怎么在PICKIT2中选择电压

你没有提到，但我认为你没有任何权力的目标，必须提供电源从PK2。这是真的吗？如果你必须从PK2提供电源，你有没有试着在“5”伏特设置旁边标记“ON”的复选框？你的目标需要多少电流？PK2只能提供约30Ma。



      以下为原文

    You don't mention, but I assume you don't have any power on the target, and must supply power from the PK2.
Is that true?
 
If you have to supply power from the PK2, have you tried ticking the checkbox labelled "on" next to the "5.0" volt setting?
How much current does your target require? The PK2 can only supply about 30mA.
 

是的，我正在使用皮卡的电源。我们应该用外部电源来代替PACTIT2的电源吗？



      以下为原文

    Yes i'm using power supply from the pickit.
Shall we use external power supply instead power supply from pickit2....?

是的，试着在外部给你的电路板供电，并将PK2设置为“力目标”或“自动检测”。



      以下为原文

   
Yes, try powering your board externally, and set the PK2 for "Force target" or "Auto detect".

水晶和所有其他电路都与控制器相连，通过使用PGC、PGC PIN……



      以下为原文

    What happen crystal and all other circuits are connected with controller and by using board power to dumb the code controller by using PGC,PGC pins..?

我不明白你的问题是什么，所有这些项目都是通电的，不管电源来自哪里，除非你已经采取特殊的措施来隔离PIC VDD与你的板的其余部分。我想你说“哑巴代码”，你的意思是“转储代码”，这有很大的不同。在“B”和“P”之间的那个词（和“烧伤”将是一个更好的词比“转储”无论如何）。



      以下为原文

    I do not understand what your question is.
All those items are powered up, regardless of where the power is coming from, unless you have taken special measures to isolate the PIC VDD from the rest of your board.
I think then you say "dumb the code", you meant "dump the code".
There's a big difference between "b" and "p" in that word (and "burn" would be a better word than "dump" anyway).
 

在连接拾取设备工作之前，请查找附件图像文件，但当将PICTIT2连接到连接器故障时，请参阅电路图以供参考。



      以下为原文

    Please find the attached image files,
Before connecting the PICKIT it working fine but when connecting the PICKIT2 to the connector its malfunctioning.
Please refer the circuit diagram for reference.

嗨，什么故障？什么工作良好？我们不知道你在说什么。当你没有准确地解释你在做什么时，没有什么是显而易见的！一个皮卡2不可能提供足够的电流来正确地为LCD背光提供电源。使用皮卡2设置来自动检测目标功率，如果电路板有电源，不要尝试强制拾取器2供电。在第三图像中的消息1中，PIDIT 2程序员应用程序显示连接的MIC。ROPCORE是PIC16F628 A，5伏电源接通，闪存擦除已完成。注意，通过USB电缆提供的电压2作为电压测量的参考，所以如果USB电压低，则显示的电压可能会误导。窗口：[]/MCLR是控制PICIT连接器PN1上的复位信号。迈西尔

    Hi,
What is malfunctioning? And what is working fine?
We do not know what you are not telling. Nothing is obvious when you do not explain precisely what you are doing!
 
A PICkit 2 is Not likely to be able to supply enough current to properly power LCD Backlight. 
Use PICkit 2 setting to auto-detect Target power,
Do Not try to Force PICkit 2 to supply Power, if the board have power.
 
In the 3.rd image in message #1,
PICkit 2 programmer application show that connected microcontroller is PIC16F628A,
that 5 V power is on, and that Flash memory Erase have been completed.
 
Note, that PICkit 2 use voltage supplied thru USB cable as reference for voltage measurements,
so if USB voltage is low, then voltage displayed may be misleading.
 
The second checkbox in Programmer application window: []  /MCLR , is to control the Reset signal on pin1 of PICkit  connector.
