报错：Error[Pe020]: identifier “s” is undefined看上图，s肯定是已经定义了，为什么还会有这种报错。请小伙伴注意，如果这是c文件中声明的第一个函数，那么肯定是头文件出问题了。我这边回头查看头文件，没有报错。但是发现函数后面少了一个分号。加上去后解决了。...

错误信息：error: #40: expected an identifier原因1：是命名重叠了, 比如在stm32f10x.h中有如下定义typedef enum {ERROR = 0

已经包含了pic.h我看了下pic.h，里面是#if defined(_16F873)|| defined(_16F874)||\ defined(_16F876)|| defined(_16F877)||\ defined(_16F872)|| defined(_16F871)||\ defined(_16F870)#include然后查看，里面有：/*bank 1 registers */static unsigned char bank1OPTION@ 0x81;static volatileunsigned char bank1TRISA@ 0x85;static volatileunsigned char bank1TRISB@ 0x86;也就是应该有这个option寄存器了，然后我又试了下在程序里添加#include ，结果是 D:\program\main.c; 2.21 can't open include file "pic1687x.h": No such file or directory求教大神
