使用PICU唤醒如何工作

如果你打开冬眠。C（ISR文件）&；Wakeup，C文件，你可以发现，在中断服务程序中部分“flag_hibernate”被设置为分别为1和0。
所有的事情，你复制粘贴到另一个项目是什么？如果我们能调试一下这个新项目，那就更好了。

     以下为原文
  If you open Hibernate.c (ISR file) & Wakeup.c files, you can find that in the Interrupt Service Routine section "FLAG_HIBERNATE" is being set to 1 and 0 respectively.
     
    What are all the things you copy pasted into another project? It would be better if we could debug the new project.

关于CY8CKIT-1001和CY8CKIT-014的开关配置之间的差异问题，是的，它们都是不同的。
在CY8CKIT-1001中，如果您按下开关，引脚将连接到地上。所以我们需要在内部拉动。在CY8CKIT-014，如果您按下开关，引脚将连接到VDD（3.3V）。所以我们需要在内部把它拉下来。
如果将GPIOS的配置更改为下拉，则应该工作。

  Regarding your question on difference between Switch configurations of CY8CKIT-001 & CY8CKIT-014, yes they both are different.
     
    In CY8CKIT-001, if you press the switch, Pin will be connected to Ground. So we need to pull it up internally. In CY8CKIT-014, if you press the switch, Pin will be connected to Vdd (3.3V). So we need to pull it down internally.
     
    If you change the configuration of the GPIOs to Pull downs, it should work.

你好，基肖尔，
非常感谢你的帮助。我知道有一些中断的配置我错过了，现在我看到它在哪里。以前，我只复制了.Me.c文件和TopDebug .CysCH中的所有内容；我没有想到组件在他们的.c文件中可能有有用的配置。现在我在我的程序的Hibernate .c和唤醒.c文件中有相关的代码，它就像这个例子一样工作。
现在有一个后续问题：
在我看来，这样做的方法是：当任何一个引脚都有中断的电压时，就会发生两件事。第一局唤醒从休眠（如果是在Hibernate）下，相应的hibernate_interrupt函数运行。这似乎是因为董事会是在休眠模式，并按与Hibernate中断相关的按钮，会被唤醒了，flag_hibernate整数集（再次）1。它贯穿于项目的while循环，一旦进入如果（flag_hibernate）分支，将自己睡了。
那么，首先，我在那个假设下是正确的吗？其次，它是可能的配置板，只有特定的中断引脚将它从冬眠中醒来？
至于我的其他问题了，谢谢你的解释，在过去的几天我做了一点研究，如何将这些按钮实际上是工作，所以你的答案有道理，这些关系是很有帮助的。

   Hello Kishore,
    Thank you very much for your help. I KNEW there was some sort of interrupt configuration I was missing, and now I see where it is. Before, I had only copied over the main.c file and everything in the TopDesign.cysch; I hadn't thought that components could have useful configurations in their .c files. Now that I have the relevant code in my program's Hibernate.c and Wakeup.c files, it's working just like the example.
    Now here's a follow-up question:
    It looks to me like the way this works is:
when there's a voltage on either of the pins configured for interrupts, TWO THINGS HAPPEN. First the board wakes up from hibernate (if it was in hibernate) and next, the corresponding Hibernate_Interrupt function runs. This seems right because when the board is in hibernate mode, and you press the button associated with the Hibernate interrupt, the board gets woken up and the FLAG_HIBERNATE integer is set (again) to 1. It runs through the program's while loop once and enters the if (FLAG_HIBERNATE) branch and puts itself to sleep again.
    So first of all, am I correct in that assumption? And second of all, is it possible to configure the board such that only CERTAIN interrupt pins will wake it from hibernate?
     
    As for my other question, thank you for your explanation -- in the past couple days I've done a bit of research as to how these buttons are actually working, so your answers make sense, and those links were quite helpful.

嗨，杰夫，
这个项目有2个中断。一个将PSoC置于休眠状态，另一个用于唤醒。
在与Hibernate关联的ISR中，在中断时旗标HiberHibernate被设置为1。
在与Wakeup相关联的ISR中，在中断时将旗标FigHiHiBiNATE重置（设置为0）。
中断设置为下降沿。这是因为引脚被设置为电阻拔起，默认情况下会很高。当开关被按下时，引脚连接到接地，因此检测到下降沿（从高到低）。如果按下Hibernate引脚，则ISR中的标志设置为1，导致设备将休眠。这是在C。当设备已经处于休眠状态时，如果再次按下Hibernate PIN，则标志仍然设置为1，因此LED将只切换一次，然后返回休眠。
要唤醒PSoC，唤醒引脚必须被按下。这将重置标志，设备将处于活动模式，直到再次按下Hibernate引脚。
在第一触控套件中，将“中断类型”设置为“下降沿”和“驱动模式”为“电阻下拉”。
您可以通过配置PSoC中的“任意”PIN来从Hibernate唤醒系统。也有睡眠模式，这将唤醒从几个其他来源除了PICU类似于从地址匹配在I2C，睡眠定时器等。

  Hi Jeff,
     
    There are 2 interrupts used in the project. One to put the PSoC to Hibernate, and the other for Wakeup.
    In the ISR associated with Hibernate, the flag FLAG_HIBERNATE is set to 1 upon interrupt.
    In the ISR associated with Wakeup, the flag FLAG_HIBERNATE is reset (set to 0) upon interrupt.
     
    The interrupts are set to falling edge. This is because the pins are set to Resistive pull up and will be High by default. When the switch is pressed, the pin is connected to ground, hence there is a falling edge detected (from high to low). The flag is set to 1 in ISR if Hibernate pin is pressed, resulting in the device going to hibernate. This is done in the main.c .  When the device is already in hibernate, if Hibernate pin is pressed again, the flag is still set to 1, hence the LED will toggle only once and then go back to hibernate.
    To wake up the PSoC, the Wakeup pin must be pressed. This will reset the flag and the device will be in active mode till the hibernate pin is pressed again.
    In First touch kit, set the "Interrupt type" in the Pin configuration box to "falling edge" and the "Drive Mode" to "Resistive pull down".
     
    You can use PICU by configuring "any" pin available in PSoC to wake up the system from hibernate. There is Sleep mode available too which will wake up from several other sources apart from PICU like Slave Address match in I2C, Sleep Timer, etc.
