Dear sunny,

can you tell me which components you are using? Controller, Charger etc? And which brand they are from.

Did you get the display working?

Thans,

Juka

Hi
I removed everything electronic from the scooter, and only used the controller that I linked

Only cut the two bigger wires from the stock controller :
-The 9-pin juliet : 6 smaller ones are the hall sensor, 3 bigger one are the motor phase
-The power cable

To use the stock battery I tore it appart, and bypassed the BMS for discharge function, wired the positive directly on the cell #13
For charging it is still protected by the BMS

Oh and I also got two other scooters, and I'm currently developping a two-motors version :twisted:

Took a rear wheel, cut the front fork to get the motor inside
Already wired the two controllers on the same throttle

Just need to repaint it and put everything back together
I think that it will be nut :twisted: :twisted: :twisted:

Located down just aside the motor controller.

I felt forced to open up a new topic since nobody seems to read the original post of mine and still a lot Jerries try their luck with random UART codes to deal with the ES400 claiming they don't work while ignoring the content I gave them :cry:
I caught a living ES400 and did a record on its logic states, as far as I had my process DIO0 of my record (yellow line) seems to be CAN low @250khz, DIO2 seems t be some kind of CAN hight but due to the fact that I can just set the threshold for all channels in common on my logic analyzer it can't interpret the CAN high 1 and 0 levels correctly because CAN High has different levels and I was running out of time for a second run because someone else was already ringing for the scooter :roll:
I had to upload my records outside the forum because they got too big to be uploaded here due to the high sample rates of 5Msamples/s. So here's the link:

https://www.file-upload.net/download-13 ... h.rar.html

It is compressed with Winrar, no PW and also includes pictures from the process. To open the record files use Waveforms that can be downloaded from Digilents website, it will run in demo mode without a piece of Digilents hardware attached but all decoder functions are available on the green little plus button even when the program sometimes is a pain in the *ss to use by zooming in and scroll left/right. I you need measuring cursors take the buttons in the upper right corner of the logic window. Have much fun with decoding, I'll use my next few days to build a data logger that can be installed inside a living ES400 to sniff the signal they're using to unlock the battery compartment when changing the battery as soon as I found out what protocol the board in the lock mechanism speaks :) And now let the race for the first unlocks begin :mrgreen: If you got questions let me know.

Hello friends,
is anyone here still on the development?
I got a scooter and have disassembled and cleaned the controller. What a mess.
Is anyone able or can someone explain to me how to read the STM32 F103C8T6 if this is possible. Maybe the firmware can be changed so that the controller no longer needs to be activated via CAN?
I have a few more pictures for you.
