目标电压detectedTarget设备ID（0x0）是无效的设备ID

大家晚上好。我知道这已经被问过很多次了，但是我检查了论坛里所有的ANSER，我仍然无法解决这个问题。好的部分是，我已经知道所有的问题，你可以问我，所以我会尝试回答他们之前。我有：-原始的PACtiT3-MPLAB X（最后版本V4.05）- MaOS SieRa。-我正在尝试编程的微是DSSPICEP32 MC202。我得到的错误是：连接到MPLAB皮卡3…当前加载的固件在PoxIT 3固件套件版本…05.1.06固件类型….DSPIC3E/24ETARGET电压检测目标设备ID（0x0）是无效的设备ID。请检查您与目标设备的连接。连接：这是DSPIC上的连接。VSS和接地符号是相同的，这是我用的硬电源。有了固定增益，我创造了一个稳定的3.3伏从更高的电压。即使在负载（微）的情况下，电压也不会下降。电阻器和电容器的值取自数据表、“推荐的最小连接”和“电路串行编程”（IPSP）考虑。一个万用表每一个连接的连续性-尝试两个DSPIC（它们都是全新的，昨天从MSOER到达）-我用短电缆从皮卡到面包板。-PGED和PGEC没有附加任何其他组件。-我尝试了每一个PGEDX/PGECX（1,2,3）在MICRO-。AB X IDE和MPLAB IPE。两者都给了我同样的错误。-我试图摆脱我自制的电源和：-切换选择PICTIT3提供电路的供应。-使用来自ARDUINO的3.3个输出来提供电路。-我尝试改变目标设备以强制更新PICTIT3上的固件，然后再次切换到正确的设备，以强制再次更新固件，并使用正确的一个。-我检查了我使用的最后版本。两个MPLAB IDE和IPE。-直到2天前，皮卡用PIC18工作得很好，现在我不想再试了。我只有我正在工作的DSPIC。用安培表我看到DSPIC从电源上拿了4Ma（带和不带PICTIT3）。-这很奇怪，但我在尝试一切。因为我这里没有任何逻辑分析仪/示波器，所以我试着把一个LED连接到PGD管脚上，这样LED就不会闪闪发光。如果相反，我试图强制连接到PIC（我强迫MPLAB继续错误）LED闪闪，然后再次抛出错误。我删除了后来的LED，因为我知道PGED工作良好，如果没有附加到线。-我探查了MCLR引脚，它下降到投掷错误之前。当编程时，它不应该达到高于3.3的电压吗？-我不能肯定PGED和PGEC之间没有交叉对话，但我猜没有这样的串扰，因为相同长度的相同的线被用来成功地编程PIC18。你可以看到，我尝试了关于这个问题的其他帖子的所有建议。你能给我点别的东西试试吗？我订购了一些电压调节器有一个更严重的电压源，因为我坚信，这个问题依赖于电流/电压，我提供给微。当我在编程PIC18时，我可以使用一个专业的电源（那些是盒子大小的，可以输出不同电压范围的），现在我还没有得到它。感谢所有的建议，问候，弗朗西斯科。



      以下为原文

    Good evening everybody. I know this has been asked a milion of times, but I checked all the ansers in the forum and still I can't resolve the issue. The good part is that I already know all the questions that you could ask me so I'll try to answer them before.

What I have is:

- original picKit3
- MPLAB X (last version v4.05)
- macOS Sierra.
- The micro I am trying to program is dsPIC33EP32MC202.

The error that I get is:

Connecting to MPLAB PICkit 3...
Currently loaded firmware on PICkit 3
Firmware Suite Version.....01.51.06
Firmware type..............dsPIC33E/24E

Target voltage detectedTarget Device ID (0x0) is an Invalid Device ID. Please check your connections to the Target Device.

Connections:

This are the connections on the dsPIC. Vss and the ground symbol are to be considered the same.

This is what I used for a stiff power supply. With a fixed gain I create a stable 3.3 Volts from a higher voltage. The voltage doesn't drop even with the load (the micro) attached.


The values for resistors and capacitors are taken from the datasheet, section "recommended minimum connections" and from "In-Circuit Serial Programming™ (ICSP™) Considerations".

What I did trying to solve the problem:

- I checked with a multimeter the continuity of each connection.
- Tried two dsPIC (they are both brand new, arrived from mouser yesterday).
- I use short cables from the pickit to the breadboard.
- PGED and PGEC haven't any other component attached.
- I tried every PGEDX/PGECX (1,2,3) on the micro.
- I used both MPLAB X IDE and MPLAB IPE. Both give me the same error.
- I tried to get rid of my home made power supply and:
    - Toggle the option of the pickit3 to provide the supply to the circuit.
    - Used the 3.3 output from an Arduino to supply the circuit.
- I tried to change the target device to force an update on the firmware on the pickit3 and then switch again to the correct device to force again the update on the firmware with the correct one.
- I checked that I was using the last version of both MPLAB IDE and IPE.
- Untill 2 days ago the pickit was working perfectly fine with a PIC18, now I don't have it to try again. I only have the dsPIC I am working on.
- Using a amperometer I saw that the dsPIC is taking 4mA from the supply (with and without the pickit3 connected).
- This is strange, but I was trying everything. Since I don't have any logic analyzer/oscilloscope here, I tried to attach just for one time an LED to the PGED pin and it seems that the LED doesn't flash before trowing the error. If instead I try to force the connection to the pic (I force MPLAB to continue after the error) the LED flashed before throwing an error again. I removed the LED afterwards since I know that PGED works well if nothing is attached to the line.
- I probed the MCLR pin and it goes low before throwing the error. Shouldn't it go to a voltage higher than 3.3 when programming?
- I can't be sure that there is no cross talking between PGED and PGEC, but my guess is that there isn't such crosstalking since the same wires with the same length were used to program succesfully the PIC18.

As you can see, I tried all the suggestions on the other posts regarding this issue. May you enlight me on something else to try? I ordered some voltage regulator to have a more serious voltage source, since I am strongly convinced that the problem relies in the current/voltage that I am supplying to the micro. When I was programming the PIC18 I had access to a professional power supply (the ones that are a box size and can output different ranges of voltage), now I haven't access to it.

Thanks to all for the suggestions,
regards, Francesco.
