EXPLORER 8支持PIC16F15356 MCU吗

首先，我不拥有一个Explorer 8板，但是，1）产品页面描述了8位PIC微控制器兼容所有PIC MCUS8，14，20，28，40/44，64和80引脚脚，因此PIC16F15356应该适合，因为它是一个8位28引脚。但是检查示意图和PIC管脚不会是错误的。（2）MPLAX和XC8，也许MCC，PIC由McC3支持）用于编程微控制器，你将需要一个像ICD 3，真正的ICE或皮卡3这样的程序员。



      以下为原文

    First of all, I don't own an Explorer 8 Board,
 
but,
1) Product Page says for 8-bit PIC microcontrollers 

• Compatibility with all PIC MCUs
  
• 8-, 14-, 20-, 28-, 40/44-, 64- and 80-pin footprints
  

so the PIC16F15356 should fit because it's an 8-bit with 28 pins. But checking the schematic and the PIC-pins wouldn't be wrong to be on the save side.
 
2) MPLAB X and XC8, perhaps MCC, that PIC is supported by MCC
3) For programming the Microcontroller you will need a programmer like ICD 3, REAL ICE or PICkit 3

嗨，1，因为有各种类型的套接字/PIMS，探险家8应该能够容纳几乎任何PIC16或PIC18设备。2/MPLAB X，XC8和I强烈建议您使用MCC插件来创建项目。需要一个外部程序员：PICTIT3或ICD4（ICD4已经取代ICD3）问候



      以下为原文

    Hi,
1/ As there are various types of sockets / PIMs, the EXPLORER8 should be able to accomodate almost any PIC16 or PIC18 device.
2/ MPLAB X,  XC8 and I strongly recommend that you use MCC plugin to create projects.
To get started, look for tutorials here : http://www.microchipdeveloper.com
3/ You will need an external programmer : Pickit3 or ICD4 (ICD4 has replaced ICD3)
Regards
 

谢谢你们的宝贵意见，我会做所有的事情。随着PIC我被留下，我必须恢复。我有一个辉煌的MPLAB ICE 2000不同PCM，所以我必须更新我的开发系统从经济卡开始，然后我会购买更复杂和专业的系统。



      以下为原文

    Thank you all for your valuable advice, I will do them all.
With the pic I was left behind and I have to recover.
I have a glorious MPLAB ice 2000 with different PCM so I have to renew my development systems starting with economic cards, then I will buy more complex and professional systems.

如果你只需要开发简单的应用程序，我建议购买好奇心开发板。它是廉价的，它包括一个集成的程序员/调试器，并且不需要额外的硬件来启动。它们也在特殊状态直到28 FEB 2018。



      以下为原文

    IF you just need to develop simple applications, I would recommend to buy the Curiosity development boards. It's cheap and it includes an integrated programmer/debugger, and requires no additional hardware to get started.
They are also on special till 28 Feb 2018.

Excel 8在好奇心板上的主要优点是它有很多内置接口：LCD显示、UART I/F、许多LED /按钮、电位器。好奇心板一般都有一个LED和1/2个按钮。如果你瞄准一个28/40引脚设备，那么好奇HPC可能是另一种选择（没有）。外部的PACKIT3，因为它有一个板上的程序员/调试器



      以下为原文

    Hi
The main advantage of EXPLORER8 over curiosity boards is that it has lots of built-in interfaces :
LCD display, UART i/F, many leds / buttons, potentiometer.
Curiosity boards generall have one led and 1/2 pushbuttons.
If you target a 28/40 pins device, then curiosity HPC could be an alternative (no external pickit3 necessary as it has an on-board programmer/debugger) 
Regards
 

我现在购买了Explorer 8，感谢所有有价值的信息。一旦我收到卡片，我就开始实验，我一定会再次需要你的帮助。皮耶罗



      以下为原文

    I bought now Explorer 8, thanks to all for the valuable information.
As soon as I receive the card I start the experiments, I will surely need your help again.

之前我买了一个Explorer 8卡，现在我等待着到来。我正在检查各种可能性，我遇到的第一个问题如下：我必须使用一个20 MHz或更多的石英，因为我需要产生一个12.288 MHz的时钟发送到DSP，这是该项目的一部分硬。“我不想用2的石英”。我在探险家8上看到的石英是8兆赫，但是在与探险家8有关的各种PDF中，没有材料清单，因此我看不到石英的类型，用来购买同一尺寸的布局，但频率不同。有人能告诉我吗？找8号探索者的材料清单？或者，有人可以告诉我，如果在PIC16F15356上使用内部时钟，就有可能在输出引脚上产生12.288 MHz的频率。



      以下为原文

    As written before I bought an explorer 8 card and now I await the arrival.

I am examining the various possibilities and the first problem I encounter is the following.
I have to use a 20 MHz or more quartz because I need to generate a 12.288 MHz clock to send to a DSP that is part of the project hardware, "I do not want to use 2 quartz".
 
