MCU在断点处停止

你好
 
 
 ''我尝试调试我的应用程序，但是当我使用断点或破坏应用程序执行时我遇到问题，因为MCU在断点处停止。例如，如果我使用输出PWM，我会在示波器上看到PWM，直到我中断执行，当我从当前语句执行时我再次看到它。
 当我打破应用程序执行时，如何将其更改为不停止MCU？''
 
 我想你错过了解。断点是停止处理器执行。
 
 ''当我打破应用程序执行时，如何将其更改为不停止MCU？''
 你不能。断点的全部原因是停止并检查处理器正在做什么。
 
 如果你想不停地调试，'检测代码'
 例如
 将printf放入（如果你有支持，例如通过串口）
 在代码中的某些点切换备用IOport引脚。

Hi


''I try to DEBUG my application but I have a problem when I use breakpoint or break the application execution because the MCU stop when it is on the breakpoint. For example, if I use output PWM, I see PWM on oscilloscope until I break the execution and I see it again when I execute from the current statement.
How can I change it to don't stop the MCU when I break the application execution ?''

I think you miss-understand. The point of a break point is to stop the processor executing.

''How can I change it to don't stop the MCU when I break the application execution ?''
You cannot. The whole reason for a break point is to stop and examine what the processor is doing.

If you want to debug without stopping, 'instrument the code'  
eg
Put printf in (if you have support for it eg through serial port)
Toggle spare IOport pin at certain points in the code.

不要使用断点。它们用于停止执行，因此您可以检查寄存器和行。
 
 通常我使用调试引脚来捕获输出信号状态，或者安装无限等待循环。循环的问题是，如果仍然启用中断（定时器等），它们仍将处于活动状态，因此可能会改变您的状态。

Don't use a breakpoint.  They are used to stop execution so you can examine registers and lines.

Often I use either a debug pin to capture output signals states, or install an infinite wait loop.  The problem with the loop is that if interrupts are still enabled (timers and such), they will still be active so may change things on you.
