_write(pin_r, PIN_LOW);
rt_pin_write(pin_g, PIN_LOW);
rt_pin_write(pin_b, PIN_LOW);
rt_thread_mdelay(1000);

//黑(全部关闭)
rt_pin_write(pin_r, PIN_HIGH);
rt_pin_write(pin_g, PIN_HIGH);
rt_pin_write(pin_b, PIN_HIGH);
rt_thread_mdelay(1000);
cnt++;

}

return 0;
}

恭喜啊，环境搞定啦，话说最后是怎么搞定的？
