PIC16LF18325可以使用Timer1从打盹睡眠模式唤醒吗？

检查数据表的第9部分，讨论瞌睡模式。如果设置正确，一个启用源的中断会唤醒CPU的瞌睡（请再次参阅数据表）。外围设备，包括Time1，继续在瞌睡模式下运行。



      以下为原文

    Check section 9 of the datasheet, it discusses DOZE mode. An interrupt from an enabled source will wake the CPU from DOZE if the settings are correct (see data sheet again). The peripherals, including timer1, continue to operate in DOZE mode.

你好！我发现了我的错误！我已经设置了Ty0CON1寄存器，而不是T1CON寄存器。现在我的代码工作如预期。我必须注意到，使用16MHz的系统时钟，以FoSC／4为内部时钟的最大Time1周期IGET和1:8的预分频器（大约）131Ms。我希望PIC从瞌睡睡眠模式E唤醒。2秒。所以我要么使系统时钟1MHz，要么使用来自实时时钟设备DS323的32 kHz时钟信号，并将其设置为T1CON寄存器。如果我去第二个解决方案，我如何注入一个32 kHz的时钟刺激？我知道我必须做一些刺激。谢谢。



      以下为原文

    Hi!
I have spotted my mistake!
I had set the T0CON1 register instead of the T1CON register.
Now my code works as expected.
 
I have to note thogh that using a 16MHz system clock the maximum timer1 period I
get with Fosc/4 as the internal clock and the prescaler as 1:8 is (roughly) 131ms.
 
I want the PIC to wake up from Doze Sleep mode every 2 seconds.
 
So I either make the system clock 1MHz or I use the 32KHz clock signal from
the Real Time Clock device DS3231 with the appropriate settings to T1CON register.
 
If I go for the second solutions how do I inject a clock stimulus of 32KHz?
I know I have to do something in Stimulus.
 
thanks

您可以更改时钟的Time1到LFIFTSC（31千赫），并获得更长的延迟。这个OSC在瞌睡期间工作。



      以下为原文

    You can change the clock for timer1 to the LFINTOSC (31khz) and get longer delays. This osc operates during DOZE.

嗨，我已经改变了Time1到LimtoSc（13kHz）的时钟源，PIC并没有从睡眠中醒来。它应该每2秒醒来一次。有什么想法吗？



      以下为原文

    Hi.
I have changed the clock source for timer1 to LFINTOSC (31KHz).
MOVLW B'11000101'
    MOVWF T1CON
 
PIC doesn't wake up from sleep. It was supposed to wake up every 2 seconds.
Any thoughts?

只在瞌睡模式下工作，你确定你不是在使用睡眠吗？



      以下为原文

    Only works in DOZE mode, are you sure you are not using SLEEP instead?

Ok. So this is my code.

您的代码是启用空闲模式不瞌睡模式：您必须设置十二位在CPUDOZE，以使瞌睡模式。然而，Time1中断仍然应该唤醒PIC在任一模式（虽然不是在睡觉）。你怎么知道PIC没有醒来？我看不到代码中使用什么作为唤醒的指示器。



      以下为原文

    Your code is enabling the IDLE mode NOT DOZE mode:
BSF CPUDOZE, IDLEN
You must set the DOZEN bit in CPUDOZE to enable DOZE mode. However the timer1 interrupt should still wake the pic in either mode (not in SLEEP though). 
How do you know the pic doesn't wake up? I see nothing in your code to use as an indicator that wake-up has occurred.

你可以使用WDT从睡眠中醒来。这不是很准确。



      以下为原文

    You can use the WDT to wake up from sleep.  It is just not very accurate.

我用模拟器作为调试工具。我只是在设备进入空闲模式之后运行仿真，等到Time1中断发生后，在中断程序中执行恢复。在中断例程中，我放置了一个断点。因此，如果发生了Time1中断，那么中断执行程序中的代码执行应该停止，但这永远不会发生。我已经设定了一次每秒中断一次。



      以下为原文

   
 
Well I am using the Simulator as the debugg tool. I just run the simulation after device has enter idle mode
and wait till execution resumes in interrupt routine after the timer1 interrupt occurs. In interrupt routine I have placed a breakpoint. So code execution should stop in interrupt service routine if a Timer1 interrupt has occured.
But this never happens. I have set the timer1 to interrupt every 2sec.

最新消息：我已经在MULL中添加了下面的代码。ASMI已经使用ICD3和UPM2编程了PIC设备，并且我可以看到UPM2的LED（连接到RC2引脚）每2秒切换一次！所以Time1在我的代码中实现了它！那么为什么不能在模拟器模式下工作呢？我必须使用刺激和弹出时钟信号或其他东西吗？亚历山大

I have programmed the pic device using ICD3 and UPM2
and I can see the led of UPM2 (connected to RC2 pin) toggle every 2 seconds!
So timer1 works the way I have implemented it in my code!
 
So why doesn't work out in Simulator mode?
Do I have to use the stimulus and eject a clock signal or something else?
 
Alexandros

Asfar，我可以看到你从来没有启用中断与GIE位。



      以下为原文

    Asfar as I can see you never enable the interrupts with the GIE bit.

如果你指的是iToCon寄存器的GIT位，那么我就设置它。



      以下为原文

   
If you mean the GIE bit of INTOCON register then I do set it.
Have a better look at io.asm file I am displaying in previous post.

是的，对不起，我错过了。我通常不使用二进制数来设置SFR，通常使用来自Inc/h文件的位字段名称，使读取这些内容变得容易得多。



      以下为原文

    Yep, sorry I missed that. I do not normally use binary numbers to set SFRs, usually use the bit field names from the inc/h files, makes reading these things so much easier.

我想知道这是否是模拟器问题，因此把这个问题转移到Simulor论坛。



      以下为原文

    I was wondering if this is a Simulator issue and therefore transfer this issue to the
Simulator forum

当然可以，我很少使用模拟器，他们可能会麻烦太多的时间。

    Certainly could be, I seldom use simulators, they can be troublesome too much of the time.
