Re: New "TSDZ2 Torque Sensor Central Motor"

Hi all im looking for a way to troubleshoot this issue. I flashed the tsdz2 and lcd3. Got my battery today, connected everything for the first time and the LCD3 turns on but theres nothing meaningful. Just fully lit, displaying all characters. I have the 4-1 cable and followed these wiring diagrams...

Re: New "TSDZ2 Torque Sensor Central Motor"

I downloaded TSDZ2_Controller_vM0.16.D_and_TSDZ2_Configurator_Beta_0.2.0 from github and it includes the GPL3 license and source for the motor code. I did not see a warning on the JAVA configurator so maybe this isn't the latest. I think it is a grey area re the configurator being not under GPL. Ce...

Re: New "TSDZ2 Torque Sensor Central Motor"

The TSDZ2 will not fit out of the box on the bullitt, removing material on the motor is needed. I have a dremel so i will give it a go. My intention is to also put a rubber damping between motor and frame to reduce noise transfer. (BTW; did anyone even try to mount it motor above the crank on a bul...

Re: New "TSDZ2 Torque Sensor Central Motor"

I will convert my bullitt to TSDZ2. One of my dreams is to buy the bullitt frame and install TSDZ2 on it. I hope I will do it in 1 or 2 years, depending on a new baby in the family ;-) 1) The TSDZ2 will not fit out of the box on the bullitt, removing material on the motor is needed. I have a dremel...

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

So this is what I am focusing on now. Will effectively use every cadence sensor signal change as they are verified to be equally spaced and then we will hopefully get twice the resolution. Note that on wheel speed sensor as also on pedal cadence, the calculated final value needs at least 2 signal i...

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

Successfully flashed my first 850C. Very cool. Nice work Casainho! This is the new first choice display. Thanks and although the firmware needs a bit more work, which I plan to do on next days, I already put a recommendation on wiki for this LCD over the KT-LCD3. Maybe this is not fair as KT-LCD3 f...

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

The DPC-14 and 850C are in fact the same. I have confirmed this with the manufacturer. The DPC-14s are the ones manufactured specifically for Bafang and sold by Bafang. The 850C is APT, the manufacturer's, model number. The issue is the age of the display as there have been many hardware and firmwa...

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

Hello, I solved it this way. The five-pole Bafang plug now goes to the JTAG. Unfortunately I already sealed the display with silicone, otherwise I would have taken more pictures from the inside. Unfortunately I forget this again and again. Connector.jpg I drilled a hole for the motor cable. drill_h...

I would prefer open source software, but this is my friends bike who is not technical at all and bought it used, I really don't want to brick it. Just trying to help him out as the battery the guy sold him with it is too high of voltage. I guess i could take the LCD apart it apart to flash it, but ...

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

I thought that may be the case. I did get this screen 2nd hand some time ago (dec 2018) as a spare for my BBS-02 setup so the original seller is unknown unfortunately, but I have tried to contact them in case that can share where they purchased it from. My guess is its an earlier version but it was...

Re: TSDZ2, how do I know I'm not wearing out the motor?

I recently installed a 52v 750w TSDZ2 motor on my road bike. I know that riding in too high a gear will eventually wear the motor out. However, how do I know this is happening? In other vehicles, you can tell if it is overworked. You can hear a car's engine struggling, or automatic transmissions sh...

Does anyone know how to change the max voltage on the 850c version of the TSDZ2. If I try to change these values, is it likely I'll possibly brick my controller?

Why don't you install our OpenSource firmware on your TSDZ2 and 850C display?

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

Looks to be a different PCB layout compared to your photo, and unfortunately there is something on the chip obscuring some of the lettering. This is an existing photo I had so i will take it apart later and try to remove the mark, I think its just black marker. That board uses the STM32F103RCT6, wh...

Re: New "TSDZ2 Torque Sensor Central Motor"

If the derived source is available this is OK. Is it? Also the usage of the term proprietary seems wrong. It isn't, it is GPL3 open source. Selling it is OK - as long as the derived source is provided and the GPL licensing terms are not removed. I think the sources are not available, at least I cou...

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

I've downloaded the proper software and files and exposed the programming pads. The pads are quite a bit narrower than the LCD-3 connectors. Are you soldering pins to the pads or just bending programming pins from the st link five wire into a narrower width? I was thinking to cut the corner out and...

That's odd. But glad it's working for you. Would you mind uploading a screenshot of the stm32 st-link main window. Does it look like the bytes are correct for the .bin file. Also did you erase from stm32 st-link or was the screen already flashed? Target Chip erase Yes those are the steps I followed...

After some time with new version of firmware, it looks like the "no power" issue is still there, but not as pronounced as before.
