Sound like a cause for failure? No, 5V pins are on many other connectors. Can you please attach pictures directly to your post (attachment in Full Editor). When I click these imgur ones I only see a blank page plus they tend to vanish. This explosion looks a bit like you fed 12V into one of the ULN...

Great! Let us know how it went

Gain=0 and x*0 is 0 Make Gain=1 and you'll get your data

In the diagram it looks like you're feeding 5V to Foccci? This is not necessary
The CCR might be redundant as the driver chips are quite strong, lets say 5A total contactor current (limited by reverse protection diode)

How would that be possible? On your photo it looks correct plus I doubt you can mangle a 16-pin header into 14 holes

You're indexes are off by one and you're decoding big endian. Try this

sounds correct to me

Well if the Wifi adapter has a CAN connection to Foccci but Orion does not then check the CAN Link between the two and connect your CAN dongle to various junctions to see where data is lost. I'm assuming the CAN link must work though if the ESP32 board communicates? Exactly, I think a new board is u...

Yes, amp hours in fact. But then you need to know what the actual capacity is plus you drift away over time because of measurement tolerance

The OI 16-channel BMS is supposed the be accurate enough to estimate LFP SoC. But it needs a 2 hour resting period because the dielectric effects take super long to taper off.
As always hacking the OEM BMS would be the premier approach

It's got this now, but of course that requires flashing the latest Web UI. That will take a while to trickle through

If the QCA reports "Bootloader" as software version, it was not able to load its firmware from the SPI flash Coincidentally I just had that exact symptom. Turns out the QCA had some bad solder joints. Quite intuitively on the side pointing towards the flash. Also the SPI flash itself had ...

Oh!

Yes, leave a note and I'll flash the Leaf params on it

Just to confirm: you flashed stm32_loader.hex and stm32_sine.hex (or foc) and you get a 5 Hz blinky LED (provided the through hole board has got one?)

Hmm it's reverse polarity protected. What do you think melted?

Do I have to activate can on the brainboard or something like that? You need firmware at least 5.27.R and canspeed 500 . All else doesn't matter. You should also update the ESP32 firmware itself, it has some reliability improvements https://github.com/jsphuebner/esp32-web-interface/tree/can-backend...

Mine turns off at 400V and turns back on at 393V. So short acceleration bursts are sufficient to start it back up but likely short regen bursts turn it off again.

Documentation is still growing Where it says "Node ID" in the left navigation bar you need to enter "22". then wait a few seconds and turn on refresh. It was discussed before but even I can't find it right now

EDIT: touching it here: https://openinverter.org/wiki/CCS32Clara

argh, the picture is wrong. The relay is connected before the reverse polarity diode.
I saw it on the scope that while the relay was on supply voltage (behind the diode) had risen from 12 to 20V!

Overlooked that. But it wouldn't actively suppress reception (and display)?

looks correctly mapped. Are you seeing Clara messages in your CAN logger also (0x108 and 0x109)? Suspecting a physical issue

Is focci able to detect the duty of CP and if it's over 5% switch over the CP to the OBC for AC charging? Like Tom says, it's not really intended. What I do see is removing the 2k7 from foccci and just paralleling OBC and Foccci. Then the 2k7 inside the charger is used to enter state B. So when DC ...

Any power source that can't absorb energy is risky, in case you accidentally brake (regen) the motor the energy has nowhere to go. You can turn off regen e.g. with throtmin=0 but it can still happen e.g. when playing with manualiq So agree with Matt, a battery with fuse and cooker element in paralle...

Ok, good to know. I also run throtcur=5.5, are you running in fact double that because you only measure on one power stage?

In that case your tremor would just be an amplified version of mine. If I fix the subtle one it would fix the the strong one as well

Can you try going back to zero-ish and instead activate resolver pinswap? Not sure if it makes a difference mathematically, just to test

Only thing that surprises me is syncofs. It is usually around 0 for EM57. How did you arrive at this?