 
I saw the Quartz on the explorer 8 is 8 MHz, but in the various PDFs related to Explorer 8 there is no bill of material and therefore I can not see the type of quartz used to buy one of the same size of layout but with different frequency.
 
Can anyone tell me where to find the Explorer 8 Bill of material?
 
Alternatively, someone can tell me if on the PIC16F15356 using the internal clock there is the possibility of generating a frequency of 12.288 MHz on an output pin.
Thanks in advance

总是读取数据表或用户指南来获取这些信息。在用户指南中，有一个组件列表的电路图。在数据表时钟源类型的第9.2节中：高频内部振荡器（HFIFOTSC）可以产生一个从1到32 MHz的范围。在输出引脚上产生12.288 MHz的频率是什么意思？



      以下为原文

    Always read the datasheet/ or user's guide to get these kind of information. In the user's guide there is a circuit diagram with the list of components.
In section 9.2 of datasheet Clock Source Types: The High-Frequency Internal Oscillator (HFINTOSC) can produce a range from 1 to 32 MHz.
What do you mean by generating a frequency of 12.288 MHz on an output pin?

这个指南我下载了它，但是不同于HTTP：//WW1.Microchip .com……ViceDoc／EVB2250BOM.PDForExplorer 8，这是不存在的。如果要替换8 MHz的石英，如果有组件建造者的描述的材料清单，我检查了石英布局，我可以IMM。在不等待探险者8看到石英的物理尺寸的情况下，买一个不同的。为了产生一个12.288 MHz的频率，我打算把MCU的内部时钟除以一个输出引脚上的12.288 MHz的时钟。



      以下为原文

    This guide I downloaded it but unlike what happens for example:
http://ww1.microchip.com/...vicedoc/evb2250bom.pdf
for explorer 8 this does not exist.
Having to replace the 8 MHz quartz if there was a bill of material with the component builder's description I checked the quartz layout and I could immediately buy a different one without waiting for the Explorer 8 to see the physical dimensions of the quartz.
To generate a frequency of 12.288 MHz I intend to divide the internal clock of the MCU to have a clock at 12.288 MHz on an out pin

我不知道你打算如何产生这个12.288兆赫的信号，但是这个PIC（16F15356）有一个NCO外设，你可以用来产生许多不同的频率信号。如果你在PIC中使用8 MHz XTAL和4XPLL，那么你将拥有一个32 MHz的系统时钟。然后NCO将能够在大约30 Hz到32 MHz（包括12.2879兆赫和NCO的增量计数为402653）的宽范围的频率上产生信号。希望这有帮助。



      以下为原文

    I do not know how you intend to generate this 12.288 Mhz signal however this pic (16F15356) has an NCO peripheral which you could use to generate many different frequency signals. If you use the 8 Mhz XTAL and the 4xPLL in the pic then you would have a 32 Mhz system clock. The NCO will then be capable of generating signals over a wide range of frequencies from about 30 hz to 32 Mhz (including 12.2879 Mhz with an increment count of 402653 for the NCO). Hope this helps.

在一个MCU的PIN上生成一个1288MHz时钟是我必须要做的事情。& Br／& Gt；如果我理解的是正确的，我可以分配给PATA或POC的任何引脚“NCO1OUT”作为附加的图像& lt；IMG SRC=“HTTP://www. miPrimoOVDAME.COM/TIME/1.JPG”ALT=“//gt；& lt；IMG SRC=”“HTTP://www. miPROMUVODOMANE”。COM/TEMP/ 2。JPG“ALT=”“/ & gt；& lt；/p & gt；

请记住，NCO的输出将具有显著的抖动，特别是在较高的频率。这是一个纯粹的数字设备，所以输出时钟边缘对齐参考时钟边缘（32兆赫）。



      以下为原文

    Keep in mind that the output of the NCO will have significant jitter, especially at higher frequencies. It's a purely digital device, so output clock edges are aligned to the reference clock edges (32MHz).

叹息…我已经经历过这样的事情，一次或三次。还有一点比NCO插入一个增量值要多。这里的协议……源时钟为32兆赫，NCO当然可以产生一个平均频率为12.2879 MHz的信号，但是由于NCO的DDS性质，NCO源的一个周期会有抖动。E时钟。换句话说，平均周期将是大约80纳秒，但抖动将是大约30纳秒。而且，这不是一个更短或更长的周期。抖动频率是输出频率的可观分数。我不能想象这将是有用的采样时钟的DSP（或任何其他类型的“时钟”）。（作为对感兴趣的读者的练习：做数学）另一个现实生活细节中的那些讨厌的现实：即使是很轻的负载（“范围探测”），假设抖动是可以接受的，PPS输出引脚在12 MHz时不会给出干净的信号。这些东西不具备高速数字输出的驱动能力。我停止了“范围”，并用我的PIC16F15355在32 MHz的NCOCON＝805306下运行了附加的范围拍摄，这样你们就可以看到我在说什么了。（注意，对于方波输出，切换频率必须是方波频率的2倍）。底线：我认为从PIC期待一个有用的12.288 MHz时钟输出是不合理的。[编辑]当我进行范围拍摄时，MBRUBULIN把我和我正在制作的点（+ 1）打得一模一样。我仍然希望这是值得的带宽来显示他正在谈论什么，以及实际的局限性，产生一个时钟信号，这是一个可观的分数输入时钟与NCO。只是不实用（没有一吨的外部过滤，在这种情况下，它比使用一个真正的时钟生成器更昂贵）。（编辑）问候，戴夫



