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

Running into an issue with 18.0 that I'm hoping is just a configuration problem that you guys can help out with. Assist is working properly from a stop, but then 3-5 seconds later it cuts out. Almost like I have boost turned on (I have boost disabled) and when boost fades out there is no power ther...

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

I have to be more precise. A short circuit occurred when the speed sensor cable was broken. For a moment the engine stopped and I saw the speed of 56kmh on the speedometer, even though I was almost still. Then I unplugged the connector and it all started again. So in fact a short circuit between th...

Re: Open Source Firmware Tutorial

A lot of people, including me, found upgrading to open source firmware difficult, because the information is spread out over two threads with over 200 pages between them. I also needed the excellent github information and jbalat's videos, and those resources weren't immediately clear to me as I wen...

also find I am accidentally entering the motor power setup option by mistake.

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

As some may know I have been working on fixing some reported bugs on the 0.18.0 beta 1. Wanted to share 0.18.0 beta 2 but there is a problem... Okay... So the program memory on the STM8S105 is 32 kbytes (flash). Seems large enough? Well we now have seemingly exceeded it with the 0.18.0 beta 2. The ...

hi buba Before I go ahead flash and test this beta can you confirm that the controller firmware hex will work on both 6pin and 8pin controllers (I have 8 pin) and although the firmware is called higher cadence it also includes your walk assist and virtual throttle betas. Thanks Hello! Yes, it is su...

Here is my fork and the branch is called "higher cadence".

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

Could it be problem in 52V and 750W motor for firmware does not work? I don't understand. I have 36 V battery and 250 W motor. I've been commuting now two days, not long trips but v17.0 works very well. And it's so good that I'm not going back to stock firmware. Feels just like I have bought new mo...

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

Did anyone try to flash back to stock from the flexible firmware? I have a 36v motor and a 52v battery, and trying to get back to stock with the 52v-profiles from eyebsickle, left me with the controller thinking the battery is empty. So it wont run. But I used the same profiles before the flexible,...

Excellent news Buba, I was only looking at the LCD3 manual a few days ago and thinking it would be great to have all its other functions enabled but not expecting anyone to do it. Just a shame it does not have a battery to store time/date. As for walk assist or any other function that rotates the wh...

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

Is 17.0 the wrong file? It loads but the LCD3 display will not flash up afterwards I've had to revert back to 17.0 beta 5 The file size looks too small, smaller than 16.0, buba's 16.1 and all the 17.0 betas It is the same size as the controller firmware too and LCD3 firmware is usually larger. Also ...

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