接触CY不久，现在准备做低功耗，想问下摸索过程中碰到的问题

Wireless-Tech

系统进入深度睡眠后，采用一个外部中断引脚唤醒。
执行完PIN中断函数之后，系统就莫名其妙不工作了，Debug停在下面这段代码

void CySysPmSleep(void)
{
    uint8 interruptState;

    interruptState = CyEnterCriticalSection();

    /* CPU enters Sleep mode upon execution of WFI */
    CY_PM_CPU_SCR_REG &= (uint32) (~CY_PM_CPU_SCR_SLEEPDEEP);

    /* Sleep and wait for interrupt */
    CY_PM_WFI;

    CyExitCriticalSection(interruptState);
}

主程序中下面这句BLE事件处理是灰色的。不知道什么鬼，代码中有将BLE进入低功耗模式CyBle_EnterLPM(CYBLE_BLESS_DEEPSLEEP)。

void RunBle()
{
    CyBle_ProcessEvents();
}

1、你如果是要测试低功耗就不要用Debug，因为Debug下MCU是不会真正进入睡眠状态的
2、这个只是检查消息队列有没有消息，有就处理，没有就不处理
3、从你给出的信息中，我看不到你的问题出现在哪里

Wireless-Tech

是这么回事，我换了个方法测试，我的GPIO中断程序执行完之后，我的BLE没有按照我希望的方式去工作，即使我在中断函数里重新打开BLE

Wireless-Tech

你能否把你的Main函数截个图给我看看吗？

int main()
{
    /* Enable global interrupts */
    CyGlobalIntEnable;

    /* Internal low power oscillator is stopped as it is not used in this project */
    CySysClkIloStop();

    /* Set the divider for ECO, ECO will be used as source when IMO is switched off to save power */
    CySysClkWriteEcoDiv(CY_SYS_CLK_ECO_DIV8);

   SystemInit();

    /* Start CYBLE component and register the generic event handler */
    apiResult = CyBle_Start(AppCallBack);

    /* Wait for BLE Component to Initialize */
    while (CyBle_GetState() == CYBLE_STATE_INITIALIZING)
    {
        CyBle_ProcessEvents(); 
    }

    applicationPower = ACTIVE;

    /*If DEEPSLEEP_ONLY is enabled, then the device stays in deep sleep all the time  
    * This is a good way to check if there are any leakage currents in the device. */
    #if DEEPSLEEP_ONLY
    CySysClkEcoStop();    
    CySysPmDeepSleep();
    while(1);
    #endif    

    /***************************************************************************
    * Main polling loop
    ***************************************************************************/
    while(1)
    {
        /***********************************************************************
        *  Process all BLE events in the stack
        ***********************************************************************/
            RunBle();

        /***********************************************************************
        *  Put BLE sub system in DeepSleep mode when it is idle
        ***********************************************************************/ 
        ManageBlePower();

        /***********************************************************************
        *  Run your application specific code here
        ***********************************************************************/  
        if(applicationPower == ACTIVE && 0 == bFlag_BrushMachine)
        {
            RunApplication();
        }

        /***********************************************************************
        *  Manage power modes for application specific components 
        ***********************************************************************/
        ManageApplicationPower();   

        /***********************************************************************
        *  Manage system power mode based on application and BLE power modes
        ***********************************************************************/
        ManageSystemPower();
    }
}

我是在例程上修改的，就在RunApplication()这个前面多加了个判断条件，还有我自己的硬件初始化

Wireless-Tech

Wireless-Tech
1、你硬件初始化不会是放在RunApplication()吧？
2、你之前现在是想要实现什么样的功能？

Wireless-Tech

找到问题了,多添加的判断在其他地方被置1了，初始化时放在这里的SystemInit();
