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

    at the end I could not get my motor to go without jerking. can someone help me interpret the screenshots? if I turn on dc_static_zero and spin the wheel, I don't see any graph. some kind of wave is visible only when you first turn it on. Is this normal, or is this some kind of malfunction...

    I have the same controller kt36/48svprd-fff1 and spent days getting it to work. I would be glad if I had the same reason :) but for me it spins and rides, but it works in jerks, so everything is shaking, like on a moped)

    can anyone help me with my setup? my motor spins at angle setting from 193 to 215. and I don't like how it works at all. if interpolation is disabled, then it only makes noise and jerks; maybe this is evidence that phases are connected incorrectly? everyone here has an angle a little different...

    I am using Debian based Linux with sdcc 4.3 - it works. I just got binutils from platformio project. your problem was probably in option bytes - a timer is configured there, and in linux there is no beautiful gui for this)))
