    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    No, haven't got into that part yet, I was so tired last night after getting it to work in the first place :) I'm gonna study the features a bit more now and see how the code works. Hoping to be of some help for this project somehow. I could immediately see few spots for code optimization at...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I bought a KT36SVPR controller after all and after investigating it for a while and finding out the read out protection was enabled, decided to go for it and flashed it with this firmware and presumably a safe configuration to begin with and then: Boom! Nothing happens... Well, I was kinda...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Did you ever solve the hall sensor auto learn stuff and purpose for other code for that matter? Not that I would need it for anything, but just like in TSDZ2 firmware there are a lot of references for the auto learn mode in KZQW22A code, but it's seems to be deliberately ignored. I was also...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I have a hunch this one cannot be altered much by changing the EEPROM values, the built-in programming connector tells me that this has some custom firmware tailored for the customer. My second clue was that the serial package from the led panel to the controller is only 5 bytes long and starts...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    Can't see much yet, I'm half way through freeing the board from the dessert. Fortunately in this case the programming connector was already there. The connections and layout are pretty generic, but like I said the brake signal goes to PB3. There's a wire to change throttle speed between 6 and...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    Yes, I'm aware of the other project as well, but like I said before the PAS sensor code doesn't match as this controller has only one PAS input. On the other hand that shouldn't require many changes to the TSDZ2 code and the rest of the code looks just too similar. My first guess is that there's...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    Sigh, back to the drawing board regarding my previous post. The controllers this firmware is intended for have STM8S105C6 with 32kB flash whereas my controller has STM8S105S4 with 16kB of flash :| So that answers my very first question, nobody has tried this firmware on KZQW22A.

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    Anyone tried this firmware with a Tongsheng KZQW22A controller? The controller's ok, but I would prefer more options, starting with changing the ludicrously inconvenient assist level presets and making the controller protocol compatible with... well anything else but the unknown control panel it...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hello! Long time lurker, first time poster. I have a bike(one of those mass produced Chinese 20" fat bikes) with KZQW22A controller, which seems to be heavily customized for the purpose. Otherwise the controller looks like a regular stock model, but this one has an input to switch between...
