So I 've got most connections done , but I'm a bit stumped by JP3 main bd. uvlo pin . It's not connected on the adapter board , or is it ? If not , do I need to supply 3v3 to it , or is that already supplied from the mainboard? Same question re the desat pin, except that is connected on the adapter ...

Oh dear !
might I suggest some u channel steel

Well done , Johannes !
Just to be clear , do I swap PWM phases 1 and 3 , top and bottom , on the adapter board ?
Almost ready to try spinning the motor .

Thanks for all your advice, I know what to do now !
regards,

hello,
I have a leaf motor and 24KWh battery. Does anyone have any recommendations for the most
cost effective battery cable,and where to get it from ? i was thinking of 50sq.mm. Also ,does it have to be orange if it's in orange conduit?

Well done Johannes !
Can I just ask about your DC-DC converter - Is it a meanwell ac/dc psu ? I've been looking at the meanwell range
and their dc/dc converters are quite expensive .

Hi folks, Please excuse me butting in , I don't know much about motors or coding , but Paul Holmes runs a routine that establishes the motor parameters first, and after that it's good to go . I presume it's something along the lines of the leaf resolver code stamped on the motor ? Sorry to interrupt.

A bit late but here's mine ,gen2 ,

Quick update ! The firmware was being flashed to the 8266 all the time , but because I couldn't alter the ssid or create a password ,or load spiffs I didn't think the firmware had flashed properly - if that makes sense. Anyway ,loaded spiffs using curl - seems you have to use the full path to the fi...

Yes , I did. I have three 8266's now and I'm starting to think it must be the usb-serial cable . If I try putty to communicate with it I get no response from two of the 8266s . The 3rd responds with version no. etc. But I haven't tried to flash this one ,so I'm not sure .Maybe my attempts to flash t...

Chapter 3 ! After a lot of trial and error experiments with different versions of Arduino ide and esp8266 boards, I got to the point where I could compile FSbrowser.ino . So I exported the .bin file and tried to flash it to the esp8266 , using esptool . After that my pc still sees"esp_56520&quo...

The continuing saga ! Got to flash the FS Browser file ! My PC can see it and it says it's connected - but the ssid is eps_F52560 ? Also no password asked for . I followed Johnannes instructions to change the line beginning "WiFi begin " and put inverter as the ssid and a password, but the...

Thank you dima - I'm not going mad after all !
Will give it a try tommorrow.

Thanks Dima , but I get even more errors with this ! There are also other libraries required and Ive tried commenting them out but it gets too involved for me ! Would you or someone else try compiling Johannes code from FSBrowser.ino and see what you get ,please- cos this is driving me nuts - it sho...

That's exactly what I've done !
usb -serial cable is from Olimex,with their driver.
port is set to not use fifo buffer- not sure about that. Flow control set to none.
Oh - I've copied and pasted the code into the IDE , could that be a problem ?

Could be Brexit Gremlins - I voted remain!

Thanks Johannes, but I've run into problems on the first line !
I have the esp8266 libraries installed , but when I try to compile the FSBrowser.ino
there are some errors. I've tried this more than once including using the latest Arduino IDE and reloading the
libraries .

Right , I have just received a new 8266 ,and a usb-serial cable , but before I try again can someone confirm which file(s) is the firmware - it should be a .bin file -right? Can I use the Arduino ide for this or should I use the esptool ? Assuming I can flash the firmware ,do I then flash the spiffs...

Thanks , clearer now !

Thanks Dima .
Forgive me ,but just to clarify, can I use method 2 and do I then upload the stm32 loader .bin ?
Are any other files required - I need to understand what is stored in the 8266 as opposed to the stm 32.
Remember , you are talking to a dummy !

My pc does see the esp8266 , but it won't connect and ,apart from at switch on, there is no green light .
Same on stm 32. Is it terminal ,doctor?

Ok, I followed your instructions and yes it worked ! So I thought I'd be clever and update
the loader to avoid this happening again and Hey Presto ! - back to square one and
now I cant connect to the 8266 at all !

Thanks ! I'll try it tomorrow.

No , it doesn't . I'm guessing the failed update has mangled the firmware. Is there a way around this ?
I have checked the voltage at the reset button , that seems right, but on pressing the reset Iseem to remember the power led
would dip in brightness , but now it stays light constantly.

Hello, I'm not sure where the problem lies , but the esp8266 connects ok but drops out after a short time . power light on mainboard is always on , but no green led ? I have followed Johannes' instructions on installing easy php and I think thats ok . Before this started happening I tried to update ...

I'd like to second the request for a BMS section . I don't know if Johannes has plans for a bms build , but I have a Leaf pack and would love to use the bms in that as it is - maybe a micro controller which also looks after DC-DC and battery charger - if only I could code ! but old dogs , new tricks...
