HT32F52352 点灯+HT32延时函数_ht32f52367的延时

首先知道在HT32F52352中有两个可用的LED灯

 

可以看出对应为PC14         PC15

当PC15 PC14 为低电平时LED亮

led.h

#ifndef _LED_H
#define _LED_H
 
#include "ht32f5xxxx_01.h"
 
 
void LED_init(void);
 
#endif
 

led.c

#include "led.h"
 
 
static void RCC_init()						//时钟配置
{
	CKCU_PeripClockConfig_TypeDef CCLOCK = {{0}};		//不开启外设时钟相应功能无法使用
	
	CCLOCK.Bit.PC    = 1;								//开启PC时钟
	CCLOCK.Bit.AFIO  = 1;								//开启复用功能时钟
	CKCU_PeripClockConfig(CCLOCK, ENABLE);				//使能时钟
}
 
static void LED_GPIO_init()
{
	HT_GPIO_TypeDef* LED_gpio;
	LED_gpio=HT_GPIOC;
	
	AFIO_GPxConfig(GPIO_PC, GPIO_PIN_14 | GPIO_PIN_15, AFIO_FUN_GPIO);	//配置GPIO模式
	
	GPIO_DirectionConfig(LED_gpio, GPIO_PIN_14 | GPIO_PIN_15, GPIO_DIR_OUT);	
    //配置GPIO输出      输入GPIO_DIR_IN  输出GPIO_DIR_OUT
 
	GPIO_PullResistorConfig(LED_gpio, GPIO_PIN_14 | GPIO_PIN_15, GPIO_PR_DISABLE);	
    //配置上下拉     上拉­GPIO_PR_UP   下拉­GPIO_PR_DOWN
 
	GPIO_DriveConfig(LED_gpio, GPIO_PIN_14 | GPIO_PIN_15, GPIO_DV_8MA);		
    //选择GPIO引脚驱动电压     GPIO_DV_4/8/12/16MA 
}
 
void LED_init()
{
	RCC_init();
	LED_GPIO_init();
}

 main.c

int main(void)
{
  GPIO_Configuration();
 
  LED_init();
	//0为低电平    1为高电平
    //因为低电平LED亮    所以0 LED亮    1 LED灭
  while (1)
  {
	GPIO_WriteOutBits(HT_GPIOC,GPIO_PIN_14 | GPIO_PIN_15,0);
	delay_ms(500);
	GPIO_WriteOutBits(HT_GPIOC,GPIO_PIN_14 | GPIO_PIN_15,1);
	delay_ms(500);
 
  }
}

因为上面会用到延时函数

所以：

delay.h

#ifndef __DELAY_H
#define __DELAY_H 			   
#include "ht32_cm0plus_misc.h"
void delay_s(u16 s);
void delay_ms(u16 ms);
void delay_us(u32 us);
#endif
 
 

delay.c

#include "ht32_cm0plus_misc.h"
#include "delay.h"
//mS
void delay_us(u32 us)
{
	u32 i;
	SYSTICK_ClockSourceConfig(SYSTICK_SRC_STCLK);          //
	SYSTICK_SetReloadValue(SystemCoreClock / 8 / 1000000); //
	SYSTICK_IntConfig(DISABLE);                            // 
	SYSTICK_CounterCmd(SYSTICK_COUNTER_CLEAR);             //
	SYSTICK_CounterCmd(SYSTICK_COUNTER_ENABLE);            //
	for( i = 0;i < us;i++ )
	{
		while( !( (SysTick->CTRL) & (1<<16) ) ); 
	}
 
	SYSTICK_CounterCmd(SYSTICK_COUNTER_DISABLE); //
	SYSTICK_CounterCmd(SYSTICK_COUNTER_CLEAR);	 //
}
 
void delay_ms(u16 ms){ //mS 
	while( ms-- != 0){
		delay_us(1000);	//1000
	}
}
 
void delay_s(u16 s){ //S	 		  	  
	while( s-- != 0){
		delay_ms(1000);	//1000
	}
}

实现两个LED灯500ms一闪一灭

注意：烧录程序后，需给单片机断电后，再供电才能实现功能，或者点复位按钮
