  • I use a combination of this servo controller plus a couple xbees as a controller for my airplane and my quadcopter.

    Here is the program I wrote using Visual C# 2010 Express and the SlimDX SDK to pull data from a joystick, modify it, and send it out over a serial port.


    Here is a link to a thread I started about auto-resetting the controller after a fatal error. It also has a diagram of my airplane setup using only one battery to power everything.


  • Your .NET example link is broken. Here is a link to a simple servo control program I made using Visual C# 2010 Express.


  • I had the same problem where the device would not respond to anything I sent it.
    The data sheet says VLogic (VIO) voltage can be up to VDD. Wrong! You can’t just tie them together.
    To solve this I made a small voltage divider circuit with two 10k resistors in series between 3.3V and ground. I connected VIO to the junction between the two resistors (3.3V/2 = 1.65V) and now the gyro works every time.

No public wish lists :(
