    New "TSDZ2 Torque Sensor Central Motor"

    Hi Andrea, Yes, I do the same. I've installed two thin (0.2mm) teflon rings between the coils and no more wear happened. Before I've to replace the whole torque sensor two times because the magnets fringed each other destroyed the windings... After the modification I've made at least 4k km and...

    TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.

    Hi mbrusa, I am also interested to try the sw102 version, if you share. Does the display will be update by Bluetooth? Thanks You

    TSDZ2 EBike wireless standard (like Specialized Turbo Levo) - OpenSource

    Hi AZUR, thanks you, yes, I know that. The 63v is our voltage endpoint also the motor controller has a 63v capacitors, so we cannot go over this voltage, maybe a bit less is better! How high do you charge your 15s battery? I'm very happy that @beemac share my vision, and works on implement the...

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

    Thanks You maximusdm! This is a really good news. The field weakening is the only missing things on LCD3 in my opnion. I'm available to test if you share your hex file!

    Hi casainho, I'm was far for a long time... I've no words, your work is awesome! I've some questions, please take a look when you have some time: I own a 15s battery a bit undercharge for my setup (I use BT BMS for set 4,09 maximum cell voltage, so a total 61,35v full battery) whit SW102 and...

    Hi casainho, I believe in the multipoint calibration how to edit the tab values? What is the formula for insert our weight data? Thanks You #define TORQUE_SENSOR_LINEARIZE_NR_POINTS 8 uint16_t ui16_torque_sensor_linearize_right[TORQUE_SENSOR_LINEARIZE_NR_POINTS * 2] = { // ADC 10 bits step...

    Hi Buba I'm trying to build myself the pwm branch for modifying a value, but no luck, the program exit with a warning 126: unreachable code.. I think I did something wrong because also the master branch of casainho exit with same warning when I try to compile it! Use SDCC ...

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

    Hi FedeleC, I'm very interested to Your project! Do You make any progress? I don't know if putting the servo on the derailleur is the best thing because of its weight on the gearbox. It would probably be easier to use with any derailleur if it operated the stock cable (much shorter, since the...

    Hello Buba, I've done that, some odometer field was fixed, many parameter was reset to factory default after step 4 Backward resistance is present (only at the boot, no more present after powering the motor) Odometer temp "Options 8" not show (is no important I set it to temp field) Torque...

    I've tested the torque mode. I think single mode + emtb at the end! A trick for cadence calibration: You must lock the crank to the crown so that the motor rotates the pedals during calibration

    Hi Buba, great work! :thumb: My motor is really more quiter than 0.19.0 with same configuration. The acceleration is much smoother, the power seems much better modulated. It looks like a new engine :D Take a look to backward resistance, is present in Alpha 1.0 and... Odometer says over...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    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 enabling "startup without pedal rotation" the feeling especially at the start is fantastic. Even in motion when you use the brakes to slow down and continue to...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hi Buba, I'll hope you consider to set a "minimum brake activation time" that could be fixed at 1-1.5, enough for any shift sensors if there is no time for a configurable parameter! For stancecoke, in my opinion yes and no: in the sense, it is true we do not need the gear sensor having the...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    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 TSDZ2 ... Returning to the sensor, it has a braking pulse of 0.5 seconds when the shift cable moves. I bought it for $ 20 last year on eBay. In my opinion...

    Hi shaddi, maybe 2 or 3 ONOFF click followed ONOFF & DOWN for a while, or 3 ONOFF followed by long DOWN (more easy to do specially in winter) could be a solution. You can also choice to switch the mode only if You are on a specific Odometer submenu when You start the button sequence! I hope to...

    Hi thineight, yes the motor still assists for a little, but I don't think is really a "kick" because forward your legs in the natural direction it is rather like an inertia of a flywheel sensation. I think the coster brake version do the same because has not freewheel on crown! In addition, you...

    Wow, a lot of work!! Very good job! I think that if you not use the cruise function as me and many others, you can safely remove the clutch bearing and use an thickness of aluminum keyed! This paired with along with your lightening solution would save a lot of weight :thumb:

    Hi Buba I saw the 0.20.0 wiki, wonderful, You have make a epic job :bigthumb: Is it safe to compile and test? I read a bit the code and maybe I don't understand well, but on src/controller/adc.c says 64 // read ADC torque sensor value 65 uint16_t ui16_temp =...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hi Dameri, maybe I didn't express myself correctly! The fact is that to calibrate the torque sensor (assuming it is now linear) we need at least 2 points. The first is the value at rest detected during power on, we must enter the second which apparently varies from sensor to sensor. Now, we can...

    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...

    Hi Buba, I think that Casainho is right, the two bolt are the key, but for adjust the position of hall sensor we have to do a micrometrical movement on sensor. I try to explain me better: before adjust the hall position I was in this situation: Rest ADC value: 52, Maximun ADC value: 96, so a...
