调试软件时点击暂停按钮就不会显示程序lo是怎么回事？

最新的MPLAB X版本，在V3.40？我正在用一个现实调试OK



      以下为原文

    latest MPLAB X version  as in V3.40?
 
Mine is Debugging OK with a RealICE

是的V3.40忘记添加它。很奇怪，我不能无缘无故地调试。我的应用程序没问题，没有任何异常。我从未经历过这样的问题



      以下为原文

    Yes v3.40 forgot to add it. It's very strange I can't debug for no reason. My application is ok, there aren't any exceptions. I've never experienced something like this issue

这与真正的ICEIt是MplabX或编译器无关。除非您的代码有bug并已逸出，否则不会。您能调试吗？如果你只是在调试器中点击运行，它会起作用吗？你有例外处理程序吗？



      以下为原文

    That is Not an issue with the Real ICE
It is MplabX or the Compiler.
Unless your code has a bug and has run away, then it is not.
Can you debug at all?
If you just hit run in the debugger does it work?
 
Do you Have exception Handlers?

编辑：我确实有一堆



      以下为原文

    EDIT: I DO have a heap

构建过程除了生成程序集指令之外，还生成调试信息，该调试信息解释如何将特定地址的单个程序集指令映射到原始源文件中的代码行。MPLAB X使用这些信息将当前PIC设备PC映射到源代码中的一行代码。上面的消息表示MPLAB X无法将当前PIC PC映射到源代码中的一行代码。通常这种情况发生是因为当前的PC实际上没有映射到源代码行。例如，PC可能处于库例程的中间。或者你的程序可能跳错了，并且正在执行随机的存储器位置。你总是可以使用Windows->PIC内存视图->Program Memory来确切地看到PC在哪里以及正在执行什么操作码。



      以下为原文

   
 
The build process, in addition to generating the assembly instructions, also generates debug information that explains how to map individual assembly instructions at specific addresses to source lines of code in your original source files.  MPLAB X uses this information to map the current PIC device PC to a line of code in your source.
 
The message above is saying that MPLAB X is unable to map the current PIC PC to a line of code in your source.  Usually this happens because the current PC doesn't actually map to a line of source code.  For example, the PC may be in the middle of a library routine.  Or your program may have made a bad jump and is executing random memory locations. 
 
You can always use the Window -> PIC Memory Views -> Program Memory to see exactly where the PC is and what opcodes are being executed.
