PIN自定义名称的含义是

定义了RC4xToGeLe[（）d{LabcTys.LATC4= LATCITS.LATC4；}（0）可以用：*定义：RC4Twitter TrcBITS.LATC4^＝1 / /独占ORC44Twitter；//CAPS，因此您知道它是宏而不是变量或函数。你为什么把它们放进去？



      以下为原文

    #define RC4_Toggle() do { LATCbits.LATC4 = ~LATCbits.LATC4; } while(0)
 
You can replace with:
#define RC4_TOGGLE LATCbits.LATC4 ^= 1  //exclusive or
 
RC4_TOGGLE;   //caps so you know that it is a macro rather than a variable or function.
 
Take out all the do..whiles.  Why do you put them in?

他问为什么“定制的名字”没有被使用。他没有。是MCC把它们放在那里。这是我在别处看到的一些C技巧，以确保宏中的所有语句都被当作一个单独的块。



      以下为原文

    He is asking why the "Custom name" is not being used.
 

He didn't. It was MCC that put them there.
This is some C trick I've seen elsewhere to ensure all statements in the macro are treated as a single block.
 
 

如果您右键单击RC4YTwitter；或者在代码中的任何地方，选择“导航”，然后单击“查看宏扩展”，您将看到代码将在编译之前查看。



      以下为原文

    If you right click RC4_TOGGLE; or anywhere in your code, select, "navigate" and then click, "view macro expansion" you will see the code as it will look before it is compiled.
 
 

你会以为用1条单行线是没有理由的。我不使用MCC，认为这是你编写的代码。看起来还行。



      以下为原文

    You would have thought that with 1 single line there would be no reason for it.
 
I don't use MCC, thought it was code that you had written.
 
Looks ok.
 

可能是某个块像下面这样，所以“通用宏”（RC4**（））仍然可用，只是使用它们的“自定义名称”变体。您可能需要搜索这些-它们可以在MCC生成的标题中的任何地方。P.S.：我不经常使用MCC，但我做同样的事情。手工操作。



      以下为原文

    Could be somewhere is a block like the following #define PWR_STATUS_SetHigh()   RC4_SetHigh()
#define PWR_STATUS_SetLow()   RC4_SetLow()
Thus the "generic macros" ( RC4_*() ) are still available, the "Custom name" variants just using them.
You might have to search for these - they could be anywhere in the MCC-generated headers.

P.S.: I do not use MCC routinely, but I do the very same thing manually.

嗨，In MCC，如果在“PIN模块”或其他设置窗口中发生了什么变化，则需要点击“资源管理”中的“生成”按钮，在左上面板中，改变在头文件或代码中生效。}当（0）围绕宏时，在GCC文档中解释：http://gcc.gun.org/OnLeNeDoCs/CPP/吞并分号。



      以下为原文

    Hi,
In MCC, if something is changed in 'Pin Module', or other setup windows,
then it is needed to click the 'Generate' button in 'Resource Management', in the upper left panel, for the change to take effect in header files or code.
 
The construct that is used by MCC:    do { ... } while(0)
around a macro, is explained in GCC documentation:

不要用下划线和大写字母或另一个下划线来使用名称。它们是严格保留的，供编译器使用。这是大多数C编译器的一般规则。



      以下为原文

    Do NOT use names starting with an underscore followed by either an upper-case letter, or another underscore.
They are strictly reserved for use by the compiler.
That is a general rule in most C compilers.
