I already finished the source but i couldnt combine these source please help me

( i use atmega 128 program at codevision. And simulate at Proteus)

1. if any button SW0~SW7 ,Create a program that sound and LED like a button on a scale.

#include

void delay(int I) //time delay function

{

while(i--);

}

void main(void)

{

DDRC=0xFF; //LED control setting

PORTC=0xFF; //Setting LED as a Output port

DDRD=0x00; //Setting tact swtich as a input Port

DDRG=0xFF; //setting speaker as a output port

while(1)

{

if (PIND==(0x7F)) //If press button SW7 create a program that sounds like a button on a scale and LED

{

PORTC=0x7F;

PORTG=0x00;

delay(3906*0.5);

PORTG=0x01;

delay(3906*0.5);

}

if (PIND==0xBF) ////If press button SW6 create a program that sounds like a button on a scale and LED

{

PORTC=0xBF;

PORTG=0x00;

delay(3906*0.5333);

PORTG=0x01;

delay(3906*0.5333);

}

if (PIND==0xDF)

{

PORTC=0xDF;

PORTG=0x00;

delay(3906*0.6);

PORTG=0x01;

delay(3906*0.6);

}

if (PIND==0xEF)

{

PORTC=0xEF;

PORTG=0x00;

delay(3906*0.6666);

PORTG=0x01;

delay(3906*0.6666);

}

if (PIND==0xF7)

{

PORTC=0xF7;

PORTG=0x00;

delay(3906*0.75);

PORTG=0x01;

delay(3906*0.75);

}

if (PIND==0xFB)

{

PORTC=0xFB;

PORTG=0x00;

delay(3906*0.8);

PORTG=0x01;

delay(3906*0.8);

}

if (PIND==0xFD)

{

PORTC=0xFD;

PORTG=0x00;

delay(3906*0.8888);

PORTG=0x01;

delay(3906*0.8888);

}

if (PIND==0xFE)

{

PORTC=0xFE;

PORTG=0x00;

delay(3906);

PORTG=0x01;

delay(3906);

}

}

}

2. If press button SW0&SW1 create a program that time clock would be shown.

#include

int position=0,BJT[4]={0xFE,0xFD,0xFB,0xF7};

int number=0,segment[10]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90};

int msec=0, sec=0, min=0;

int switch [8]={0x7E, 0xBF, 0xDF, 0xE7, 0xFB, 0xFD, 0xFE};

void main()

{

DDRA=0xFF;

PORTA=0XFF;

DDRB=0xFF;

PORTB=0xFF;

DDRD=0x00;

TCCR0=0x04;

TIMSK=0x01;

SREG=0x80;

while(1){}

}

interrupt[TIM0_OVF]void timer0_ovf_isr()

{

TCNT0=0x06;

if(PIND==0xFC)

{PORTA=BJT[position];

if(position==0)number=sec%10;

if(position==1)number=sec/10;

if(position==2)number=min%10;

if(position==3)number=min/10;

PORTB=segment[number];

position++;

if(position>3)position=0;

msec++;

if(msec==1000)

{

msec=0;

sec++;

}

if(sec==60)

{

sec=0;

min++;

}

if(min==60)min=0;

}

}
