简单为美-编程思路

系统时钟1ms++，理论可正常工作49天。

uint32_t getSysTick(void)
{
     
	return jiffies;
}


void SysTick_Handler(void)
{
    
	jiffies++;
}

GPIO的OUTPUT输出任务

void GPIO_driver_task(void)
{
    
	static int GPIO_gap_time = 10;
	static int GPIO_drv_start_time = 0;
	static int GPIO_is_run = 0;
	if (getSysTick()>GPIO_drv_start_time)
	{
    
		GPIO_drv_start_time = getSysTick();
		GPIO_drv_start_time += led_gap_time;
		GPIO_is_run = 1;
		
	}
	if(GPIO_is_run == 1)
	{
    
		GPIO_is_run = hal_GPIO_Driver();
	}
}

GPIO的OUTPUT的状态函数

int hal_GPIO_Driver(void)
{
    
	static int step = 0;
	switch(step)
	{
    
	case enum1:{
     GPIO_function1(); step = enum2; 	return 1;}
	case enum2:{
     GPIO_function2(); step = enum3; 	return 1;}
	case enum3:{
     GPIO_function3(); step = enum4; 	return 1;}
	case enum4:{
     GPIO_function4(); step = enum5; 	return 1;}
	case enum5:{
     GPIO_function5(); step = enum6; 	return 1;}
	case enum6:{
     GPIO_function6(); step = finish; 	return 1;}
	default:{
    					   step = enum1;	return 0;}
	}
}

GPIO_function1函数说明

unsigned short Led_Dark[] = 		{
    0,1,LED_EFFECT_END};

    1,10,0,80,1,50,0,50,LED_EFFECT_AGN,4};


int GPIO_function1(void)
{
    
	for(unsigned char i=0; i<LED_SUM; i++)
	{
    
		if(Ledx[i].Led_Timer)
		{
    
			Ledx[i].Led_Timer--;
		}
		if( !Ledx[i].Led_Timer )
		{
    	
			if(*(Ledx[i].pLed_State+2) == LED_EFFECT_END){

	return 0;
