Help with Mini Maestro USB Servo Controller

Hi everyone,

I recently purchased the Mini Maestro 24-Channel USB Servo Controller https://www.pololu.com/catalog/product/1356 to control a few Hitech HS-7940TH http://www.servocity.com/html/hs-7940th_servo.html.

However, I don’t know how to set up the code to control the servo. Does anyone have any sample code to offer? I am running ubuntu 10.04 and ROS-Cturtle. Also, if the controller board is connected to my computer through miniusb, can the servos be power by that as well? Or, do I need an external power source?

Thank you,

Hello,

Controlling the Maestro is as easy as sending the right bytes to the virtual serial port, so search Google for “linux serial port example”, and you will find a lot of tutorials that will help you get started. Please see Writing PC Software to Control the Maestro for more information and a link to our USB SDK, which provides an alternative, more advanced way of controlling the Maestro.

The servo power cannot come from USB, since USB can only provide 500mA, and servos might each take 1A or 2A.
