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

Just a thought. Is holding down the plus button used for anything? The minus is pretty much a universal standard for walk assist. Since cruise control is a new feature, how about using the plus button so they don't conflict?

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 went through the ES threads.

Here is my attempt at a comprehensive tutorial for installing Open-Source firmware with KT-LCD3 and also flashing stock firmware. It doesn't cover everything. I haven't tried marcoq's method of installing OSF with the VLCD5. I didn't cover installing a temperature sensor. The waterproof connectorized cable is for an 8-pin system, etc.

I think it is pretty complete and good for someone new who has never before dealt with connecting to embedded processors. I wrote it before I became so comfortable with the process that I would glide over things that would not be obvious to newcomers.

Revise & re-post as you like. I hope it works for others.

I think your first sentence may be wrong though as I believe the 6 pin VLCD 5 does have brake inputs and the only difference between the 8 and 6 pin versions is that the 8 pin version has an external throughput for a throttle down the two extra wires.

I am going to order another TSDZ2 for my partner and wondered if I 'share' one display between the two motors. So I flash LCD and then flash each motor, but then on one bike go back to using the old LCD once settings changed?

dont thinck it match ...
for vlcd5 use, go to : https://endless-sphere.com/forums/viewtopic.php?f=30&t=98281&hilit=TSDZ2

i use 2 tsdz2 motor, one with open source firmware " standard " ( with kt-lcd3 display ), the other one with VLCD5 and modified firmware from marcoq, all works fine .

it's the same for me i'm testing my new bike whit tsdz2 48v and firmware .18.02
i have also a turbo levo 2018, and it's incredible, i really prefere the bike whith tsdz2 i get over 850w on the display and the shock absorbers are really better on this bike even if old...
I thought about getting a "second bike", but it came too well, in the last days I use only this one and the turbo levo is still, I almost wanted to sell it
the only thing that really keeps me is that I do not know if the poor engine will be able to withstand my weight for a long time

Thanks, I'll revise. Since I have 8-pin that's what I know.

Hello casainho, I saw that you are interested in transferring your software to other displays and I would like to ask you two questions:
1. are you continuing to work on the LCD5 display?
2. I found on the site of the Italian seller this color display that looks just like the bafang 850C:
http://www.future-bike.it/shop/kit-di-trasformazione-3/display-vertical-a-colori/
  if it really is he definitely solves the problem of cutting the cables for the connection to the engine that you think?

Click to expand...

1. yes.
2. I don´t know... but that one is very expensive!!! You can buy at half of that price on Aliexpress and I guess that with adding costs for taxes will be lower than doubling the price.

Hi Casainho,

I was wondering if you had any guide/workflow for compiling the ColorLCD code for the 850C. I have an 850C ready to be flashed but I'm struggling working out the process to compile. I can see the make file is not using sdcc to compile, and looks to be only for a Linux platform, but I'm not sure on the pre-requisites needed?

I also found a nice place to get the programming pins out without compromising the water resistance much...

This my first post so I'm new to this but impressed with all the great work you guys have done - so first many thanks for all the great work you guys are doing - very interesting.

I was wondering if anybody can assist with a strange problem I'm having, once programming (with v18.2) I have what appears to be a fully working KT3 display but no power assist from the motor at all (same results with the older firmware versions too).
My bike is running 48v 750W with 48V 12.8Ah Li-ion with LG LGGBMH11865 cells and works fine with VLCD5 display, it is 6 pin with no temp sensor or throttle installed. As I said it runs fine as stock and with the eco-ebike 'upgrade' hex files installed but like most people the cadence issue was why I started to look for improvements. I have bought and set up the KT-LCD3 and using a ST-Link v2 (not a clone) with the 'homemade' suitable cables I can program both motor and display without errors (and go back to stock set up too) so I don't think issue is with the programming or cable side. Where I've got to is that everything in the display configuration appears to work fine and the setting configuration data can be entered and is saved ok; the functions all appear to work on the display e.g. assist level changes with button press, off road mode toggles on/off , same with walk assist etc .... only weird thing with the display side is that I have the temperature cell (bottom right on the display) always flashing 0 deg C even though the motor temp control feature is disabled (no temp sensor installed) and is still flashing if I disable the whole temp display setting (sub menu 6.0 set to zero to display nothing in that field) ....... apart from this strange temp display issue the main issue is that I have absolutely no assist from the motor even though the motor controller appears to be taking the hex file and verifying OK. Using menu 12.3 I can see the torque sensor is working when I apply torque to crank but I'm getting no assisting in any mode or with walk assist or anything ? Can anyone of your wonderful people suggest what to check next ? The only thing I can think off is maybe I have a faulty motor controller or something ? I'm an experience mechanical engineer but like most of us older grease monkeys we need help with the electrical side
Thanks in advance and keep up the great work.....

You description of problem and tests you did really help to understand what can be happen.

I guess it is the max temperature limit that is disabling the motor power -- it does that. The thing is: are you sure you did reset the defaults values and are you sure the motor temperature sensor is disabled on the configurations??

Thanks for trying to help. Yes I've checked and double checked that the configuration is correct with the temp sensor disabled but still no success. Could it be something to do with the option byte settings as I've read on here some other people were have different issues with the option byte set up (I have no idea what the option byte does BTW). It was the AFR5 and AFR3 fields that people were changing - what are the correct values for these fields and how do you set them as when I tried to force the AFR3 field to TM3_BK1N as suggested in an earlier post (possible if I use the STM8S105x4 setting) when I turn on the bike to check and then go back and re-read the option byte it have changed back to TM3_CH2 ? Same result with STM8S105x6 read. I'm also correct in that you should force the data memory tab to all zeros at the start (that is what I am doing - again tried both x4 & x6) which is working ok but then populated when you switch on the bike ? The data I get in row 4000 only is:
CD 28 00 0A 32 86 01 02 08 32 00 00 19 0A 32 00 .(..2....2....2.
Not sure if that helps with the diagnosis ? Once again thanks for your help.

The firmware writes by itself the correct option bytes now. It is being working for other users.

You should not have temperature blinking.

Also check you have max power configured to an higher value like at least 100W and not like 25W.

PSWPower is selling the SW102 LCD for Bafang that seems a version of the eggrider LCD, for 45€. Seems a decent price.

Let's see if we can program it....

Just put bike back again to stock and motor is functioning (as a double check) but can't get stock walk mode to work (with VLD5) even though the setting is 'on' which is strange as it was working before? Could it be a motor controller hardware issue - I may try buying another controller as a last resort? Confusing isn't it !

1. you must make sure that is not the motor max temperature feature that is disabling the motor power!! Verify again the configurations and reset to default values.

2. Not only see the torque sensor value, see also the pwm duty-cycle value when you push the pedals and rotate them!!

I had exactly the same problem. I reverted back to the stock hex file I saved before flashing. I then reflashed and immediately rest to defaults from the menu. For some strange reason, I have to reset to default after every firmware upgrade otherwise even setting the parameters manually (before resetting) results in no power. As you said verything looks but no power.

Interesting thanks for that, glad I’m not going mad ! So just to be clear you fixed it by going back to stock program tab with with stock data tab too or loaded data with zeros ? Then did you delete (zero) the prog and data tabs (hex files) or just overwrote the old stock prog firmware file with new open source file ? What did you need to do with the KT3 ? Reset that to zeroed data tab or was it ok with the saved set up data from your previous attempts when the motor didn’t work ? Sorry for the questions just wanted to be 100% clear what you did to fix it as it driving me mad ! Thanks again
