I have created a detailed tutorial for hardware calibration of the torque sensor. Any feedback is welcome.

Hi, Anyone with experience in torque sensor has some ideas why the sensor does not read any change in torque? Thanks! 1. Why does the sensor value not change on force? 2. Also is there a way to simulate pedal force without installing it on motor? 3. I read the wiki but is not very clear how to do it...

Any feedback here is welcome. I already disassembled the sensor 4 times and I am out of ideas. :cry: Hello, I did a hardware calibration of the torque sensor. The sensor reads value and has not error, but it does not change on pedal press. Stays almost fix value. If i move the small black part with ...

1. Why does the sensor value not change on force? 2. Also is there a way to simulate pedal force without installing it on motor? 3. I read the wiki but is not very clear how to do it with 2 screwdrivers. 3a. Maybe someone knows better how a torque sensor works and has some ideas. 1. It probably is ...

Hello, I did a hardware calibration of the torque sensor. The sensor reads value and has not error, but it does not change on pedal press. Stays almost fix value. If i move the small black part with the magnet and hall sensor, the values change, but still on press nothing. I opened the motor twice a...

Hello,

I run into a problem. When switching the battery power button, the controller make a short beep. Pressing the start button does nothing. Anyone else had this problem?

Thanks!

It would be useful to have this info on the brake page in wiki. Thanks for the clear answer! I need some help from users with e-brakes. I did not find the info on wiki. I had to buy a new controller since mine is dead. I bought a 8 pin controller now that has throttle and ebrakes support. I use the ...

I need some help from users with e-brakes. I did not find the info on wiki. I had to buy a new controller since mine is dead. I bought a 8 pin controller now that has throttle and ebrakes support. I use the custom firmware with temperature sensor connected to the throttle, so I will use the throttle...

Hello. After about 1000 km, I have a problem with the torque sensor. At a standstill, with the pedals set horizontally without load, 192 shows once, after driving a few km 200, again after a few km 196, etc. the same is true when the pedal in a horizontal position loads its weight. Once I have 275,...

Hello, I had to buy a new controller since mine is dead. I bought a 8 pin controller now that has throttle and ebrakes support. I use the custom firmware with temperature sensor connected to the throttle, so I will use the throttle wires to solder the temp sensor. I do not use ebrakes. My question i...

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...

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...

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...

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 ...

I have created a pull request on Buba's repository so this important fix does not get lost.

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...

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!

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 ...

Long time, no buba...

Glad all is well! Can't wait to try some new things!

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 ...
