    Lishui "Open Source Firmware" project / KingMeter 5S

    2 hours of random numbers, found that P doesnt matter if 5 or 600... the I is the key. got best results when set at 7. thank you. any idea about the display speed getting stuck? i found that it always shows 2km-h once you touch throttle after startup, then goes to zero after first speed sensor...

    @stancecoke hello, Im trying on a gear hub motor now, made a tiny little modification to this file, to try again if flashing fails, because im having problems with my st link. check if you like it. now on the hub im getting osciclation from 18 to 26kmh. no load rpm is 36kmh.. I tried speedshift...

    @stancecoke Just so you know, I briefly tested the firmware on a mulitprotocol display, the push assist works on everything, on kunteng protocol it tries to run the motor with like one amp, on bafang I had to set 10 times the real gear ratio. light switch works on all protocols. the display...

    One more thing I noticed. Low voltage cutoff at full throttle is kind of pulsing the power about 4 times a secound, instead of cutting it completely or maintaining the set minimum voltage. Have not tried high voltage limit because regen doesn't work, but I expect it to be there same. Maybe you...

    @stancecoke just now tested with PLL disabled, much better, full throttle from standstill or even moving slightly backwards works great, but when it's moving just a bit forward when applying throttle it kicks for some reason and at no load there's some pulses, not noticeable while riding, just...

    Are Cell Spacers Necessary?

    Simply said, heating is not an issue. If you don't plan to have a fan pushing air through, just glue them on top of each other as you want.. let me know what capacity you got in 😉

    What kind of safety measures do you take when building battery at home?

    Fully charged 21s hurts just a little, not enough to get scared and throw the battery 🤣

    Sabvoton 72200 e brake throttle wires

    I had this problem too, sold the controller for profit and got one with regen lever input 😉 best solution in my opinion, I doubt you will be able to get another firmware to let you change in the app, but if you do, send it to me and I'll tell you where to connect the signal wire for brake lever...

    Change in the code worked ( brake lever cuts the throttle) but it looks like the regen is not working with wheel in air.. will test tomorrow on road. Speed PLL helped maybe.. now with a little load I don't even notice the switch, but no load maybe it vibrates a bit more. Still better than that...

    @stancecoke can you please point me where to change linear brake min and max voltage? im now testing on a scooter which needs regen and i have 0.9v on the brake not pressed and 3.4 when pressed all the way, so its still braking. and theres a little problem at low speed it has low power and then...

    Lishui controller short circuit

    I just got third controller with the same problem, so definitely common.

    Lishui controller short circuit

    So the one I have spare is F103 C8T6 so it probably won't work.. if you wonder how I can change it, I have EBICS firmware flashed, from stancecoke, so that would probably work on a fresh processor too..

    Lishui controller short circuit

    Hello, thank you for your opinion, only the procesor is heating when 5v applied. When it's turned on on 36v battery, the lm317 and the big resistor is heating. When it's not connected to battery, just 12v on the output of lm317, then the 5v regulator is heating, and when I connect 5v on the...

    I started a thread about my problem with 2 same lishui controllers, not related to this at all, but I will put link here if anyone has any idea what's wrong. I'm just curious to find out because it looks like a common problem with this model number...

    Lishui controller short circuit

    I have 2 controllers with the same problem, overheating and turning off even with light load they are the same model number: LSW772-159F they have STM32FEB KC6T6 procesor, I narrowed the problem down to 5v line, after connecting limited current the processor boots and starts heating, interesting...

    Success! I found controller with brake wire, soldered throttle to SP and the detection started, also it's pretty fast. (I thought the detection will start itself when I set detection in Java tool, but it doesn't) Brake icon shows on kunteng display, power, throttle, but battery doesn't show...

    Maybe easier to push brake and full throttle so the identification starts? But the controller I'm testing doesn't have BK pin. Just EBS, will it work? Also just hall sensor connector on TA pin, but throttle will work on that right? Or TB? When I set auto identify debug in Java tool I still...

    I don't know if you understood, I flashed successfuly but it's not working. Red led Is flashing faster than normal as some fault and it's not doing anything, I set auto identify debug option and the motor doesn't start. Is the bootloader needed for it to run? Can you give a little hint how to...

    So I was able to flash by stlink after a lot of struggle. I can write a more detailed "how to" for non-programers if you want. But now the controller red led is flashing fast. Do you have implemented any fault codes on display? If you help me get it running I can send you a free controller...

    I found another controller and it has those programming pins. I will try on that :roll:
