What do you miss on the controller side?
Do you know how to calculate that?
Ok, I got it.1N4001 wrote: ↑May 05, 2018 4:31 amNot derivative, the opposite. Ah (or better Wh) is the integral of current/power over time. Take power measurements at regular intervals, say 1s, then add up 1/3600 of it to the total.
e.g. exactly 100W for each measurement, over the course of 1 hour, will give you 100 Wh (Watt-hour).
Good point!!lqbweb wrote: ↑May 07, 2018 1:22 pmHave you seen the luna ebike kit with the 2 speeds Xiongda motor hub? That color LCD is using the same protocol or a variant of the Kunteng controller i think.
It would be awesome to have a full LCD display, instead of the LCD3. You could display a lot more information. Maybe the efforts should be spent there instead? What do you think?

It doesn't appear to be sold separately. I also doubt it'll be easy to reprogram. And if it is, it won't be easy to work with as it's graphics-based. But I am curious nonetheless, it could have potential.
What about a general-purpose LCD? It would improve flexibility and could be much smaller. A character-based LCD, like the one used on the CA3 could be an idea.
For example swap the odometer with a wattmeter at the push of a button. Or have it cycle on its own periodically. Or show the motor temperature, but only if it exceeds a certain treshold. As I said, flexibility.
Of course you'd also need some buttons to control the whole thing. There might be LCD cases with built-in buttons already.
I quick looking at datasheet seems it works just as the same way, the commands, signals, etc. Also the PCB seems to be the same!!!nieles wrote: ↑May 16, 2018 12:32 pmHi,
just opened up my display and noticed mine has a different display driver (SHT32E22) but it looks like its pin compatible for the connected pins as far as i could see..
hopefully its also firmware compatible so we dont need multiple firmwares.
is the test code up on the repository?
Thank you for the feedback.rote wrote: ↑May 16, 2018 8:32 pmHi casainho,
I don't get on the forum as much as I used to but know you've been working for a while on these KT projects. Good stuff. I am interested in this KT display project. Like others have mentioned, I think it would be cool if you could get one of the outputs to display real-time current (A) and/or accumulated current (Ah) (like the Cycle Analyst).
Sorry I'm not a developer so can't help you with coding. In any case, I wish you good luck!
LCD shows only limited information sent by the controller like wheel speed, battery current and voltage, etc.
