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

And another problem: after displaying another value (e.g. temperature) the current speed is often not displayed for a while. Instead, the display shows only "0.00" for some minutes. If I recall correctly that is a feature. Since the speedometer is used to display values, the odometer gets wrong val...

Re: Tsdz2 firmware open source adapted to vlcd5

I was under the impression the configurator was initially made for configuring the kuteng controllers with open source firmware. I have no idea who started writing it and if it comes with a GPL or other license. So, what is so special about Marcoq his configurator that shouldn't be revealed to the ...

Re: Tsdz2 firmware open source adapted to vlcd5

Stancecoke, I understand marcoq did not agree to publish its source code for whatever reason, and that was clear to me since the beginning after the early discussion between him and casainho, plus the popup at the interface startup. Any chance for you to remove the source code from your repo? As al...

With the guide on, it's too tight for the TSDZ2 to slide in and fit the way it should. But I can't remove the guide either because I need the rear derailleur.
So, what do I do?
Replace the wire with full wire guide from the shifter, then route it above the bb-shell.

Re: New "TSDZ2 Torque Sensor Central Motor"

Could it be that slipping of that blue gear could be a feature too, to save the blue gear if there is too much stress on it? I don't think so, if it is, it's only made for > 0 celsius. Because I only had trouble with it during -10 celsius or colder, and it would slip with minimal torque as well, ev...

It does not happen often. Maybe once every 60 power cycles. Possibly related to adjusting assist level while screen is still loading, as last two times it happened within 30 seconds of starting my commute. Maybe i'm somehow turning on walk assist or something, not sure how to do that. Does the km/h...

Re: Tsdz2 firmware open source adapted to vlcd5

Modified the firmware to motor amps control and results are nice. Motor feels more connected, which means it follows your input even better. Downside is that the more the motor follows your input the less you recognize that the motor assist you. Especially on the lower levels. You need to switch of...

Re: Tsdz2 firmware open source adapted to vlcd5

Just a warning. Twice now I've had my bike continuously accelerate after i stopped peddling. I believe this to be a software glitch, as bike worked fine once power cycled. I do not have ebrakes installed. They might have helped me stop the bike instead of having to stall the motor with my brakes wh...

Do you use three o four cables to update the firmware? It's possible that you corrupt the firmware with only 3 cables....
So it's confirmed by others with corrupt firmware that garbage data can brick the VLCD5?

Re: Tsdz2 firmware open source adapted to vlcd5

Flashing the firmware does not write anything to the VCLD5. Fairly confident there is a problem with your display, or broken data wire. I know we don't write to the VLCD5. What I meant was the feeling of weird coincidence. I run the marcoq-firmware for months without a problem, and the new version,...

Re: Tsdz2 firmware open source adapted to vlcd5

Did you install a temperature sensor(possibly incorrectly?). Someone else had the wrong wiring for the temp sensor and their display looked like that. Try reconnecting main cable connection to LCD, might be bad connection on data wire. Check for damage to the main cable wire. Others have had succes...

I also noticed that there are 3 strange inputs on the back, does anyone know what their purpose is?
If I recall correctly the ones to the side are brake-inputs, and work on all versions of TSDZ2, the middle one is throttle and only works if you have the 8pin-version of the motor.

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

I may be completely out of the loop here, but why do we need the human power to be accurate? It seems that all the TSDZ2-units have differently calibrated sensors, and perhaps the stock firmware is compensating for that (undocumented eeprom-data?), perhaps it isn't. Couldn't we include a calibration...

Has anyone tried that 100mm or 120mm adapter axle from futurebike in Italy. I’m interesting in building a fat cargo bike but it will need the longer version of the pedal axle.
I am running a 100mm kit on my fatbike (non-cargo). It was easy to install and works as expected! :)
