大家好，请帮助/建议我关于ICD3调试器与目标板的连接。我有一个定制的目标板，具有PIC32 MX350F256L控制器，并使用MPLA X IDE V4.01。我使用MPLAB ICD3进行编程/调试。我已经收到了RJ11电缆和ICD3。但是我的目标板上没有RJ11。因此，我没有使用切割电缆，而是使用了一个相同的电缆，它具有相同的引脚和相同的长度以连接目标板。但是，当我试图调试项目时，我得到的错误是“没有找到目标设备（无法检测到目标电压VDD）。你必须连接到一个目标设备使用ICD3。“但是实际上我已经连接了我的目标板和另一个电源。并对电缆线路的连续性进行了测试。仍然存在上述错误。我不能连接到目标板。请帮助我配置ICD3调试器与目标板连接。

You must connect to a target device to use ICD3." but actually i have connected my target board with another power supply. and also tested the continuity in cable lines. still getting above mentioned error. and i'm not be able connect to target board. please help me to configure ICD3 debugger to connect with target board. regards Krishna

“无法检测目标电压VDD”，它没有看到您的VDD。重新检查你的连接。
以上来自于百度翻译 以下为原文 "could not detect target voltage VDD" It does not see your Vdd. Recheck your connections. |

ICD3电缆改变每一端的编号。一端的1和6，在另一端是6和1，我猜你们的电线是从哪里反射出来的。
以上来自于百度翻译 以下为原文 ICD3 cabling changes numbering at each end. 1 -> 6 at one end is 6 -> 1 at the other end. My guess is you have the wires mirrored from where they should be. |

你应该从ICD3上为你的板供电吗？在这种情况下，您需要检查ICD3选项“来自ICD 3的电源目标电路”。/ Ruben
以上来自于百度翻译 以下为原文 Are you supposed to power your board from the ICD3? In that case you need to check the ICD3 option "Power target circuit from ICD 3". /Ruben Attached Image(s) |

谢谢你的回复……正如你提到的，我已经验证了连接，并且检查了我使用的电缆的连续性，即RJ11电缆。对我来说，它看起来很好。我已经为目标板提供了5V电源，这不是来自ICD3。这一次，我得到了上面提到的错误。“你应该从ICD3上为你的板供电吗？”在这种情况下，你需要检查ICD3选项“来自ICD 3的电源目标电路”。当我从ICD 3选择电源目标电路而不从目标板提供电源时，上述错误不会出现，并给出“目标未被检测到”的错误。“我的问题是，如果我从ICD3和P中选择两个电源，即从ICD 3选择的电源目标电路。RovidIn 5V供电目标板（为板板供电）将导致一个问题，因为提供两个电源。？？？斯克里希纳
以上来自于百度翻译 以下为原文 thanks for reply.... as you mentioned i have verified the connections and checked the continuity also for the cable which i'm using i.e. RJ11 cable. for me it looks good only. and i have powered the target board with 5v supply which is not from the ICD3. that time i'm getting the above mentioned error. ''Are you supposed to power your board from the ICD3? In that case you need to check the ICD3 option "Power target circuit from ICD 3". '' when i'm selecting the Power target circuit from ICD 3 and not providing power supply from target board, the above error is not coming and giving error as ''Target is not detected.'' here my question is if i select both power supplies i.e. Power target circuit from ICD 3 which i select from ICD3 and providing 5v supply target board (for traget board power supply) will it cause a problem because of providing both power supplies. ??

你读过我的文章了吗？您确定没有反向连接吗？地面在中间，所以它可以，但VDD和MCLR将与编程引脚交换，如果你有，这将给出确切的效果，你描述。
以上来自于百度翻译 以下为原文 Have you read my post above? Are you sure you have not reversed the connection? Ground is in the middle, so it will be ok, but VDD and MCLR will be swapped with the programming pins if you have, which will give exactly the effect you describe. |

如果你想确定的话。设置冰为目标，让我们说4伏特。测量并看4伏是否属于它。还要检查ICD连接器上的吊舱。坏电话插座会损坏它们。你有一个正确的6x6电话插头的电缆吗？
以上来自于百度翻译 以下为原文 If you want to be sure. Set the ice to power the target at lets say 4 volts. Measure and see if the 4 volts is where it belongs. Also inspect the pod on the ICD connector. Bad phone jacks can damage them. And you have a cable with the correct 6x6 phone plug? |

谢谢大家的帮助。正如你所说的，我交换了PIN（即我连接了6 -＆1在目标板），它开始工作。
以上来自于百度翻译 以下为原文 thank you guys for helping. as you said, i swapped the pins (i.e. i connected 6-->1 on target board) and it started working. Thanks & Regards Krishna. |

你好，MMK47 1，你解决了“目标设备没有发现（无法检测到目标电压VDD））。你必须连接到一个目标设备来使用皮卡3。“如果是的话，请告诉我你是如何解决这个问题的，因为我有同样的问题要花我一个星期。非常感谢。罗伯特。”
以上来自于百度翻译 以下为原文 Hi MMK471, Did you solve"Target device was not found (could not detect target voltage VDD). You must connect to a target device to use PICkit 3.". IF YES, tell me how did you solve thsi issue, please, because I have the same issue broth me one week. Thanks a lot. Robert |

他把后3号标记为“最佳答案”，所以这可能是固定的。如果你得到这个消息，PK3就不会从你的板上看到任何电压，所以你的连接不好。
以上来自于百度翻译 以下为原文 He marked post#3 as "Best answer", so that was probably what fixed it. If you get that message, the PK3 is not seeing any voltage from your board, so you have a bad connection. |

大家好，这个问题已经按照MysIL＆Qub＆Du0000 001的建议进行了修改。非常感谢。罗伯特
以上来自于百度翻译 以下为原文 Hi All, This issue already fixed by following the suggestions of Mysil & qub & du00000001. Thanks a lot. Robert |
