Ok, I erase LCD 3 program memory, data memory and option byte. Can be this problem that I do not have right option bytes?

Or you try to get help maybe from Stancecoke or I can only help you on Linux.

Do you plan to show the temp on lcd3? I can order one for you if you will implement NTC10K, KTY 83, KTY 84 sensors. I don't use any display. Perhaps Casainho can implement it in his custom firmware for LCD3. Of course we have to send the temperature data from controller side. I can implement it, if...

I know and understand your implementation. Perhaps I will copy it, if the first useres report burned mosfets with my solution... :wink: The control loop doesn't allow high gradients in duty cycle anyway. The biggest risk is to block the wheel while braking hard at riding, so you should avoid this. ...

Hi, I follow your project and it is amazing. I was buying TSDZ2, LCD3 and ST programer. Now I like to upload code and can' t. First problem is when I try to compile alway return error. I used stancecoke instructions for Windows. What can I do. Error message: new log session date: 06/30/18 time: 23:...

sdcc - compiler : stm8-binutils-gdb claims that " From version 2018-03-04 sdcc and openocd for stm8 does no longer have to be patched " and " The latest version of SDCC is 3.7.0 and support debugging with dwarf2 format ". So I suppose I'll be needing v3.7.0 then? Or does stm8-binutils-gdb already c...

I just updated my fork with code for phase current limiting in throttle mode (by the formula phasecurrent=batterycurrent/dutycycle) That seems an incorrect implementation because: 1. battery_current has a big delay because of the low pass filter on hardware and so that code will not be able to dete...

Sorry. I missed it, silly of me. By the way I want to connect controller LCD cables to Arduino. I am going to connect Green to RX, Yellow to TX, Black to Ground, Red to Blue, and maybe Red through resistors (voltage divider, something like 110k to 10k 1:12) to analog to read voltage. Anyone done th...

Trouble is I'm now into the difficult surface mount stuff so this controller is now consigned to the 'spares only' box. Good job these things are so cheap....

Yes, being cheap and widely available are some of the strategic points to choose this controllers!!

Now developing our firmware for TSDZ2, today I implemented the wheel speed calculation. On the LCD3 side, the user now inputs the wheel perimeter in mms (on the video I setup 2070 as it should be the value for my 26 wheel). As you can see, there is a good resolution in speed, no more jumps of 3km/h ...

Well, now only to understand how the system works. You know, with the information others did share and some more investigation, I now fully control all the information that flows motor controller <--> LCD, you can see how it works here: https://github.com/OpenSource-EBike-firmware/Kunteng_LCD3_firm...

I can see the serial communication from motor controller to LCD. I've used my poor man's cable connector and Arduino Uno.

And what is your plan?

casainho - just about to test the WH feature on the LCD3 (...) Excited to try this out - will update! I am about to break the compatibility of LCD3 firmware with original improved firmware. I left the firmware that compatible firmware on this branch: https://github.com/OpenSource-EBike-firmware/Kun...

casainho - just about to test the WH feature on the LCD3, here's a short writeup of my understanding of the secondary menu (quickly looking at your code markups) Hold POWER to get into the secondary menu 0 state (UP/DOWN to disable (0) or enable (1) WH display in lower right-hand corner) POWER for ...

And here the information about that 3 values that we can change on EEPROM, since you didn't write about the first one: Here is the data of each byte: • 1. byte value: battery min voltage (need to divided by 2.5, like 0x4E → 78; 78 / 2.5 = 31.2; battery min voltage = 31.2 volts) • 2. byte value: bat...

LCD3 firmware just got the very first contribution from another user - Karl Szmutny from Munich, Germany, submitted the implementation of offroad mode for the LCD3!! Please see here the description of how ti is activated: https://github.com/OpenSource-EBike-firmware/Kunteng_LCD3_firmware/pull/3 I th...

About new features, Do you, with the new firmware connect the bluetooth to debug the firmware? Where do you connect the Bluetooth module? Can we connect the module to the speed sensor cable ? Maybe the best way is to connect the bluetooth module in the same cable of the lcd3 dispay? Yes, must be on...

I have a question if you guys don't mind. It appears really simple to remove the side cover and access the wiring for the controller (2 min job). Is there any way to connect the link tool directly to the wires or connectors inside the motor housing? Yes, follow the cables that are wired to the boar...

But they are totally different in hardware between that models, unlike the KT controllers. are you sure?! The housing is different of course, but the pinning of the processor will be the same I think. I remember to look at some information that pointed me to that. But since is harder/expensive to g...

This is my current plan for next 2 features on LCD3 and I remember some of you guys asking for 1.: 1. Adjust the number of minutes for auto turn off the system 2. Adjust LCD backlight for night and day modes Please read the details of each point here: https://github.com/OpenSource-EBike-firmware/Kun...

Hi, I know some people have had problems with '52v' units not actually being 52v etc... I drafted up a little programming manual for someone, maybe more people can get some use from it. It goes from making the programming cable, to installing and configuring the software (for windows) to the actual...

Are there any more powerfull lishui controllers?

They have several 48V 500W E-Bike-controller also. For even more power they have motorcycle-controllers up to 5kW.

But they are totally different in hardware between that models, unlike the KT controllers.

Thanks for the reply. Interesting thing is that when I apply 48v to the unit from my dc power supply it reads only 2-3 bars so I assumed that means it's a 52v unit. When my LCD3 shows 48V, it also shows that 2-3 bars. It needs the 54.6 volts to show the full bars. My TSDZ2 is configured for 48V bat...

I also did install a TSDZ2 (36V motor and 48V battery pack) on the new 24'' wheel mountain bike, for my 8 years old son. He loves it, "so fast" he says :-) :) I guess with an 8yr old on a lightweight bike it will probably do 25-30mph without pedaling :) I wish they had these when I was a kid. I had...

casainho: That battery bars cycling is normal and is a protection for when you power up the system and battery is over charged. This protection is needed other way the wheel would start running without you pushing the throttle and this would be dangerous!! This is protection is needed because of re...

Hmm, strange. Which fork did you use? What max current did you choose? Can you post your config.h? I never tried more than 6amps yet. regards stancecoke I'm using the current casainho fork of the master branch. You may be on the right track with max current, I've just remembered I did play around w...
