单片机语法编译错误

㈠ 单片机C语言 keil编译这些错误怎么改

前面定义的全局变量数组wenzi[]最后应该是分号，而不是逗号。

延时子程序中用了库函数_nop_();必须用#include包含头文件intrins.h。因为没加头文件，_nop_()是不识别的，才引起变量p错误。

两个延时子程序前面要加void，否则编译时会警告。

主程序中还有几处错误，修改如下图

㈡ 单片机程序编译的时候出错了，要看的只有三条语句。

前面那个是赋值运算，P3 ^ 4就是P3的值和4做异或运算，结果是一个常数，给常数赋值当然是错误的；
后面那句是判等，P3 ^ 0 == 1等同于P3 ^（0==1）就是P3的值和0做异或运算，再判断结果是否为真，这样的运算是符合规定的，所以不会报错，只是结果不是你想象的了

㈢ pic单片机编译经常出现的错误有哪些

编译器只能识别语法错误，没办法判断那种单片机会错误，那种单片机不会错。编译出现的错误，只能归结为
LZ
的
C语言水平不够，或者
打字不够细心。
但PIC
单片机使用的
注意点倒是不少，最让人
闹心的就是，PIC
默认打开
AD
功能，要想把引脚当
普通
IO
使用，必须
自行关闭
AD功能。很多初学者，连IO操作都没开始，就必须先操作特殊功能了，你说闹不闹心。
另外，PIC的
硬件堆栈也是个注意点，低级（便宜）的型号，硬件堆栈可能只有
2~3层，高级（贵货）的可以达到16层，普通型号也有7~8层了。这玩意是用来计算“函数
调用
函数
调用
函数”的层数的，主函数算0，主函数开始调用的功能子函数算1，功能子函数调用的驱动子函数算2……

㈣ 单片机编译时出现错误

A51中$可以调用一些指定的控制指令，例如文件的调用$include (c8051f040.inc)
$NOMOD51；使A51汇编器预定义的SFR无效等
当$后面跟的指令错误或无效时。就会出现这种错误提示。

XREF Primary Includes the cross-reference table in the listing file.

㈤ 这个单片机程序老是提示语法错误，该怎么处理

这程序不是你自己写的吧，大括号用的太乱了，好多地方不成对；你把各个函数都划分开，仔细排查一下；我实在看得眼花；

㈥ 紧急请教各位高手关于51单片机编译出错的问题

A9--错误是语法错误。因为你的LOOP后面的：不是英文状态的，还有下面的DELAY,D1,D2后面的。
A3--错误是字符没有定义，去掉后面的分号；--这不是C语言。好用P10改为P1.0--中间的.也是英文的，语句中间的逗号，也要改为英文的。改掉这些就可以通过了。我编译通过。

㈧ 单片机c语言用keil编译时出现如下的错误是什么原因'=':illegal type conversion from/to 'void'，急求

Write_24C02 ();
下方错误提示显示的是，这个函数返回类型是 void 也就是没有设定返回值，所以使用 = 等号 就产生了语法错误。

㈨ 如图，请问单片机这样编程提示错误，哪里语法错误了

第一个错误是 DEC 未定义，
此外100行花括号不匹配，后面还有多处花括号不匹配。
写程序要注意书写规范，要不然就是自找麻烦…

㈩ 单片机编程时为什么总出现syntax error

这个东西可能是你的编译程序没安装好，或者是你在编译时开了多个文本程序，导致编译不出，系统报错
