We have bought the mentioned Servo Controller and have connected it to a power source and one servo. Using the Maestro Control Center we can set the Position of the servo and the servo moves. But we do not know, how to send commands via USB from a Ubuntu System using C++.
How can we move the servo without using the Maestro Control Center?
The serial port method is the easiest, but if you want to use native USB, we provide C# example code for using the USB interface that uses the libusb library to interface to the device - you could use that code basically as documentation when writing your own code to use libusb in C++, or find a way to access our C# classes from C++.
