GD32F103VE点灯主要用来学习端口引脚的输出配置。它由LED.c，LED.h，SoftDelay.c和main.c组成。

#include "gd32f10x.h" //使能uint8_t,uint16_t,uint32_t,uint64_t,int8_t,int16_t,int32_t,int64_t
#include "SoftDelay.h"#include "LED.h"int main(void)
{LED_Init();//初始化MCU_Led指示灯端口while(1){MCU_Led_On();delay_X_ms(200);//软件延时200msMCU_Led_Off();		delay_X_ms(200);//软件延时200ms}
}

#define __LED_H#include "gd32f10x.h" //使能uint8_t,uint16_t,uint32_t,uint64_t,int8_t,int16_t,int32_t,int64_t#define MCU_Led_Off()  GPIO_BOP(GPIOD)=GPIO_PIN_15  //GD15输出高电平
#define MCU_Led_On() GPIO_BC(GPIOD)=GPIO_PIN_15   //GD15输出低电平
#define MCU_Led_Toggle() gpio_bit_write( GPIOD,GPIO_PIN_15,(bit_status)((1-gpio_input_bit_get(GPIOD,GPIO_PIN_15))) )
//GD15取反输出电平extern void LED_Init(void);#endif

#include "LED.h"void LED_Init(void);//函数功能:初始化MCU_Led指示灯
void LED_Init(void)
{rcu_periph_clock_enable(RCU_GPIOD);//使能GPIOD时钟,enable GPIO clockgpio_init(GPIOD, GPIO_MODE_OUT_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_15);//将GPIOD15设置为输出上拉MCU_Led_Off();
//	GPIO_BC(GPIOD) = GPIO_PIN_15;//清除GPIOD15输出,GPIO bit clear register
}

#include "SoftDelay.h" //使能uint8_t,uint16_t,uint32_t,uint64_t,int8_t,int16_t,int32_t,int64_tvoid delay_X_us(uint16_t i)
{uint16_t cnt;while(i--){cnt=7;while(cnt--);}
}void delay_X_ms(uint16_t i)
{uint16_t cnt;while(i--){cnt=8000;while(cnt--);}
}

 main.c如下：

#include "gd32f10x.h" //使能uint8_t,uint16_t,uint32_t,uint64_t,int8_t,int16_t,int32_t,int64_t
#include "SoftDelay.h"#include "LED.h"int main(void)
{LED_Init();//初始化MCU_Led指示灯端口while(1){MCU_Led_On();delay_X_ms(200);//软件延时200msMCU_Led_Off();		delay_X_ms(200);//软件延时200ms}
}
