Question

The project aims to create a program to shows a scoreboard on the microcontroller. The following program is my menu to shows the scoreboard,please help me check my program

scoreboard layout

Program:

#include <p18f46K20.h>

#include <stdio.h>

#include <stdlib.h>

#include <stdio.h>

#include "delays.h"

#include "oled_interface.h"

#include "oled_jib.h"

#include "oled_cmd.h"

#include <math.h>

#define switch1 PORTBbits.RB0

#define switch2 PORTBbits.RB1

#define switch3 PORTBbits.RB2

#define switch4 PORTBbits.RB3

enum type {main,Home_Team,Guests_Team};

char echo[100];

unsigned int argument[6];

int x=0,y=0,m=0,n=0;

//x, y stand for two teams score and m,n stand for match

/************* D E C L A R A T I O N S *******************/

void InitializeSystem(void);

void scoreboard(void);

unsigned char scoreboard(void);

int Getkey(void); //A blocking function that waits for a key to be pressed. This function handles the [MENU] key.

void InitializeSystem(void);

void main(void)

{

char temp;

int x,y,m,n;

int x=0;

int y=0;

int m=0;

int n=0;

enum type state = MAIN;

InitializeSystem();

delay = 30000;

while(delay--);

// These are the functions you need to use to initialise the display

oled_init();

oled_clear();

oled_refresh();

//Type the match of sports event

typedef struct

{

char scoreHome_Team; //Home team win in the period

char scoreGuests_Team;

}match_t;

//Type the points of sports event in one match

typedef struct

{

char Home_Teamn; //Home team got 1 point in the match

char Guests_Teamn;

match_t match[7]; // Maximum 7 matches

}score_t;

}

while (1)

{

switch(state)

{

case (MAIN):

{

Delay10KTCYx(250);

oled_clear();

oled_fixeds_1x("Team Period Digits Home Guest");

oled_refresh();

} break;
