Hello everyone. I am here asking a question about using the encoder values for our lift. We are trying to code a macro for towering with the press of a button, and I was wondering how to set the lift to stop at a certain encoder value so all you had to do was drop the cube into the tower(if that makes sense).
This is an idea that I had on how to do this:
start the lift at the original point
print out the encoder value of the lift motor
find the encoder value when the lift is at the top
If(button pressed and liftStartValue< endpointValue
keep going
else if(button pressed and liftStartValue>= endpointValue
Stop
Not sure if above code is correct though.
Help with this would be greatly appreciated. Thanks,
V5 is awesome and you can simply use the encoder ‘ticks’ for positioning
‘assuming’ your lift has a home (starting) position reset the encoder so this position is always ‘0’:
Lift.resetRotation();
there are three ‘spin’ methods:
Lift.spin() //- just turns the motor
LiftSpinTo() //- turn a specific position from home (absolute positioning’
Lift.spinFor() //- turns a specific about based on current position (relative positioning)
so on your button.isPressing() you can Lift.spinTo(#tower_ticks)
As far as figuring out how many ‘ticks’ you can try different values or get fancy and echo the encoder position to the screen…
when ever you’re using a spinTo/For you have to keep in mind the command is either blocking (true) or not (false) . Blocking means it will wait until it reaches the completion before letting the next command execute. This can really bite you if you’re not careful/mindful!
