Good job
One things I noticed, the vacuum pump comes on often and could use some turn-off hysteresis. How is it controlled?

Re: ID.3 and other MEB battery packs in conversions
Yes, its a remix of Toms code and tailored for 8 modules:

Re: Driving mechanical speedo from CAN
Welcome
An arduino can hack it. You'd not use 0-5V but rather PWM as that is more common.
When creating new threads use a descriptive title. I've changed it for you

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU
You could move the "negative" contactor between 48 and 49 and move positive and precharge to the end of the pack. Don't break between 41 and 42, by Murphys law this can and will go wrong

Collection of Part Numbers
Following up on a kind nudge by no one else but The Greg I created a wiki page where we can collect various part numbers for connectors, even if this creates redundancies to the existing detailed board pages.

Please extend like there's no tomorrow

Re: Volt Contactor Amp Draw
I have clarified this sentence in the wiki. Putting two contactors in series doesn't double their current capability and I'm sure it's not what arber meant to say. They need to be paralleled for double current capability

Re: Am I to dumb for Open Inverter
Leave out all the contactor stuff for now and connect the battery directly to have less room for errors.
FOC itself doesn't care about the voltage but udcsw and udcmin should be set to 0 for the first tests

Yes, that would require much more RAM text data bss dec hex filename 683952 2112 154504 840568 cd378 stm32_ccs Solution would be either try to butcher some redundant stuff or bigger MCU like https://www.digikey.de/de/products/detail/stmicroelectronics/STM32U575RIT6Q/18085716 or https://jlcpcb.com/pa...

Re: Big-Endian CAN mapping
Hmm, the bit order shouldn't be changed at all, just the byte order: word = (bptr[0] << 24) | (bptr[1] << 16) | (bptr[2] << 8) | bptr[3]; I think it should be consistent with SavvyCAN that the position now specifies the "end" of the data item. So little endian bit 0, length 16 becomes big ...

Forgot the obvious: when the inverter is in Run mode it won't save (because it interrupts the control loop). It must be in stop mode. The CAN Ui doesn't report this yet...

Hmm, not sure. It's the Nissan cable 296B1-3NF1A
I assume 35mm² or 50mm². I can only measure cable diameter. Used to charge at 180A on Aral Pulse

The latest web ui hides SWD update as it only works with additional connections. And even then it never really worked for me

Re: First-Time Config of FOCCI And CCS1 vehicle charging
I think the 5% PWM should start as soon as the charger is powered and you have 2k7 pull-down to PE (not PP). When you say "PP" do you mean "PE" i.e. Earth? Doesn't really make much sense to measure between CP and PP
