Re: Tool to manage openinverter via CAN

It has a fixed node id, I think 2. Check main where the CanSdo object is created.
It also needs to run the latest libopeninv

https://github.com/damienmaguire/Stm32- ... .cpp#L1049

Node id is 3 and it is tied to CAN1

Re: [DRIVING] 1940 Chevrolet with Tesla Motor

I'm reading a lot about coolant delete. Does it mean rotor cooling was over engineering practise in the first place?

Re: 2008 Nissan Quest Van with Tesla SDU. [FINISHED]

In the best case it's just an air pocket. In the worst case some inverter damage. Have you made sure coolant circulates bubble free?

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

It runs on an STM32 but the code should be more or less hardware independent.
I didn't figure out the BMS that was Tomdb https://github.com/Tom-evnut/VW-bms/tree/master/VWBMSV2 and I shamelessly stole from him ;)

Not sure where this post fits best as it is kind of a road trip, EV improvement and CCS mix. So, I went to Hamburg to meet Mathieu who has done various conversions like the Mustang and Toyota Land Cruiser. Plan was to get CCS up to speed on the latter and fix a few things on Touran.

Re: The motor turns in the opposite direction

The behaviour is expected, both motor and resolver have 4 polepairs so one physical turn is 4 electrical turns. I'm also puzzled that pinswap=6 stops the motor because the pins are swapped on the mini mainboard (https://openinverter.org/forum/viewtopic.php?t=2760) Can you post the output of http://1...

Sounds much like it. Maybe air or flow rate too low?

Re: The motor turns in the opposite direction

Like said, don't mess with any parameters, just accept that the label reverse means forward and vice versa.

It runs fine apart from spinning in the opposite direction, right?

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)

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...

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...

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.