      以下为原文

   
Sigh...
I've been through this kind of thing a time or three.  And there's a little more to it than just plugging an increment value into the NCO.
 
Here's the deal...
 
With a source clock of 32 MHz, the NCO can certainly generate a signal with average frequency 12.2879 MHz, but due to the DDS nature of the NCO, there will be a jitter of one period of the NCO source clock.  In other words, the average period will be around 80 ns, but the jitter will be about 30 ns.  And, this isn't a shorter or longer period every now and then.  The jitter frequency is an appreciable fraction of the output frequency.  I can't imagine this would be useful as a sample clock for DSP (or any other kind of "clock").  (Left as an exercise for the interested reader: Do the math.)
 
Another one of those little nasty-realities-of-real-life details: Even with a very light load ('scope probe), and assuming the jitter would be acceptable, the PPS output pins will not give a clean signal at 12 MHz.  These things just doesn't have the drive capability for high-speed digital outputs.
 
I stopped the 'scope and took the attached 'scope shot with my PIC16F15355 running at 32 MHz with NCOINC = 805306 so you can see what I'm talking about.  (Note that for square wave output, the toggle frequency must be 2x the square wave frequency.)
 
 
Bottom line: I don't think it's reasonable to expect a usable 12.288 Mhz clock output from the PIC.
 
[Edit]
While I was taking the scope shot, mbrowning beat me to the punch with the point I'm making  (+1).  I still hope it's worth the bandwidth to show what he is talking about, and the practical limitations of generating a clock signal that is an appreciable fraction of the input clock with the NCO.  Just not practical (without a ton of external filtering, in which case, it's more expensive than just using a real clock generator).
[/Edit]

谢谢你的回答，我做了一些假设，因为我还没有今天才购买的Explorer 8，所以我没有进行任何实际的测试。从你给的亲切的回答中，最好的是使用石英作为DSP，并留下所有逻辑部分、按钮、Outp的管理。UT位、转换器等到MCU。



      以下为原文

    Thanks for the answers
I'm making some assumptions because I do not have yet Explorer 8 purchased only today, so I have not carried out any practical test.
From the kind answers you gave you, the best thing is to use a quartz for the DSP and leave the management of all the logical part, buttons, output bits, converters, etc. to the MCU.

虽然我当然同意所有关于NCO输出信号特性的信息，但我只是想说明一种可能产生信号的方法。因为OP并没有真正描述这个12.288 MHz信号的用途，也不知道这个信号的规格是什么，所以很难说什么将“工作”什么也不会。我不知道一个更好的方法与特定的PIC提到产生一个输出信号的规定频率，将有更好的抖动规格。有什么建议吗？



      以下为原文

    While I certainly agree with all the information about the characteristics of an NCO output signal I was simply trying to illustrate one possible method to produce a signal. Because the OP does not really describe what the use of this 12.288 Mhz signal is nor what the specifications of this signal need to be it is difficult to say what will "work" and what will not. I do not know of a better method with the specific pic mentioned to produce an output signal of the stated frequency that will have any better jitter specs. Any suggestions?

12.288 MHz的时钟必须发送到DSP的MCLKI上，在DSP上OSCO引脚将被打开。然而，如果NCO输出具有如此高的抖动，那么将石英连接到DSP是很方便的。



      以下为原文

    The clock at 12.288 Mhz must be sent to MCLKI of a DSP, on the DSP the OSCO pin would be left open.
However, if the NCO output has such a high jitter it is convenient to connect a quartz to the DSP

你可以让PIC在你想要的频率下产生精确的时钟输出，但是你必须相应地选择PIC的晶体。



      以下为原文

    You can have the PIC generate a precise clock output at the frequency you want, but you will have to choose the PIC's crystal accordingly.

16F15356具有20 MHz的外部晶体操作的上限（32 MHz与外部振荡器），因此它似乎是唯一可能的外部XTAL导致12.288 MHz输出信号将是12.288 MHz，然后将振荡器（FoSC）信号直接输出到参考时钟输出。



      以下为原文

   
The 16F15356 has an upper bound of 20 Mhz for external crystal operation (32 Mhz with external oscillator) so it would seem the only possible external xtal to result in a 12.288 Mhz output signal would be 12.288 Mhz and then feed the oscillator (Fosc) signal directly out the Reference Clock output.
