    New "TSDZ2 Torque Sensor Central Motor"

    from my rc times i remember running a brushless motor with a less agressive timing keeps the motor cooler. maybe thats also possible with the tsdz2?

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Hi would need that function too, since my bike lags from time to time and i want to find out if its the torque sensor or the pas sensor.... maybe try setting ui16_oem_wheel_speed to eg 50... before if(ui16_vlcd6_wheel_speed == 0) or try uint16_t ui16_temp; ui16_temp = (uint16_t)...

    Hi guys, Since my KT LCD3 died, is it possible to enable the TSDZ2 by simply connecting "green|P+|battery voltage" to "white|Vin|ground when LCD disabled and P+ (battery voltage) when LCD is enabled"? https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/Wire-KT-LCD3-to-TSDZ2 cheers...

    hi casainho, i would suggest to use the wheelspeed as a factor for the ramp up. since when on speed faster ramp up is no such a problem for gears compared when wheelspeed is low. so not use a constant but a var multiplied with wheelspeed should give a quick response when its mostly needed, when...

    I am running my 36V motor on 12S Lipos for about 1500km now without a problem. So 13S will no problem either.

    sounds good. might also smooth out the startup sequence from standing still since at the moment sometimes it fells like the gears have a hard time ;) so many good news today!

    i think the problems lies here: // disable boost if if ((ui8_torque_sensor == 0) || (ui8_startup_boost_timer == 0)) { and // disable fade if if ((ui8_torque_sensor_raw == 0) || (ui8_pas_cadence_rpm == 0) ||...

    Boost is a very nice feature for me. For instance when you ride around a corner its nice to have some extra boost to get to speed again. Or when i have to climb a short slope, i stop pedaling for a short amount and then use boost to do the climb without loosing speed. Its not that hard to...

    look at the video again. it did many attempts very similar, pedal, stop pedal, pedal again, similar pressure and cadence. you see the powerlevel (Configuration 9/6) on my display. first tries after starting pedaling again the motor immediately kicks in but look at the video at 0:23 the motor...

    cool feature! will be interesting to see how that feels. i did some research today on the lag issue. firmware version 14.3 lag definitely only occurs when boost enabled. https://drive.google.com/file/d/1C9-BkfBqgeXD1OBJrcdKneBWStuNWU90/view here in this video i reproduced the lag bug. it...

    maybe it would make sense to have up to 9 walk speeds. using up/down buttons when in walk mode sets the walkspeed. 0-9.

    no brake sensors here. will try to disable boost and see if lags are gone.

    unfortunately lag is still present in 14.3... i hard to analyse since its so random... most of the time it reacts fast, sometimes i needs 2 seconds before motor kicks in again.

    tried 14.3 "experimental high cadence mode" but its not working for me. motor is less efficient when around 90rpm cadence. (20-40 watt more power needed) less torque too. 36V motor with 12 cell lipo here.

    You get a used mobile phone with touch and everything for the price of a bafang 850c... You have GPS, Accelerometer, Bluetooth oboard ... Screen ontime should be about 5 hours for a charge. We just need to do an Android app thats all. Thats not hard to do. I can help here.

    Maybe we should just write an email to bafang, if we are lucky we get some info about the used display/driver.

    maybe we should add a eeprom config version number to the builds.check on boot if eeprom version in build not the same as eeprom version saved in eeprom. clear eeprom and set defaults from build. if no changes in eeprom layout no reset to default needed eg minor fixes in code

    like i proposed with my code changes. wouldn't it make sense to include the whole safety logic in one function at the end before powering the motor? so in the other parts of the code no safety checks have and shall be made? so similar to this code below but with added logic? maybe adding codes...
