单片机C程序问题

Posted 2023-03-13

#include<reg52.h>
#define uchar unsigned char
#define uint unsignes int

sbit led=P1^0;
sbit key=P3^0;

unsigned char code smg_du[]=0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90

void delay_50us(uint t)

uchar j;
for(;t>0;t--)

for(j=19;j>0;j--);



void main()

uchar num;
while(1)

if(key==0)

delay_50us(200);
if(key==0)

num++;
led=0;
if(num==10) num=0;
while(!key);
delay_50us(200);
while(!key);


else
led=1;
P0=smg_du(num);



错哪了？偶是初学的，请哪位高手帮忙下，，，
加上分号后keill3提示有以下错误：
DJ.C(10):error c141:syntax error near 'int',expexted ')'
DJ.C(13):error c202:'t';underfined identifier
DJ.C(39):error c211;call not to afunction
DJ.C(39):error c208:'function:too many actual parameters

第10句：void delay(uint t)
第13句：for(t;t>0;t--)
第39句：P0=smg_du(num);

问题1：#define uint unsignes int笔误吧，应该是：#define uint unsigned int
问题2：少分号，上面的已经说了；
问题3：P0=smg_du(num)应该是：P0=smg_du[num]; 参考技术A unsigned char code smg_du[]=0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90;

少了个分号,其它好像无错哇~~~ 参考技术B #define uint unsignes int

拼写错误 是 unsigned

unsigned char code smg_du[]=0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90 少个分号
