Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

my code change will set the target power for walk assist to ±500w and limit the speed to 20km/h (to make it legal in Europe for speed pedelecs) :thumb: but just wondered if you have any plans to add walk assist to the 'Torque_from_X4' branch? You could have made the few changes yourself, but here y...

Re: Ebike assist level control

others be interested in an open source, perhaps programmable assist level button, maybe coupled with a display?

If someone can confirm that it works properly, I can push it to the master branch.
After a little bugfix, a german user confirmed that the walk assist works now. I've pushed the Walk_Assist branch to the master!

But, as I said, when I hold the "DOWN" button, the meter assist function logo flashes, but the function doesn't work.
Yes, but this is not a matter of the LCD8H, it doesn't work with any display, as the walk assist function is not implemented yet.

Of course Throttle min and Throttle max must be fitted to your sensor. Number of PAS magnets (Pulses per crank revolution) ...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I'd like to increase the max speed, but it doesn't work. I think the 1000W XOFO is a direct drive, this will never reach the max erps limit. I think in your case the speed is limited by the battery voltage. You have to use a Battery with higher voltage to get more speed. Another option would be fie...
