Question

我用keil软件编译的时候出现问题，大家请帮忙啊………应该不是程序长度的限制

Build target 'Target 1'
assembling a.asm...
A51 MACRO ASSEMBLER V8.00d - SN: Eval Version

程序如下：
#include <AT89X52.H>

unsigned char code dispbit[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};

unsigned char code dispcode[]={0x3f,0x06,0x5b,0x4f,0x66,

0x6d,0x7d,0x07,0x7f,0x6f,0x00,0x40};

unsigned char dispbuf[8]={0,0,0,0,0,0,10,10};

unsigned char temp[8];

unsigned char dispcount;

unsigned char T0count;

unsigned char timecount;

bit flag;

unsigned long x;

void main(void)

{

unsigned char i;

TMOD=0x15;

TH0=0;

TL0=0;

TH1=(65536-4000)/256;

TL1=(65536-4000)%256;

TR1=1;

TR0=1;

ET0=1;

ET1=1;

EA=1;

while(1)

{

if(flag==1)

{

flag=0;

x=T0count*65536+TH0*256+TL0;

for(i=0;i<8;i++)

{

temp[i]=0;

}

i=0;

while(x/10)

{

temp[i]=x%10;

x=x/10;

i++;

}

temp[i]=x;

for(i=0;i<6;i++)

{

dispbuf[i]=temp[i];

}

timecount=0;

T0count=0;

TH0=0;

TL0=0;

TR0=1;

}

}

}

void t0(void) interrupt 1 using 0

{

T0count++;

}

void t1(void) interrupt 3 using 0

{

TH1=(65536-4000)/256;

TL1=(65536-4000)%256;

timecount++;

if(timecount==250)

{

TR0=0;

timecount=0;

flag=1;

}

P0=dispcode[dispbuf[dispcount]];

P2=dispbit[dispcount];

dispcount++;

if(dispcount==8)

{

dispcount=0;

}

}

你这个项目建立的时候有问题
Build target 'Target 1'
assembling a.asm...

他编译的是a.asm文件
我不知道你是不是不上面的代码 保存为a.asm
如果是就改成a.c 吧

如果是.a 或者.asm文件..编译器会默认调用 汇编器编译的.当然会有问题
