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

    No idea, but if you open the Github repository and navigate to display.c, then scroll down to about line 200, you'll see what the controller expects to receive from the LCD. There you can witness which parameters actually get assigned. P1 - P5, C1 - C5, C12 - C14. I haven't looked into where...

    I too had this issue, and I suppose this is something that has affected many users since the newer versions of sdcc. Try to downgrade to an older version of sdcc.

    Yes, the middle leg (drain) on the blue FETs is connected to the positive rail on the PCB. It's fine, I'm grateful for your cooperation and help I recieved. I'll try to get my hands on a scope and/or poke around on the PCB in hope to find any clues to what could be wrong.

    By following these notes bmsbattery_s06s_controller_hardware/S06S.Txt at master · KingQueenWong/bmsbattery_s06s_controller_hardware And this pinout I could read 2.5v on all of the PWM high pins(26, 27 ,28), and 3.5v on all the PWM low pins(20,21,22). With the throttle disconnected.

    No magic smoke on my watch;). But there is a slight problem, the MOSFETs marked with blue(K150E09NE) are the only ones that receive any gate voltage, which also is strange. You said that the low side should have 5v, and the high should be at about half the battery voltage. Now the only reads I...

    Sadly no, I don't have access to an oscilloscope. Do you know any other way of debugging? The PCB looks fine, there's at least no visible damage. May it be an incompatibility of IC's? I've searched through this thread and I couldn't find anyone with a 3PEAK TP104 op amp. The sensor should be...

    It seems that "TIM_CR1_CEN" doesn't exist. I suppose you meant "TIM1_CR1_CEN"?

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

    You're right! SDCC doesn't seem to find uint_PWN_Enable. And therefore nothing was flashed onto the controller. Also, The throttle momentary could be seen in BlueOsec, it should be visible on my previous screenshots.

    Sorry! The Java tool loaded up the wrong config and I didn't seem to notice. Here is the output with the right config. Still 0.

    Doesn't even flinch. (Keep in mind, the controller is only connected to the battery, hc-05 and throttle at the time of diagnostics).

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

    Unfortunately it doesn't seem to be that easy, the wheel spins freely while on full throttle, should I do something while in diagnostics? Like spin the wheel, push the throttle or pas? Here's a clean output when the controller isn't connected to anything.

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

    So I have flashed the controller with new parameters. I've set the speed limit to 100 km/h on every occasion (offroad ,no pas, limit) I've also checked my wheel circumference and set it to 2230 in the software. I also counted my magnets and divided them by 2 as in the wiki. Which results in...

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

    Thank you for your reply stancecoke. I didn't know that the second number in BlueOsec also was a control state. But there's a slight problem, (1 | 17) is shown when the wheel (that the DD motor is mounted on) isn't spinning, and (1 : 34) while it's spinning. No matter if I pedal or not. My...

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

    I'm living in a country where e-bikes with throttle isn't legal, and so I don't use any. Instead I have a pas sensor installed. But no, I've tried to turn the sensor individually and with no luck. The motor remains still but BlueOsec does seem to register pas activity. Edit: I got my hands on a...

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

    Hi everyone! I've just flashed the firmware onto my controller and I'm having this strange problem where, I got everything hooked up (PAS, Hall sensors, Phase) but the when I turn the pedals and my PAS sensor starts register movement. The motor just doesn't do anything and spins with the pedals...

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

    But is it possible to change the speed or other parameters through the LCD? or is it only possible through a flash of a modified firmware? Sorry for the stupid questions. I'm new to this and the wiki doesn't give a clear answer.

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

    Hi! I've been thinking about flashing my KT36/48SVPR with this firmware. I have read all the docs on both the website and GitHub page of this project. But I still have some of my questions unanswered. 1. The Github page states that the P and C parameters on the LCD3 have been mapped...
