如何補全這avr單片機程序，還要有按鍵檢測、延時去抖，等待抬起等環節。需要怎么補？

單片機源程序如下:

#include <iom16v.h>

#define  uint unsigned int

void delay10ms(void)
{
uint t;
for( t=0;t<1360;t++);
}

void main(void)
{
SFIOR&=0xFB;
      DDRA = 0x00;                                              /*A口輸入*/
      PORTA = 0xFF;                                              /*A口上拉*/
DDRB = 0xFF;                                              /*B口輸出*/
      PORTB = 0xFF;                                              /*LED全滅*/
      DDRC = 0xFF;
      PORTC = 0xFF;
      DDRD = 0x00;
      PORTD = 0xFF;

      while (1) {
            if ((PINA & (1 << PA0)) == 0)
               {
                  delay10ms();
                        if ((PINA & (1 << PA0)) == 0)
                        while((PINA & (1 << PA0)) == 0);//??????
                        PORTB = ~(1 << PB0);             /*?????*/
                     }
            if ((PINA & (1 << PA1)) == 0)
                  {

                     PORTB = ~(1 << PB2);
                     }

                     }
            if ((PINA & (1 << PA6)) == 0)
                  {

                     PORTB = ~(1 << PB6);
