Adapting display to motor controler

[Thomas M]

I have a working KT-LCD3 display and want to adapt it to a Chinese motor controller so as I can have the display communicating to the display and vice versa. The KT-LCD3 displays connection is 5 pins. Pin1 is Red+48-volt ( positive voltage directly from battery to display), pin 2 is control to motor controller, Pin 3 is Black-Ground., Pin 4 Tx Data, Pin5 is Rx data. The motor controller has 3 single wires coming from the controller. 1st wire is a Yellow with a green stripe and a label that says in Instrument panel. 2nd wire is Blue with a Green stripe and is labeled Hall Motor. 3rd wire is Brown labeled Phase Motor. My question is Can an adaptor be built to adapt the display to the motor controller so there can be communication between them?

I am sorry but at this point I don't have pictures of the motor controller.

KT-LCD will only work natively with KT controllers, so you will have to make a translator device, like an Arduino based "superharness" to connect it to a different type of controller. Gladly the KT protocol is well known (S-LCD to S12S controller communication protocol hacked), and I had an experience of pairing KT-LCD8 with a Sabvoton.

With respect to your single wire controller, not sure, it sounds very atypical for ebikes. I looked up online, and found some pics of what you are describing. People speculate it may be a LIN protocol. I have no idea. Maybe someone else can chime in. But yes if you know both protocols you can make an Arduino or other microcontroller adapter to have both work together.
