| 昨天就写了个程序就是定时器的中断程序,结果,就是近不了中断 ,用的atmega48的片子  程序如下: /*

 #include <avr/io.h>
 #include <avr/interrupt.h>
 const int seg[10]={0x3f,0x06,0x5b,0x4f,0x66,
 0x6d,0x7d,0x07,0x7f,0x6f};
 unsigned char num;
 void init(void)
 {
 DDRB=0xff;
 PORTB=0x00;
 
 DDRC&=0x00;
 }
 void timer1_init(void)
 {
 cli();
 TCCR1B=0x00;
 TCCR1A=0x00;
 TCNT1H=0x85;
 TCNT1L=0xee;
 TCCR1B=0x04;
 TIMSK1=0x01;
 }
 void delay(int j)
 {
 int a,b;
 for (a=0;a<j;a++)
 for (b=0;b<200;b++);
 }
 }
 void main(void)
 {
 cli();
 init();
 timer0_init();
 sei();
 while(1)
 {
 DDRC|=0x01;
 PORTB=~seg[num];
 PORTC|=0x01;
 delay(2);
 PORTB=seg[num];
 PORTC&=0x00;
 delay(2);
 DDRC&=0x00;
 delay(5);
 }
 }
 #pragma interrupt_handler Timer1_isr:14
 void Timer1_isr(void)
 {
 TCNT1H=0x85;
 TCNT1L=0xEE;
 num++;
 if (num==10)
 {
 num=0;
 }
 
 就是不能进入中断 求大侠帮帮忙~~~郁闷了两天~~
