    New "TSDZ2 Torque Sensor Central Motor"

    I don't know about the display, but I always get failed flash if the wall charger is connected to the battery. I am not sure why (maybe power supply noise,.. but I don't have no ground loops - laptop powered from battery). - One time my flash got corrupted badly and I needed to boot the...

    New "TSDZ2 Torque Sensor Central Motor"

    Yes. You can use stvp. You can open this stvp project configuration from TSDZ2-Smart-EBike-1/tools/ST_Vision_Programming.stp at master · emmebrusa/TSDZ2-Smart-EBike-1 or configure your CPU manually in the options menu. Then open the option byte hex file and then program th ecurrent tab...

    TSDZ2 Versions - ECU possibility

    Well, it might be beneficial in some scenarios to replace only white gear. One of the sources of torque delay is that we have to wait for the motor to accelerate to match pedals speed. By using white gear in old tsdz2, we would be initially accelerating the motor with our legs. This would also...

    TSDZ2 Versions - ECU possibility

    Is white gear interchangeable with blue gear then? It seems that the white gear doesn't have an integrated one-way clutch for the motor: So if you have TSDZ2B version of the main gear (with two one-way clutches) and blue gear which which also has a one-way clutch, then the blue gear one-way...

    TSDZ2 firmware flashing issues (and when to give up!)

    Another thing that works much more reliably (even over a bit longer cable lengths) is flashing using a slower stm8flash instead of STVP_CmdLine. (At least on Windows - see example). But last time it got so bad for me after failed flashing over a longer cable that I needed to use the 3.3V...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Ok, if that is the rationale then I can agree - connecting some external capacitive load to 5V line could potentially overload the voltage regulators, burn and short them out and so possibly the high voltage could end up on 5V line. Also maybe connecting programmer 3.3V line by mistake could...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    How would high voltage find its way to 5V line? If anything, someone could confuse 6V from headlights. So I don't understand reason for disconnecting the battery.

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    What has CANbus had to do with anti-tampering? If anything, at least the communication can be hackable. I can imagine with fast communication the high-level control portion would be offloaded to a more powerful display controller in which case people could intercept and command torque and...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Try my optimized build script branch. https://github.com/dzid26/TSDZ2-Smart-EBike/tree/building Use Java configurator normally, but you will actually see what is going on in the command window. Also, for walk mode you need to first enable 6km/h function in VLCD5...

    Hardware temperature control tsdz2

    Does anyone have motor case temperature, battery current, voltage and wheel speed and cadence dataset? I was thinking it of simple temperature estimation. The algorithm would estimate three states - winding temperature and motor temperature (where we measure) and case temperature. The...

    Hailong G56 Case / BMS fittment

    Very cool. It seems you used this kind of BMS: https://www.aliexpress.com/item/1005003740153567.html I wonder if 4 pins inside have serial connection... Anyway, here is the cell layout. https://e4bike.ru/page/battery-shape-configurator?c=71800501404160152457154504166550191510258177259130194 I...
