yes

Ok, but do you use this circuit to also signal to the charger to start or is it just for auxilliaries? Asking because i plan on using PP signal to start aux stuff in my pug and i want to know if i need anything more... Yes the circuit also powers the charger itself. I guess it would work likewise w...

Alright yes, basically the Tesla charger board pulls down CP and the circuit I added tries to not alter the CP signal at all but just "reads" it

See here:

Basically this is a similar approach with 4 channels viewtopic.php?t=60

Even then good resolution around 1mV is hard to obtain

Missed this. Software arbitrarily limits to 1000 Hz

Nice, now besides EV grin you also have solar grin. Will you also do some sort of energy storage?
Brave to do it all by yourself

I think I found a bug in the later firmware versions. As soon as you save the parameters to flash it seems the CAN map is lost on the next reboot. Will investigate this. If in doubt, type can print into the custom command field and send it. This should yield a long output above the parameter table. ...

I have integrated above circuit into a Gen2 Tesla charger. So now permanent 12V can be fed in via Pin B12 which is otherwise unused. Its traces are beefy enough to carry the current. CP and GND are stolen from the control board as well. Switched 12V is then send back to what is usually the 12V suppl...

Early forum release (German, with subtitles)

We talked to the dealer last week and supposedly they will receive the source codes and employ a software developer to fix these problems. So they will probably receive some documentation, too. Maybe they will give it to me. BTW we tested a bit more on that Veefil station and I looked up the error c...

Wow, that is truly exciting! We really need a full open source implementation of CCS that lets everyone play with it until it works with all chargers. Had some bad experience with a Chinese car (video coming) that only worked on every other charger and would have loved to break out my laptop and fix...

It seems like you've hit the point where you'd need someone stand next to you with a scope in their hand and checking exactly what's going on. With this short feedback loop it'd probably take 10 minutes to get it running or at least diagnose why it isn't. I am out of ideas but like yourself I think ...

Very cool!

If you feel like printing the logo anywhere I attached a vector graphic of it

Just put some on order. I've added an extra serial daisy chain for enabling mux control or ADC control on a respective board. Mux, ADC and the 4-channel port extender all run via I2C and I have made the SDA signal differential with a CAN transceiver. The board contains no microcontroller just all 74...

Yes indeed the CAN messages are sent unconditionally. Is there any input to the CAN transceiver on pin 1? And, silly question, did you perhaps flash some firmware that doesn't belong there? Nothing stops you from flashing stm32_sine to the charger. I think it might even blink the led

I would think that is what happens when you have no load on the motor. Try decreasing throtcur maybe even below 1A to verify this. Also try using idlemode=always and idlespeed=100 to see if you have speed control

Because if there are mutual IDs you need to also distinguish which interface it is coming from

So in manual mode it is smooth, in run mode it is not?

Is it so that one cannot have messages with the same id on both the powertrain- and vehicle CAN? Good point. I guess this should be different callback functions. Since powertrain and vehicle CAN may be configured a common handler should be called with the interface number. void CommonHandler(int in...

Check again, on this forum you have limited rights until your first post is approved. That has proven to be a good armor against spammers

It's the same function because in main():

Circuit diagram is pretty much standard openinverter and there is no known problem like that. Could it just be an issue with encoder or gate driver connection?

Yes, in boost mode the current sensor measures input current

I noticed numimp=39 but should be 36. Not sure if that should lead to immediate overcurrent though but should certainly be corrected
