Is it possible to make some app for power levels?
Power level 1 - 4000W
Power level 2 - 6500W
Power level 3 - 9000W.
You can use the Profiles in mobile Vesc-tool app.
I thought about something like 3 positions-switch to choose power level but maybe your idea is better and easier to implement. Thnak you :)
Profiles are good if there is an easy way to switch them on the fly/go like with a button or a three position switch. This is a default feature present on every cheap Chinese BLDC or sinewave controller out there.
The easiest implementation is a handlebar push button that cycles the profiles but it provides no visual or tactile clue what the current selection is. A better implementation is two wires for three different states/profiles but obviously requires two inputs. Another way is to use a divider circuit in a three way switch to send different voltage levels (0,1,3v for example). Probably the best and easiest way way to do it on a VESC.
A simple app can check the state of an ADC pin and select the wanted profile.
