Any interest in STM32 Pypilot motor controller

[seandepagnier]

The scale for P I an D are in degrees relative to full speed movement. Essentially it gets filtered down so that the motor is not running all the time at very low speeds because this generally uses more power and is usually also inefficient. It is possible to implement a PID loop directly in the motor controller in the future if this is what you refer to, but pypilot generally outputs speed commands. If it is running with rudder feedback the PID loop is implemented in python, although this probably is a little sloppier.

Another option would be to write motor controller drivers for pypilot that support various open source motor controllers.
