KEY.C(1): error C129: missing ';' before 'digbit'
上面是我在编译程序时的一个错误提示,但我不明白它是什么意思.程序是一个电子密码锁的一个程序,但无法进行编译,望各位前辈指点一二,谢谢.

要在最前面加这个

#define uchar unsigned char

turmary你好,我加上去以后,问题更多了,提示如下

你缺少定义P1,P2的头文件了.比如如果是89C51要加#include <reg51.h>
还有你明显没定义scaccode这个变量

你看不是少了“；”？还是不细心，都告诉你了C129: missing ';' before 'digbit'（129行，digbit前面丢失“；”），安一个金山词霸吧

只看该作者 · 2007-5-6 17:17

首先谢谢各位前辈的指点,但是我加上头文件也不能编译,还是一样的提示,我在P0后面加上一个;号后,提示一样,不知道是那里的问题望各位前辈再指点一下,各位前辈那里有没有能编译调试过的程序,发给我看一下好吗,看看在我这能调吗谢谢

只看该作者 · 2007-5-6 17:24

那里有一长段I2C从机的程序，肯定能编译的，只不过在效果上不太好

天隼之翼你那贴子从那里进入呢

这个问题跟软件有关吗,我换了好多程序都不能运行,请前辈多多指点,谢谢

看你的P好像是小写的
c语言区分大小写吧

这句没有加“；”。
