Re: New "TSDZ2 Torque Sensor Central Motor"

Hi, After about 50km with the original firmware, I got a package from Singapore yesterday, with the things needed for the Open Source f/w upgrade, Reprogramming the display was trivial, but the motor caused be issues with constant read errors and programming failures, and after an hour of shortenin...

If there is a way forward that allows any generic SW102 to be flashed with open source firmware then we are 100% in favor of that. So, this means that you as a seller, if an user render useless the SW102 because by mistake or on purpose did flash a no working bootloader version and ask a replace us...

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

The problem we have is that they require an NDA to gain access to their boot loader and technical documents. As...

One of that sellers is already selling online TSDZ2 and KT-LCD3 flashed with our firmware. Why not trust them? Trust aside, this seller charge for flashing and don't ship outside of north America. For a non north-american wanting to save $35 (+ expensive shipping if they were to ship anyway), that ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have a 2015 Krampus I would like to try with a TSDZ2 as well. My biggest concern is the diameter of the reduction gear housing and if it might clear the forged chainstay yoke used on the Krampus. I have been unable to find this dimension on any drawing online. Like you, I am trying to avoid the e...

So, there is cadence and torque sensor signal. Please try startup start without pedaling. Please tell if PWM duty-cycle value do increases when you pedal with torque... It should increase!! Are you sure brake signal is not active?? Ok, tested again after much rain. PWM is 0 pedaling with torque. Th...

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

I tested v19 beta 3 on a coaster brake motor. There is no backward resistance but I also have no power. I did a reset and triple checked all the settings. There are good torque and PAS/cadence readings but always 0 watts. Any ideas? The motor worked fine with v18.2 but had extreme backward resistan...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have tried version 19 beta3 which fixes the backward resistance but now with v19 beta3 the motor never applies power when pedaling. I am hoping someone will have some ideas on this. I will reflash it with 18.2 to make sure it still works with that level of firmware just to make sure something els...

Thanks for the update Casainho! The 850C is looking great. Can't wait! A fellow from TS tells me that APT can produce the 850C with the proper firmware. That is a version of 850C for the stock firmware. It won't work with the open source firmware. The version Casainho is working on will have many t...

The 850C does have a wattmeter actually - for the TSDZ2 version. FYI - the 850C is actually carried by other companies as well :wink: some had it made a while back and kept quiet :D
Thanks for the clarification Eyebyesickle. Eco Cycles rocks! Can't wait to see what you do with this stuff!

Hi ! Nice project!!! I routed my rear brake cable through the motor. it is enough place. but rear derailleur cable would also match (brake=6mm and Shimano SP41 is only 4mm), but the real problem is the angle of the routing - its too much. Its a Frey AM1000, but might be the same issue here. I chang...

I think I did not release 0.19, I think. I want to review the commit of Buba and maybe, add the code to disable the PWM while resting.
I have the coaster brake bike back in the shop and will do the tests you asked for. Need to disable PWM with wheel speed >0 for the coaster brake.
