How can I make PC-client using USB dongle?

[theMinss]

Hello,

I want to make windows PC-client program using visual studio 2008 c++.

I thought the usb dongle is port control device, because I have made other widows program.

But windows OS recognize the usb dongle as usb device, I can not control the usb dongle.

How can I make PC-client using USB dongle?

plz, give me key words or any suggestion..

Hi,

We use libusb to access the dongle from Python the the official client. You have many option depending of which library you want to use.
- LibUSB can be used from VisualStudio: http://wiki.bitcraze.se/projects:crazyradio:protocol
- Microsoft provides a similar library called winUSB: http://msdn.microsoft.com/en-us/library ... 85%29.aspx

Both library will give you access to low level USB operation that you can use to communicate with the dongle. The Crzyradio USB protocol is described in our wiki: http://wiki.bitcraze.se/projects:crazyradio:protocol. You can look at the python driver for reference: https://github.com/bitcraze/crazyflie-c ... zyradio.py

Depending of what library you chose to use you will need the correct driver for the dongle. The tool we use to install libusb driver can also install winusb driver: http://wiki.bitcraze.se/projects:crazyr ... dows_zadig

There is at least one Crazyflie C++ client on github that has a driver using libusb: https://github.com/Saqoosha/ofxCrazyfli ... yradio.cpp
