Re: Need Help: Test Spinning Prius motors with FOC firmware [SOLVED]

Eons later I have returned to this problem and solved it. I did Damien’s resolver test he outlines in his FOC tuning video, and I also realized that I had a value of 10500 for syncoffs, which was good enough to keep my motor from spinning.

Hello everyone, I am looking to see if anyone is interested in building out/programming an V1d board for me for paid support.

Re: Chevy Volt Gen 2 charger 24281923

I am not sure…
Mine has less markings on the AC connector than it did on the DC one, just says “DELPHI”
But I have not spent much time looking for it yet.

I have found that this connector works for the HV DC output on the charger: https://www.digikey.com/en/products/det ... -1/5423199
and this one for the control pins: https://www.digikey.com/en/products/det ... 01/1756779

Thank you both! unfortunately I've been away from my testing set up, but will be back Tuesday and will be making updates to my parameters/troubleshooting per your advice, and getting new resolver plots.

Ah Shoot, dumb mistake! I was looking at the pinout description on the gen3 board wiki, forgot about the separate schematic for the dual motor boards. Thank you!

Question: Can I connect 2 resolvers to Gen 3 Prius Inverter

Hello everyone, I am doing a conversion with a Gen 3 Prius Inverter and gearbox, and will be using both MG1 and MG2. I have already welded the PSD, and have the dual motor (V1d) board from EVBMW. Looking at the pinout for the idc connector for the bord, I can only see connections for one resolver. M...

I have been using ST-Link since I was having trouble with the cube programmer earlier. It returned 0xff not 0xffff. For now I would like to try and make these chips work. Pretty much all of my soldering experience is installing the connectors on this board and some parts of the power stage that were...

Re: Need Help: STM32 Trouble Programming [SOLVED]

I was able to get that excess flux off of the board, and I renamed each ESP network so that they can be identified (I can now connect to either while both ESPs are installed). I just replaced the MAX735CSA+ on IC17, now I get a consistent -5V and it is not heating up a lot like the old one did. The ...

Sorry for the delay since last post.

When both are on the board, I still only recei...

It looks like I need to add power to the ESP modules from a capacitor, this may be why I am only getting one network. After this weekend I will be back home with a 12v supply again and will test both modules. Here are photos of MG2 chip, MG1 chip, and info from the ST link: IMG_5837.jpg IMG_5838.jpg...

Re: Prius Gen 3 Dual Motor Logic Board Support Thread

I saw the V1c B4 files Damien released, from which I can determine the L5, L7, and R65 (should be the same parts for my V1d right?) but the V1c BOM did not have the info for IC17, C93, C91, C92, or D9. Wondering if anyone can help with these.
Thanks!
