How to control multiple servos at the same time?

Question

Python

There are two servos connected to the Raspberry pi.
I manage them through the library https://github.com/adafruit/Adafruit_Python_PCA9685
But I need them to move at the same time. How to do it?
Tried to implement through streams - did not work.

Answer 1

Do you have a motor driver? Usually they put a 2 or 4 channel driver, where by changing the voltages at its logical inputs, you can control several engines at once.

Answer 2

First, what drives are connected to the Raspberry, exactly how?
Secondly, what does "at the same time" mean? When is the time delta between the start of movement of the drives equal to zero?

Answer 3

Most likely, my proposal will be sent to the forest, but what you need and a lot of incredibly polar digital supporters is implemented in my patent-pending service processing

Why did you decide to write? I'm looking for a business angel ;)
So far, I'm looking for the first orders for the promotion of a startup in favorable conditions for investing capital.
