Hi,
Regarding Blinking 1,
I see the use of it , but also feel the problem in traffic light, or when you just stop and talk with friends,
My saddle is quite high, so my foot is restng on the pedal when I stop.

I am wondering if it is possible to
- have a threshhold for torque before it reacts So it can be possible to rest the foot on the pedal (Value 12.3 50 may a good starting point)
- maybe have rhe timeout at 10 s and the cominng back 2 s?

Should I ask for it in Github?
Can you please explain what is the practical use of the “Blinking 1” ? Is there a nonstop re-calibration ongoing which needs it ? To me is the most annoying feature of v19 :)
As I understand it, it is a safty feature for-
-Saving the blue gear , specaly on high volltage , one may damage the gear when standing on the pedal and holding the bike with the brakes
- when you have a crash, and a pedal may hang somewhere and the motor is pushing against this hanging pedal, a driver in between .
right?

Both issues would be solved with a solution above in my opinion.
For my setup with a relative weak 36V batterie , I cannot see the use of this feature.
Yes, that feature is to protect against possible unintentional locking of the pedals.

The feature was working well before but on last beta version has an issue. For the ones that can't live with this issue, please use the latest stable version until this is corrected.

Sorry to say, but I am on last stable (18.2) comming from 10.x but this funktion as it is in 18.2 may make the bike more save for some riders with high power but is not nice with my way of riding. I never felt unsafe with older versions.

What do you think about my ideas for iprovment?
Alternative can you considre to have a flag to switch it off in configuration?

It is supposed to work well, to ignore if you keep foot on pedals when assistance startup without pedaling is disabled. If it is enable, then you should not keep the foot on the pedal or at least keep keep braking if resting the foot on the pedals. What is happening to you?

I am holding the brakes, (Old Hydraulic Hayes 9 DH breakes with 200 disks, but not compatible to sensor) of course!
But my foot is just resting on the pedal without pushing. Thats why I am asking for a threshold!

I can confirm that magnetic brakes (8$ on pswpower) are really beneficial on this motor for various reasons, for instance unintentional start at traffic lights due to foot on pedals or some other failure.. it acts as a switch that disconnect the motor.
I have two on the MTB connected to the LCD3 and one (home made) connected to the city bike directly on the back of the stock VLCD5 display.
It's a bit more complicated to connect them to the LCD3 because you need to splice and solder the wires into the main cable from display to the motor, easier on the VLCD5 because you connect directly on the ports of the display.
Anyway I strongly recommend to install the brake sensors, specially on a MTB also to prevent blue gear stripping.

Interesting I have been using the release.bat batch file from within the src code zip files here https://github.com/OpenSource-EBike-fir ... e/releases to compile the display and controller source into .ihx files and the batch file it simply copied them into .HEX fires using a simple file copy and rename, so the resulting files were smaller than the released .HEX files. that explains things!

I updated my releaste.bat file so changed the lines...

COPY .\src\controller\main.ihx %release_folder%\TSDZ2-v%new_version%.hex
to ...
packihx .\src\controller\main.ihx > %release_folder%\TSDZ2-v%new_version%.hex

and

COPY .\src\display\KT-LCD3\main.ihx %release_folder%\KT-LCD3-v%new_version%.hex
packihx .\src\display\KT-LCD3\main.ihx > %release_folder%\KT-LCD3-v%new_version%.hex

Now they are converted using packihx and are the correct size.

Do you think the release.bat file should do this, or does it really not matter?
Like I say the existing smaller ihx files renamed to .hex files flashed fine using ST Visual Programmer
I have not given it much thought until now. After your testing this certainly is interesting. What I think(!) packihx does is to ensure the structure is valid and remove unnecessary data. IHX is a database file. It seems to be possible to just COPY from .ihx to .hex without any problems, at least in our use case this is as valid as using packihx.

But it probably is best to use packihx as it is developed for a reason. I have always used it in my scripts instead of COPY. The bat files could be changed and included in my next pull request, and of course credited to you, perryscope.

Hi buba,

i have one request for next release(s) which i find interesting for all users - trial/emtb mode like on bikes with brose or bosch motors. It is described here:
https://ebike-mtb.com/en/emtb-mode-bosch-cx-review/

To use trial mode user needs to set assist to factor >10 on one of assist levels and in the code on motor controller side it will look like this
if(m_configuration_variables.ui8_assist_level_factor_x10 > 9) then ->trial mode where
ui16_pedal_power_x10 <10% -> ui8_assist_level_factor_x10 = 0.3
10% < ui16_pedal_power_x10 <15% -> ui8_assist_level_factor_x10 = 0.5
15% < ui16_pedal_power_x10 <20% -> ui8_assist_level_factor_x10 = 0.7
and so on

