For those who might be interested, here is also the story on how I got to decrypt these fields: https://www.creationfactory.co/2021/12/reverse-engineering-laotie-ti30-scooter_14.html Cheers

Another update: figured out the encryption of the only field in the frame sent by the LCD which was yet to be understood. Updated the python scripts for allowing the decoding of this field. It turned out that this field (byte nr 5 from the frame sent by the LCD) encodes the current gear. It...

Fyi, I have also added a bit of further discussion around this reverse engineering of the protocol in this blog post: https://www.creationfactory.co/2021/12/reverse-engineering-laotie-ti30-scooter_11.html The scripts have also been updated to decode a few more fields, and I am now accurately...

Thanks @amberwolf, That is interesting. I saw the project, in that case they use hardware that is based on the very popular STM32 micro-controller. Supporting FOC in the same hardware is an awesome improvement. In my ESC, the hardware seems to be slightly more "exotic" in that respect. The LCD...

Hello raxrip, Nice digging work, it served as a precursor to my own investigation on a similar LCD that is installed in my Laotie Ti30 scooter. I was able to do several findings which I believe are also useful for decoding this QS-S4 LCD. I have created this post detailing some of the work...
