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

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

Re: Problem with torque sensor!

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...

Re: New "TSDZ2 Torque Sensor Central Motor"

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,...

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 installed a new torque sensor.

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!
