用了iccavr 和 atmel studio 写了同样的代码编译..


// 595 operation
#define PORT_595_CLK  PORTB
#define PORT_595_DAT  PORTA
#define DAT_595    0
#define SHCLK    0
#define STCLK    1
#define CLR_595_ST()  PORT_595_CLK &= ~(1<<STCLK)
#define SET_595_ST()  PORT_595_CLK |= (1<<STCLK)
#define CLR_595_DAT()  PORT_595_DAT &= ~(1<<DAT_595)
#define SET_595_DAT()  PORT_595_DAT |= (1<<DAT_595)
#define CLR_595_SH()  PORT_595_CLK &= ~(1<<SHCLK)
#define SET_595_SH()  PORT_595_CLK |= (1<<SHCLK)
#define SEND_TO_595(word) do
       {
        CLR_595_ST();
        for(char i=0 ; i<8 ; i++)
        {
         CLR_595_SH();
         if ((word) & (1<<(7-i)))
         {
          SET_595_DAT();
         }
         else
         {
          CLR_595_DAT();
         }
         SET_595_SH();
        }
        SET_595_ST();
       } while (0)
//segment LED operation
#define SEGLED_CLR()  PORTD |= 0xf0
#define SEGLED_SET(i)  PORTD &= ~(1<<(7-i))
#define SEGLED_CODE(word) SEND_TO_595(word)
   
//display data
unsigned char led_code[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71} ;
unsigned char dis_buff[] = {0,0,0,0};
unsigned char clock[] = {0,0};

ISR(TIMER0_COMP_vect)
{
static unsigned char disIndex = 0;
unsigned char dis_data;
dis_data = led_code[dis_buff[disIndex]];
SEGLED_CLR();
SEGLED_CODE(dis_data);
SEGLED_SET(disIndex);
++disIndex;
if (disIndex >4)
{
  disIndex = 0;
}
}

在iccavr上面只是把那个ISR改了..
结果iccavr是对的..
as确实错的.. iccavr

附图是as编译结果的运行..
iccavr是实现动态扫描


二楼附上as编译出来的汇编

as编译结果运行.. as编译结果运行..
