Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

For me 18 beta cruise was working flawlessly, I never did the speed preset though. Didn't use too much because it was too cold to go without pedalling :) And the implementation of walk assist is really good as well, I am just thinking of putting parallel switch to down button to enable holding and w...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I managed to install 18 beta as well. For me the headache was is not clearing rom with option byte (had a strange issue when numbers in lower lcd3 row did not appear and when button is pressed the main kmh just blinked), other than that everything works as expected. Tomorrow will do a field test of ...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

As for walk assist or any other function that rotates the wheel without having to hold a button or pedal I would strongly caution against that. The obvious is an accident with the rider not able to switch the motor off, but these bikes also go into crowded public spaces including trains where it is...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I agree that both cruise and walk assist like that would be perfect implementation. I think then the firmware would have everything I want :) :thumb: Thanks for the development and let us know when we can test the firmwares :)

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

There are no issues using 48v battery using both firmwares, original or opensource. For original you'll have to change some bits using st-link, for opensource you can just choose tha correct voltage on the display. I am using 12S, however I think it should be fine with 13S as well. My 36v battery is...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I have LCD3 but I was reffering not to the current consumption/pedalling power in watts, but watt hours of your pedalling - e.g. If I pedalled 2h with an average of 200w it woudl show 400wh, plus motor was contributing 250 w these 2h, so the battery consumption would be 500wh. Totall energy for the ...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

One crazy idea came in my mind :) , would it be hard to implement human wh on the screen? I would find it really super interesting to see how much power in wh were used from battery and compare it to pedalling, particularly for longer trips :) p.s. Still on 14.3 but looking forward to test 16 in a f...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Hey, first thanks for the great work on the project :bigthumb: Already drove quite a bit on my bike with the TSDZ2 and OpenSource firmware. With my 140kg and 1kwh battery (96 cells 2x 6s in series) can do ~ 70km which is very fine for me. On a lazy mode consuming ~500w when going on flat at ~30km/h ...
