Everything was fine until I changed slaveop to FWUpgrade and now it's on WaitAddr again. Leds on first board are solid as long as it's connected to master unit.

Thanks. That did the trick. The last email I got from you instructed me to move R12 to R5 instead of R6 ;) I have swapped all diodes and also added standard JST connectors on all boards. Have you prepared the first board? It needs to R6 to be moved over to R5 (pull-down instead of pull-up) Have you ...

So, I hooked up some cells for testing. Firmware 0.22B, slaveboard led:s are looping, opmode WaitAddr and that's about it. No voltages shows up. I have a strong feeling I forgot something. Is there supposed to be a jumper on the first slave? Edit: R12 moved to R5 on the first board and connected to ...

What is the default password for inverter6? I know that piece of paper is stored somewhere safe, but I can't remember where

For a guy like me who knows little of a lot of things, I've come to a point where I need a tap on the shoulder or a punch in the face to take the next step in my project. So I am restoring and converting a 1964 VW Beetle, and for this I will be using, Leaf gen 2 motor and inverter with V3 mainboard ...

I just got it all working, default motor settings were WAY off. I thought the Leaf board came with nissan motor settings pre-flashed. Assumption is the mother of all fuck-ups. Changed to Leaf settings from wiki and its revs silky smooth without errors Thanks for the heads up, will install update! I...

I need to get my hands on a scope to check if my resolver is bad. Motor is spinning and shaking Watched your movie, mine is currently on the bench too and when I finally got all the connections right and followed the instructions and hints, I was able to spin it up. Started slow but then it rocked ...

I need to get my hands on a scope to check if my resolver is bad.
Motor is spinning and shaking almost like a original VW air-cooled engine that runs on 2-3 cylinders. Maybe I should be happy with it as the way it is and call it "vintage feeling"

Voltage between R1 or GND and S4S1, S2, S4 is 1.5V

No feedback from resolver :( I've checked wiring again and it's all good. I also checked resistance from resolver to main connector and everything was in range according to a document I got from Langoo. Any suggestions what to check next? RES_R1 - GND = 13 ohm RES_S2 - RES_S4S1 = 29 ohm RES_S4S1 - R...

Thanks Damian. Fresh parameters and software now loaded but unfortunately error still remains.
When engaging the throttle motor makes sounds and tries to spin, but it's like it doesn't know which direction to spin at. I've tried both fwd and rev.

Resistor is replaced but I still get loresamp. But now at least the motor is trying to spin.
Seems I can't upload leaf parameters to 4.76 FOC firmware for some reason.

I checked again to be sure and the R44 is 1k2. Do I need to replace this then? Now I'm running latest software (FOC) and parameters but as soon as I start the inverter I get the WARN - LORESAMP error. If I start without connecting the resolver there's no errors and of course nothing happens when I e...

R40 = 4k7
R41 = 4k7
R42 = 3k3
R43 = 10k
R44 = 1k2

Well 1 out of 5 is correct

Hi, I'm trying to get my gen 2 motor to show a sign of life with no luck. The only error I get now is the loresamp. Wiring seems to be ok but I need some guidance to continue troubleshooting. I need to know which pins and what to measure and also if there is some parameters to check. 4.65.R-sine Rev...

What is the status for the first batch? Like I mentioned before, I'm interested in 24 slave modules and 2 isolator modules to use with SimpBMS at 500 kbps baud rate to match my DC/DC converter and charger.

I made the same mistake. Seems like Pin 26 isn't connected to anything?
If I'd like to get 5V to pin 26, can I just use whatever pin that has 5V output and solder a wire between them?

"Just a friendly reminder.."

Sign me up for 24 4-cell boards and two CAN isolator boards. If there are any left that is

I could try to figure out the wiring.

There are ten CMU's and one management unit inside the pack. I will do my best to find a car and get some canbus data out of it. Thanks for now. Here is some photos of the hardware.

Hi
How about Hyundai/Kia? I have a battery pack from Ioniq that I intend to use in my conversion of a 64 VW Beetle. It would be nice if I could use the OEM slaves.
