Question

我是新来的。我正在使用Microchip的XC8编译器和PIC18F25K22。当我构建代码时，我收到错误

>>> "ABChi hi".count("hi")
2
>>>

如果我注释掉这个代码行，我收到下一个寄存器命令的错误（在我的情况下：SSP1CON1） - 我尝试了包括xc.h 和htc.h但也有同样的错误。

我在stackoverflow中发现了一个类似的问题，但问题是通过将这些命令放在一个函数中来解决的，但是我的函数在函数中。

这是我的代码：

xc8.exe --pass1 --errformat="Error at file %%f line %%l column %%c: (%%n) %%s" --warnformat="Warning at file %%f line %%l column %%c: (%%n) %%s" --msgformat="Message at file %%f line %%l column %%c: (%%n) %%s" -G --chip=18F25K22  -O"main.p1" "../main.c"

所有注册声明（SSP1CON1，TRISCbits等都在xc.h中声明（并且它的嵌套包含）。您的问题可能是i2c.h包含引用了xc.h

中显示的定义

尝试撤消您的包含的顺序，以便在您自己（或第三方）包含之前将系统包含在内。

一般情况下，您应始终将所有系统包含（即文件用<>指定的那些）放在您自己的（包含＆＃34;＆＃34;）之后。

寄存器的XC8冲突声明（例如TRIS，SSP1CON1，......）
