Re: TSDZ2 open source firmware only for KT-LCD3 (v0.19.0 / v.0.20.0beta1)

Hello, Here is the pull request I did starting from Buba's code. It has the overrun fix and an additional fix for torque sensor with minimal value smaller than 100 so it does not give torque sensor error. https://github.com/leon927/TSDZ2-Smart-EBike/pull/2 You can build your binaries from my develop...

Re: TSDZ2 no longer works after disassembly

hello, I recommend that you post the problem on vlcd custom thread. With lcd3 you have a diagnostic screen where you can get some hints, but in this version i cant help. I had you similar problems in 2 situations: LCD cable crushed and power cable crushed. In both cases the ldc started but the assis...

Re: Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

Hi mbrusa, I plan to add the overrun fix to the LCD3 version. LE: I noticed in lcd3 thread taht you already did it :). But my question still stands. I noticed that in case of STANDARD_MODE there is // for overrun problem ui16_cadence_sensor_ticks_stop = (ui16_cadence_sensor_ticks + (ui16_cadence_se...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hello guys! I have the same problem as Aja and Maximusdm. I have the ST link V2. When I try to connect to my XH18 unit (through the 6 pin cable, not directly on the unit, recpecting the connection sketch), I have the same message: "please check the swim cables etc..." on the STVP program (STM8S105x...

Re: TSDZ2 mid drive and 850C and SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

In sum, you need to give way more details of any issue you found so it can help me to understand and together we can workout a solution. I will rephrase. Let me know if you require more info. Torque sensor read idle is 35 units. With the unmodified software I get 2- torque sensor error and the moto...

Re: TSDZ2 mid drive and 850C and SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Hello, I installed a new torque sensor. I calibrated it but if I set it around 110, the standby value is increasing steady in use until it reaches max torque sensor value or the range is max 30 units. In this case the motor no longer engages. I managed to make the value stable but the value on stand...

Of course I will also put the source code, I am preparing the description, I seem to have been clear.
Thank you for taking the time and effort to add the change also to LCD3 version. This is highly appreciated!

Re: New "TSDZ2 Torque Sensor Central Motor"

Hello, I just replaced the torque sensor and performed the manual calibration. The 2 bolts on the sensor are well tight. I set it as it shows 125 units on standby and a max of 275. The problem is as I use the bike the standby value increases with each use. Now it is at 230. :( I did this process 2 ...

Really appreciate the answer! Can you please post some pictures with the custom tools? My problems are now only with the pull/push of the sensor to the frame. Hopefully this is the part of the puzzle you are missing, I worked out how to get the torque sensor out with the image below from the repair...

Hello, I need some ideas from people who installed/worked on the torque sensor. SO far I got the service manual from casainho and I have some clues. I will try to create a tutorial after I have a way of putting it back. How did you removed the torque sensor from the frame? I mean the actual torque ...
