我的理解是变量声明与函数正篇的分离可该报错还是报错啊

首先句尾分号没加语法错误，其次没太看懂这一句是表达什么意思 pch是uchar指针，ACII_TAB明明是uchar却拿来当数组名跟括号

顺便建议看下项目文件结构，别人怎么写的，一个include头文件解决的不用全部extern一大堆，还有extern一般是指明函数的定义在其他的文件，这里根本不需要。

ASCII_TAB那句是指向字符起始列的点阵码教科书上写的还有如果不extern就会报错一堆说我没声明变量笑cry

你确认自己代码没错？你的代码里面extern指明的ACSII_TAB根本不是数组地址，还有不是你加了extern不报错就说明这样写很对
我还是那个建议，好好看看别人代码include咋写的。。。不是杠你，可以给你写代码省很多力气。。要不你就一天到晚研究这个那个变量报错没声明吧

ID:207421 · 发表于 2021-3-25 15:00

1. I2C.c 里面Stop(),调用时用的stop()
2. LCD12864IO.c 里面ASCII_TAB，LCD_WrDat，LCD_WrCmd, CS1等根本不知从哪里冒来的
3. 自动打铃系统.c 里面ISendStr,IRcvStr,LCD_DispIni,LCD_DispFill,LCD_DispHZ,LCD_DispHZStr这些函数根本不存在，for(no=0,no<4;no++)还写错了
4. 应该学习一下框架式编程
5. 网上拷贝拼凑的代码吧？不然很多函数没有，怎么连自己都不知道

错误太多：主要是抄写错误，错用大小写等等。
给你改了，对比一下就知道哪里错了。

您好新帖里的新代码已经补上所有缺的东西了请问P_CS1的P的意思是？

在c语言中不能有两个同名变量

前面 sbit CS1=P1^2; 已经有一个CS1，所以这里 #define P_CS1 0 不能有相同的
