Motor synchronization
See original GitHub issueThere’s discussion that has been happening in https://github.com/ev3dev/ev3dev/issues/454 and https://github.com/ev3dev/ev3dev/issues/853 around synchronization of motors, mainly for wheeled robots. While kernel support for “proper” synchronization is not going to be arriving for a while, I think it’s reasonable to implement this as best as possible in this library and adapt to the kernel model later.
I’m thinking that a MotorPair class which operates on given motor objects and/or port names would be reasonable as a Python implementation. It would be nice to provide functions for steering, potentially similar to the EV3-G functions.
Thoughts?

+1 for this. In openroberta I first set all attributes and then start the motors like this: https://github.com/OpenRoberta/robertalab-ev3dev/blob/develop/roberta/ev3.py#L374 which is a pita.
@ddemidov maybe you are thinking of TankWebHandler in https://github.com/rhempel/ev3dev-lang-python/blob/develop/ev3dev/webserver.py , specifically around line 500 where it is starting two motors but with different speeds in order to turn the tank? This was the tank that uses a web interface with a little “joystick” dot that you move around inside a larger circle to control the speed/direction of the tank.