This way this mode can be set up freely under one of assist level from 1-9 and final setup could looks like this:
assist level 1 - eco mode- let's say factor 0.3 for assistance,
then assist level 2 - trial where assistance depends on pedal power and varies between 0.3-3.2x
and assist level 3 - boost mode - 3.0x,
assist level 4 - 3.5x
and so on

For brose motors assistance in trial mode looks like on the screen (Eingabe - torque/pedal power and Leistung - % of motor assistance level which is our power motor factor )
In every review of bikes with this motor one of best thing that is always mentioned is the ride feeling that is very smooth and natural in this mode So having this feature can make our bikes closer to the 5000 USD and up machines ;-)
Interesting and can't help but wonder how this feels. Would definitely be fun to try out! It is always possible to make a simple prototype version in the future!

Want to start a climb after pusing the bike, I was two times not fast enough to turn the pedal when going onto the bike (not usng brakes).
Please tell me where is the code for this? , maybe have to fork to make tests if it is possible to make a "min Value" for the torque (maybe 10%)
I know, every rider is different, for me this is quite anoying,

I removed the motherboard of the controller without damaging it because I want to mod it replacing some cables. If someone is interested I'll post some pictures.

Can I use the connector from the lights cable to solder it to KT-LCD3 and connect to motor? I don't want to cut the connector from the motor to solder directly or cut off the VLCD5 connector.

Thanks, found out. Guess I will just butch the connector to reuse the pins and then plug it in.

Edit: made the connector (used this picture, hope it's correct: download/file.php?id=239409&mode=view)

I'll use this post to make a wiki about extracting the motherboard of the controller.

first, remove this 2 screws
Image

in the bottom there are two crosshead screws that in the photo I already removed
Image
go back and remove all screws
take a screwdriver or something of similar and begin to remove the liquid rubber that seals the hole where pass all cables. I suggest to remove it well otherwise the cables will not pass.
It's better to remove cables one at a time. I removed the battery cable to last.
Now the controller is free.
Remove in the side of the controller the screw that hold the sensor (this photo is on loan eheh)
Image

Now it's better to use a tool of plastic or a piece of wood to remove part of sealant.
Remove well the sealant that cover the mosfets and a screw in the bottom. This photo is for reference.
Image
Now with a tool pass it all arond the controller. It goes well a ice cream stick.
This part is invasive.
take a hacksaw, or a dremel, it's better a hacksaw because you have more control.
cut part of the shield. do not cut at the height of the mosfets because it is a bit more difficult to cut and to remove the board. it is better to cut lower.
The side to cut is opposite to the one where the sensor was screwed in. So you have an access to the lower side.
Image
With pacience, leverage with a tool to lift the block of sealant. Don't damage it, just detach it. it will come away whole.

About the connection,it is impossible to remove them without desoldering, Before desoldering, remove all sealant, also passing a cotton wire under the connections. Apparently, they look like ports to be disconnected, but instead they are soldered connections. So don't try to pull them. The cables near the ground wire are difficult to desolder. The rest is easier. There's need of a soldering iron that reaches high temperatures. I used mine at 400° using also the soldering flux. At 300° they don't come off.

Hello, Just wanted to ask the status of the various development.
As far as I remember the v.0.19 beta was about to turn to the stable version, as well as the LCD3 updates.. but no news in the last weeks from the developers.

And what's the status of the other displays (850c and 102)?

Thanks a lot!

I personally I am not finding time to work on the firmware. Maybe because this year, during this nice months, I am being riding on mountains, etc. On winter I tend to ride less and then I have more free time.

This is what I know:
- LCD3 firmware: I think Buba is available to correct bugs and there are no planned new features (even because the programming memory is full!)
- TSDZ2 motor controller firmware: the big improvement from latest stable version is the removing of motor resistance when pushing the bicycle backwards. In the process, other bugs did appear and they need energy to solve them. I think Buba will try to help on this.
- LCD 850C firmware: I did not working on it lately but I think I should make a version with fixed numeric fields and graphs, as adding options to customize variables will take s lot of work. For the graph, I want to make it show the human pedal power. For numeric fields, for sure I want pedal cadence, motor power -- what should be the other 2?
- LCD SW102 Bluetooth and mobile app: I think there are about 4 developers working on it, where 1 is specifically developing the Android mobile app.

Yes, I am being riding with my family and we love it. And now about one of the most dramatic experiences we had recently. While we were riding, we found a Smart car overturned and inside an old woman - that was on a trail that almost no one pass. We found at 14h but the woman was there stuck since the previous night. She was fragile and gave her water and after my sweetened juice that I; always carry with me on my bicycle trips. The firefighters and police were very fast and the woman was ok, everything went well in the end.
