Re: opensource 3d printable electronic shifting?

Hi geeksville, I'm very happy to see this project! I think that a nema8 is good choice https://it.aliexpress.com/item/33022432482.html?spm=a2g0o.productlist.0.0.315d477baV5rO7&algo_pvid=b4dd4c28-c95e-4215-a757-f12d817c423d&algo_expid=b4dd4c28-c95e-4215-a757-f12d817c423d-24&btsid=d5b5b17a-1d7f-42c2-9...

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

Torque sensor full calibration I decided to use 8 points and it seems to work. I don't know if there is a better way for the users. user will need to edit the tables values of right and left pedals (ui16_torque_sensor_linearize_right and ui16_torque_sensor_linearize_left), on the file ebike_app.c: ...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I want to investigate on my thought that in some situations (hilly journeys), the power saved by auto shift (letting the driver legs/motor work with the most adequate gear) is more than the power consumption of this sub-system. So, I rerouted/created some input/output of my KT36/48SVPR-HRD01: Rearr...

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

All this is due to the EEPROM bug. I am trying to solve this once and for all. If you want to remove all those "bugs" try this: Step 1: Go to the Configuration Menu, Basic Setup Step 2: Go to the "reset to default settings" Step 3: Hold the UP button until the counter goes to 10, the screen will be...

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

fi7ippo what type of assist have you used, power, torque or cadence? I have only read the manual ad i have not understand if it's possible to do a mix mode.... es. level 1-4 power mode, 5-6 torque, 7-8 cadence and 9 emtb I've tested the torque mode. I think single mode + emtb at the end! A trick fo...

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

Still I think that start with cadence = 0 should be an option as it is now. And it is very easy to add if you still feel it is needed after testing the 0.20.0. Hi guys, I have recently installed the brake switches bought a year ago and never installed due to lack of time, and I must say that enabli...

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

Returning to the sensor, it has a braking pulse of 0.5 seconds when the shift cable moves. There's no need for a shift sensor on a system with a torquesensor, as the motor reduces power automatically if you are turning the pedals with lower torque with your legs for shifting, as you do on any norma...

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

Seems original does not implement that shifting, maybe we could use the Bafang shift sensor but seems no cares about it on TSDZ2. IMG_20190719_222227.jpg This works perfectly in parallel on the brake sensor. I'd be curious to try it together with the Kit Archer D1X, but it costs as much as the TSDZ...

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

Street Mode is enabled by holding the ONOFF and DOWN buttons for a short period of time. This is so users can somewhat easily and discretely switch between different modes. Do you feel this is bad? hm, for me this is too easy to guess. I dont want to risk that some officers try pushing around the b...

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

I think the best way to adapt the torque sensor to the various users is: 1- Read the rest value of ADC steps during power on and add a low pass filter of one or two ADC steps (for resting value); 2- Create a user parameter that set the ADC value for a know Force applied maybe 30Kg could be a good v...

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

I am very happy that you like the idea, but I was thinking, and I believe that if it is not too much trouble, and there is enough memory space, the ideal would be to have two parameters that can be changed by the user: 1- User calibration weight available with an approximation of 0.1 or 0.5 kg (thi...

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

For calibration the torque sensor the rest value is read every time the unit is powered on, right? Yes, it is calibrated every time the system is powered on. But it is not calibrated properly in 0.19.0 and previous firmware versions. Noticed it with my particular torque sensor. So I rewrote the cal...
