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

I have just flashed 850C_v0.4.2-bootloader.bin with home made bootloader box successfully and display turns on however the vertical screen flip is still present. Also seems that I cannot flash it anymore as the display is not reacting to flashing signals from USBUART module as before. Is there a ch...

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

Help needed: I have installed the OpenSource firmware without problems on my TSDZ2 (0.19.0). But I didn‘t succeed to install the firmware on the 850C using the USB to UART cable method (anybody successful yet?) so I bought the bootloader from Eco Cycles. Arrived today and it worked perfectly well. ...

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

Beta1 I found backward resistance that kicks in when moving bike faster backwards. At low speed there is no any resistance. Also had feeling that motor stops much quicker than on alfa UPDATE: today did another ride without any backward resistance.. this could be very uniq case or upcoming HW issue..?

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

I bet you didn't buy the 850C from the links refered on the wiki. We should have a stable release to solve your issue very soon. The developers already found a solution, they are just finishing the thing. Maybe in 1 or 2 days there will the the new firmware release. I would be happy if this was the...

Alfa10
The MAX speed (submenu 7.2) not showing correct values. When riding 30km/h the values bounce from 3 to 14km/h

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

Note that converter must be 3.3V. With bootloader box the 3.3V pin is not used. The UART chip is powered via the main source of power 27V or more. In the case of flashing firmware on the TSDZ2, users report errors and the solution is to use very short cables... Maybe you can try another converter. ...

Has anyone tried with success to flash 850C display with home made boot-loader (USBtoUART) ? In my case flashing starts fine data is transmitted but it gets interrupted and I could not get beyond 40%. Really strange that each time it fails with different percentage. I was trying different power sour...

Call me impatient but what is the ETA for the official 0.20 Beta ?
Correct me if I am wrong but this is important milestone for Qmarco to start working on his implementation for original displays and as well for Casainho to start with 850C/SW102 firmware versions for 0.20..

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

Do you mean that it should use the assist level just before eMTB? That could be possible to fix but I am afraid that some users have really high values and could get surprised if accidentally on eMTB and enabling Walk Assist. I understand the inconvenience you are trying to solve though! EDIT: Have...

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

Clarification: If anyone likes how the eMTB mode works it is very similar to Torque Assist so give Torque Assist a try! If we had a sensitivity of zero on eMTB it would be just like Torque Assist and just a linear function. So if Torque Assist is setup properly the transition to eMTB will be comple...

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

48V high cadence mode - (menu 0:3: value 2 ) is not working for me, the engine stops above 500 ERPS as it would do with normal 48V mode. I did memory cleanup by writing zeros (even it is not needed in alfa2 where the EPROM issues is already solved) so that should not be the case. Sad to hear that! ...

But I think that you would rather I remove the entire "Cadence Double Resolution" and save that particular thing for the future. Let's see first how all of this works. If we are talking about shutoff, why not start using different cadence values, one for startup and other for shutoff? In my humble ...
