I have the PICkit plugged straight into the board, no extension cable.

I didn't notice it yesterday, but when I press the connect button to connect to the programmer, it gives me this error:

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

I tried pressing on the picket to try to get good connections on the programming headers but that didn't do anything.

I'll inspect my solder joints. It looks to me like it is a straight shot from the programming header to the dsPIC. Doesn't seem like a whole lot to go wrong.

I don't need the peripherals like throttle or encoder connected for programming, do I? the only connections I have to the board are power from a DC 24v supply, and the PICkit3.

I don't remember that error. I'll try my board tonight ... since it is not inside a car right now

I don't remember having any peripherals connected when I'm programming.

I don't really want to re-program my board, but I think I can go through the motions and tell it not to program at the end.

I may turn on the phone and record what I do so that I will remember next time I hope it happens tonight ... but it may be sometime during the weekend.

I do remember that every time I have verified the program between chip and hex file it has failed. That had me confused for a long time.

Here's the video, which is just pictures with a voice-over. It's my old laptop so the capture software does not really work, and the flickering of video from a laptop screen is horrid.

Hope this helps

Thanks for the video. It helps to see what is supposed to happen

I installed version 2.3 like you just to eliminate the newer version I was using as a variable. Still no change.

Attached is a photo of what happens when I try to connect.

I think I'm going to try soldering thin wires directly to the dsPIC from some .1" headers to connect directly to the PICkit3. It seems to me like a connection issue, and I'm running out of ideas...

I find it unlikely that Digikey would sell me counterfeit or faulty chips, especially on two occasions.

I've got a chevy volt controller working well. It's 2 separate controllers inside. so, this is a perfect cotroller for load testing 2 nissan leaf motors connected together, having their torques battle it out. Here's the setup. Almost ready to test:

Is the Nissan Leaf motor Induction or BLDC?

Sorry if you mentioned it in the video, couldn't watch it with sound at work

Did you design a logic board for the Volt inverter Paul?
