#0楼

以前都用汇编,C语言没弄过.

完全照书上的二个C语言例子,编译没通过.不知道错在哪里,请求帮助.谢谢

第一个程序：

#include

#define uchar unsigned char

#define uint unsigned int

uchar code SEG7[10]={0xc0,0xf9,0xa4,

0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,}

void delay(uint k)

{

uint i,j

for(i=0;i

for(j=0;j<121;j++)

{;}}

}

void main(void)

{

uchar m=0,n=0

P0=SEG7[n]

P1=SEG7[m]

delay(3000)

P0=0xff

P1=0xff

P2=0xff

{

uchar m=8,x=6

P0=SEG7[n]

P1=SEG7[m]

P2=SEG7[x]

delay(3000)

P0=0xff

P1=0xff

P2=0xff

}

P0=SEG7[n]

P1=SEG7[m]

delay(3000)

while(1)

}

第二个程序：

#include          /*item 1*/

void msec(unsigned int);   /*item 2*/

void main(  )

{

unsigned  char array[10]

unsigned char i;

while(1)                   /*item 3*/

{

for(i=0;i<=9;i++)          /*item 4*/

{

array[i]=P2=P0        /*单片机的C语言应用程序设计P89*/

msec(100)

}

}

}

void msec(unsigned int x){

unsigned char j;

while ((x--)! =0){

for(j=0,j<125;j++)

{;}

}

}
