Hello, folks,
built my three-year-old daughter a little bicycle.
but I have a little problem with the throttle response and the acceleration.
I built an electronic e-bike throttle and connected it to the ADC1 input. I set Min Voltage (0,85V) and Max Voltage (2,55V). Center Voltage is set to 1.7V.
My problem is that despite the setting at about 25% the engine already accelerates at full throttle. if I open the throttle slowly and then keep it at 15%, the engine still accelerates further.
i see this on the duty display and also on the realtime data.
i have tried it but i can't figure out what i'm doing wrong. hope someone can help me, she si struggeling ab bit when full throttel hits so directly!! ;))
thank you in advance!!

I just found it. I use Vesc-tool and I haven't selected in ADC App -> General tab -> Duty Cycle. I just selected it in the Mapping tab.
now work like a charm
You should use current control. And a second throttle for braking! If the cable brakes, the bike can go to full speed! Use a pulldown resistor next to the pins.

@frank I think you mean pull-down ;)
(the default connection of the ADC is to ground, i.e. 0)
