Re: The motor turns in the opposite direction

Do not alter syncofs.

Just reverse your gear selection either per dirmode parameter or physically and be happy. Reverse=Forward

Also upgrade to the latest firmware for safe operation: https://github.com/jsphuebner/stm32-sine/releases (stm32_foc.bin)

Bargain Bin

For years I have had boards blocking my storage space that I don't have the time or ability to really sell as a product. Mostly looking to get rid of them and maybe recoup some material cost. These are now available in the "meta product" on the shop: https://openinverter.org/shop/index.php...

Re: Zombieverter Activity Lights only with Wifi Module

Dodgy connection or bad 5V reg? Thou shall measure voltages. do 12V arrive at the regulator and do 5V come out? Do 3v3 come from the 1117 3v3 reg?

Re: [WIP] 1971 Beetle - Tesla SDU and CATL cells

Hopefully someone out there can help me out with details on how to use these BMS? I'm not sure whether these have been reverse engineered. I'm assuming they are "dumb" modules that report to some main module and executes its balancing commands. You can find code for calculating various hi...

Re: Develop a QCA7000 board?

Finally got around to re-assigning the connector pins and made the flash SPI easier to access. Moved some components around to reflect the new placement also. I'm calling it 4.5b as it is electrically identical to 4.5. Didn't want to burn up another version resistor. Does that make sense? grafik.png...

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.

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
