Blue Bridge Cup multi interface switching processing (enumeration plus state machine method)

Preface

In this paper, we mainly introduce how to deal with the problem of multi interface switching in the Blue Bridge Cup .

One 、 What is multi interface switching

Multi interface switching is that the title requires a specific interface to be displayed in the case of characteristics , At this time, we need to switch the interface .

Two 、 Code display

#include <STC15F2K60S2.H>

static void DIP_ser(void)// Handling multiple interfaces 
static void key_scan(void);// Press the key to switch the interface 

typedef enum
{
    
	ID_NULL=0,
	ID_1,// Interface 1
	ID_2,// Interface 2
	ID_3,// Interface 3
	
}ID_DATA;

ID_DATA id_data;// Declare an enumeration variable 

void DIP_ser(void)
{
    
	switch(id_data)
	{
    
		case ID_1:
		{
    
			// Interface 1 Function main body 
		}
		break;
		case ID_2:
		{
    
			// Interface 2 Function main body 
		}
		break;
		case ID_3:
		{
    
			// Interface 3 Function main body 
		}
		break;
	}
}

void key_scan(void)
{
    
	// Operate enumeration variables to achieve interface switching 
	( There is no need to explain this part of the code , Press the key to change id_data that will do )	
}

void main()
{
    
	id_data=ID_1;// Power on initialization interface 1( You can also change to other interfaces )
	while(1)
	{
    
		key_scan();
		DIP_ser();
	}
}

summary

Using this method to switch the interface is simple and clear , The code will look clearer .
