Question

produes 仿真时出现 invalid opcode 0xffff at pc=0x001c 做的定时器1的中断 程序如下

#include<iom48v.h>
#include<macros.h>

#pragam interrupt_handler led:14

void led()
{

PORTD = ~PORTC;//连接一个led灯
PORTD &= 0x01;
TCNT1H = (65535-31250)/10;
TCNT1L = (65535-31250)%10;

}
void main()
{
DDRD |= BIT(0);

TCCR1B |= BIT(2); //256分频
TCNT1H = (65535-31250)/10;
TCNT1L = (65535-31250)%10;
TIMSK1 |= BIT(0);
SREG |= BIT(7);
while(1);

}
那位大虾帮帮忙啊，谢谢
第四行打错了应该为#include pragma interrupt_handler led:14
问题还没解决，那位大虾救救啊

Answer 1

TCNT1H = (65535-31250)/10;
TCNT1L = (65535-31250)%10;
时间错误；
