Re: Develop a QCA7000 board?
Another milestone reached today. I ordered 10 QCA7005 chips to JLCPCBs factory and can now select it for assembly :) This is fantastic news, and the price is perfectly reasonable considering the value of the finished board! Looking forward to seeing some "v1" boards. :idea: :idea: :idea:

Re: Rear SDU on foc?
Thx for the fast response and explanation. So a async motor we don't use the foc, only for permanent magnet motors? Correct. FOC is (probably) superior, but extremely difficult to implement on an async (induction) motors. Openinverter only supports FOC on permanent magnet motors. Don't worry though...

Re: Develop a QCA7000 board?
We've also got the chip serial which is unique This sounds good. If we append the STM32 serial number to the 02:: prefix, we should get a nice unique and consistent address. A) We decide we generate those for the users of focci. The easiest way (for now) is to use a local administered adress. I per...

Re: Develop a QCA7000 board?
Since we don't have a Vendor ID, the best way to generate a valid MAC address is to use a "locally administered" address. For this to be valid, bit 0 of the first byte should be zero, to indicate a unicast address, and but 1 of the first byte should be one, to indicate locally administered...

Re: Zombieverter and Tesla SDU Openinverter
How does Zombieverter, in combination with SDU (or LDU), handle the overcurrent event when it is not aware of the tripmode (=1) setting of the OI board in the DU? Zombie would not be aware of the error. It will simply leave the contactors closed until you turn the ignition key off. This is the beha...

Re: Investigating using sine f/w
Usually a hardware failure would cause an immediate trip, excessive load under current seems like a configuration issue.
What hardware are you using, and what parameters?

Re: Develop a QCA7000 board?
Where do you guys source the QCA7005 chips? Pretty sure the answer is Aliexpress. There are several sellers there offering them. However perhaps Uhi can point to a specific seller as I imagine it's a bit of a gamble what you'll actually get. Maybe one day we get to the stage where it'll be worth sh...

Re: About to spin for the 1st time, but how to properly turn OFF the system [SOLVED]
As long as the motor is not spinning, and no throttle is applied (ideally in neutral) then it's safe to disconnect the HV.
You can turn off the HV first, or the HV and LV simultaneously.

Re: Wanted: Arduino programmed in North America
If I'm understanding correctly, the program already exists.
I know you said you don't have much time, but I'd say loading an existing program onto an Arduino is extremely easy. I would strongly suggest that you at least try. The page you linked provides a program that will do this.

Please could we create some tags to properly label "feature requests" and "bugs"?

Re: Accelerator pedal dead zone
One nice thing about making regen proportional to speed is that as well as eliminating the deadzone, it also replaces brkrampstr.

Please post your configuration and wait until someone looks over it to make sure you don't break anything. It sounds like you haven't calibrated your throttle input, which is definitely necessary

Re: SDU: No udc voltage
If you're definitely seeing 186V going into the inverter and at the same time, udc is showing near zero then one of two things must be wrong:
1) The udc measurement circuit is broken.
2) The udcgain parameter is wrong
I'm not sure if this helps you, but I can't think what else could be wrong here.

I've just had a look at the FOCCCI board (actually mostly just the buck regulator), and I would strongly recommend making some layout improvements here for the next revision of the board. In particular, the current paths for the input and output capacitors are much too long. 1) The input capacitor (...
