    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    I've tried it with this method and I've got very different value from the default. On one bike I've gotten the result of 48,5 and 43,4 (measured twice, since 1st time was unreliable). On the other bike I got 44,4 (only measured once correctly). Seems like this calibration method (in conjuction...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Yeah that's what I did: 1.) restored original optionbyte and programmemory in STVP 2.) closed STVP and flashed with Java configurator 3.) closed Java configurator, opened STVP to check and flash original optionbyte again (because it was different again). Hasn't happened again after that fist...

    I've measured and calibrated the Torque ADC values - min:130 max:255. Can't measure the ADC conversion factor tho, since I don't have a 20kg weight. What I noticed is that I'm having trouble flashing the motor, I have to flash the original OptionByte and DataMemory for it to work (even than...

    I haven't measured the ADC values yet. But it doesn't sound like its that's the same problem. Regardless of the sensitivity of the sensor, the motor should not be running if power assist level is at Off. This post (point 1) describes a similar problem. When it happened to me i was also using...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    There is a bug in this firmware where the motor keeps working even without pedaling or even when the power assist level is at 0 (off) - sort of like if the thumb throttle was stuck (but it is not). The restart of the controller (vlcd5) fixes it. I'm not sure of the exact situation leading to the...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Thanks for this info, I had the same problem just now, when I could read the data from the motor (in ST Visual Programmer) but couldn't program the Program Memory (Error : Problem while trying to Reset swim and device. Apply a Power On Reset). Restoring Data Memory and Option Byte from original...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Oh i see, thank you for the information TimV :thumb: Edit: I've successfully flashed the firmware and already the motor assist is a lot smoother than the default levels. Just need to tweak the settings a bit and it'll be perfect. (It did take me quite a while to decode the instructions from...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    I've got an 8-pin version of the motor (VLCD5 with throttle) and I've been trying to figure out how to connect the STLinkV2 but I can't find any diagrams for the 8-pin version (all guides show only the 6-pin version). Does anyone have the information about flashing the 8-pin motor?
