Can someone Plz test this code and just see if the Motors are working?

Why is your entire user control code not in the usercontrol loop?

#3

we can’t test your code because our robots aren’t identical to yours

#4

i believe they just want to make sure the motors spin, if im not mistaken

#5

ah I didn’t actually go and read the code lol. thought they wanted us to test their robot’s code with our robots. my bad

#6

no problem haha. often times its when they dont have access to motors or something

#7

I haven’t tested it, but I can give a few recommendations after skimming it:

  1. Put your user control stuff in the user control task for cleanliness.
  2. Move your motor declarations to robot-config.h to clean up this file.
  3. You have two embedded while(true) or while(1) loops. That’s wasted code muddying things up. The outer one will never repeat because you get stuck in the inner one.
  4. You’ve commented that you’re using an odd form of semi-arcade/semi-tank control, but you’ve coded it for tank control.
  5. You’re trying to spin Arm1 at 200% of its maximum speed. Won’t happen. I would either change the number or change the units.
  6. Get rid of those two “else if” parts in the Arm1 commands and just use a single “else” to stop the motor. It will clean things up.
