设置振荡器，像这样，首先做一个简单的LED测试，以确保系统运行。然后我认为你需要在睡眠功能被调用之前设置一些东西。像这样，Microchip代码配置器（MCC）是值得学习使用的，如果你长期使用它。它将产生振荡器和其他位的代码。



      以下为原文

    Setup the oscillator, Like this
 

 // NOSC HFINTOSC; NDIV 4;
 OSCCON1 = 0x62;
 // CSWHOLD may proceed; SOSCPWR Low power; SOSCBE crystal oscillator;
 OSCCON3 = 0x00;
 // LFOEN disabled; ADOEN disabled; SOSCEN disabled; EXTOEN disabled; HFOEN disabled;
 OSCEN = 0x00;
 // HFFRQ 1_MHz;
 OSCFRQ = 0x00;
 // HFTUN 0;
 OSCTUNE = 0x00;


Then do a simple LED test first, to make sure the system is running. Then i think you need to set somethings before the sleep function is called. Like this
 

VREGCON = 0b11; //lowest power mode but slowest wake up time
IDLEN =0; //when set to 0, SLEEP() causes full pwr down mode. 1 = idle mode

 
The Microchip Code Configurator (MCC) is worthwhile learning to use, if you are in it for the long run. It will generate the code for the oscillator and other bits.

    Hello,
The PIC I'm using has three power off modes: DOZE mode, IDLE mode, and standby mode (P113). I would like using the button to vary these three modes by an interruption.

On my test plate, I put a push button connected to RC5 (at rest 5V on RC5 and if a press on the BP, 0V on RC5), I thus wish to use the interrupts and the different mode of consumption of the mode sleep of my PIC16F18345
1 / BP at rest-> no interruption on RC5-> PIC in SLEEP mode
2 / Press BP-> interrupt on RC5-> PIC in DOZE mode -> Program in operation
3 / RE Press BP-> interrupt on RC5-> stop program-> PIC in IDLE Mode

My current code does the following thing: power on -> sleep mode, press the button -> normal mode
I can not vary the different modes. Thank you in advance ![quote=brownt]// CONFIG1

P 113 to 118--> power-saving operation modes
 

你是说你的代码现在起作用了。你可以用按钮按压唤醒睡眠模式，然后移动到正常操作？我不知道为什么你做了下面的两个步骤，但是不管怎样，IOC被启用是不被检查的，而你需要检查中断标志IOCDFBIT.IOCFCF5在中断中，清除它，然后运行你的代码。



      以下为原文

    are you saying that your code now works. In that you can wake it from sleep mode with a button press, and it moves to normal operation?
 
I am not sure why you have done the following twice
 

 
if(PIE0bits.IOCIE)
 

 
But regardless, the IOC being enabled is not to be checked, rather you need to check for the interrupt flag IOCDFbits.IOCCF5 within the interrupt, clear it, and then run your code.

我的程序不正常工作，我不能停止在第二次按下返回正常模式



      以下为原文

    My program is not working properly I can not stop at the second press to return to normal mode

第一台新闻是怎么做的？你能确认设备处于休眠状态吗？是否正在检查IOC标志？



      以下为原文

    What does the first press do?
 
Can you confirm that the device is in sleep mode?
 
Is the IOC flag being checked?

在上电时，μC直接进入休眠模式。当我第一次按下时，它进入正常模式。



      以下为原文

    On power up, the μc goes directly into sleep mode. When I press a first time, it goes into normal mode.

请问CIO是什么？



      以下为原文

    What's CIO please ?
 

CIO，我不明白你的意思。你是说国际奥委会吗？按下按钮时，中断例程将运行。在例行程序中，应该检查IOC标志，如果它被设置，那么你就知道按钮被按下了。然后清除标志并运行代码，直到再次按下按钮。



      以下为原文

    CIO, I don't know what you mean. Do you mean IOC?
 
When the button is pressed the interrupt routine will run. Within the routine the IOC flag should be checked, if it is set, then you know the button has been pressed. You then clear the flag and run your code, until the button is pressed again.

变更的中断——



      以下为原文

    Interrupt On Change --> P.173

为什么两次？但不管怎样，它不是IICIE你想检查，它是IOCIF，中断标志。您要检查是否已经设置了标志，因为在按下按钮时将设置标志。检查是否设置了标志，清除标志，然后运行代码，直到再次按下按钮。



      以下为原文

    why PIE0bits.IOCIE twice?
 

if(PIE0bits.IOCIE) // IT changement d'etat bouton
    {
   CPUDOZEbits.IDLEN = 1;
    IOCCFbits.IOCCF5 = 0; // RAZ flag IT
   }
   else if (PIE0bits.IOCIE){
     CPUDOZEbits.DOZEN = 1;
     IOCCFbits.IOCCF5 = 0; // RAZ flag IT
  }

 
but anyway, it is not IOCIE that you want to check, it is IOCIF, the interrupt flag. You want to check if the flag has been set because the flag will be set when the button is pressed. You check if the flag is set, clear the flag, and run your code until the button is pressed again.

我现在不能改变模式，当我按按钮时什么也没发生。



      以下为原文

     


I can not change the mode now, when I press the button nothing happens





 
 
void interrupt ISR ()
{
if(IOCCFbits.IOCCF5 == 1) // IT changement d'etat bouton
{
CPUDOZEbits.IDLEN = 1;
IOCCFbits.IOCCF5 = 0; // RAZ flag IT

}

}

这里有一些建议HTTP://PcPosial.RIC323……PIC.PHP？F＝11和t＝649



      以下为原文

    Hi
 
Made some suggestions here http://picforum.ric323.co...pic.php?f=11&t=649

你如何确定系统处于正常模式？你可以像这样测试中断。你可能会有一些开关跳动，但是你应该看到一些事情正在发生。



      以下为原文

    how are you determining that the system is in normal mode?
 
You could test the interrupt like this. You might get some switch bouncing, but you should see something happening.
 

void interrupt ISR ()
{
     if(IOCCFbits.IOCCF5 == 1) // IT changement d'etat bouton
    {
       //LED = !LED; Each time BP is pressed the LED will change. Or measure with meter or oscilloscope

       IOCCFbits.IOCCF5 = 0; // RAZ flag IT
   }
 
}
