Question

求帮助，单片机程序调试出现这样问题.c(13): error C129: missing ';' before 'code'

#include<reg52.h>
#include "DELAY.H"
#include "1602.h"
sbit rs=P2^0;
sbit rw=P2^1;
sbit e=P2^2;
uchar code tab1[]={"20 - - "};
uchar code tab2[]={" : : "};
void write_com(uchar com)
{
e=0;
rs=0;
rw=0;
P0=com;
delay_50ms(10);
e=1;
delay_50ms(20);
e=0;
}
void write_data(uchar dat)
{
e=0;
rs=1;
rw=0;
P0=dat;
delay_50ms(10);
e=1;
delay_50ms(20);
e=0;
}
void shianbase()
{
uchar a;
write_com(0x80+1);
for(a=0;a<14;a++)
{
write_data(tab1\[a\]);
delay_50ms(1);
}
write_com(0x80+0x40+2);
for(a=0;a<8;a++)
{
write_data(tab2\[a\]);
delay_50ms(1);
}
}
void lcd_init()
{
write_com(0x38);
write_com(0x0c);
write_com(0x06);
write_com(0x01);
}
2.c(7): error C129: missing ';' before 'code'出现是这个

Answer 1

修改如下：
#include<reg52.h>
#include "DELAY.H"
#include "1602.h"
sbit rs=P2^0;
sbit rw=P2^1;
sbit e=P2^2;
uchar code tab1[]="20 - - ";
uchar code tab2[]=" : : ";
......

Answer 2

你没有定义#define uchar unsigned char

Answer 3

keil本身是没有 uchar这个类型的 只有unsigned char

添加个预定义 #defined uchar unsigned char
让编译器遇到uchar 就用unsigned char 替换 就不会报错了

在#include "1602.h"的下面添加
#defined uchar unsigned char
