You're seeing the correct thing. The Flie reports the serial connection back to the computer. The name "Crazyflie" is a human term, whereas the device the computer sees is a serial connection to the microcontroller.

A better choice is to tune the PID values as necessary. The pitch and yaw are controlled in the firmware, and the latency between the client and flie would lead to your trim values always being just a little too late for a given correction.

X-mode makes your "Forward" direction the red light on the CF1. I believe it turns the edge of the board between M1 and M4 into "Forward" on the CF2. It's more controllable in that you have two motors' thrust increasing or decreasing for a given rotation instead of one in the pit...

Damn, too bad I'm in the US. The props may or may not work. I don't see why they shouldn't. If they're a different size you'll get different flight characteristics. Smaller, you'll need more thrust to do anything. Different profile and they may respond to control adjustments more or less sluggishly....

You're going to need to spend a bit of time learning the crazyflie firmware and client code first. You'll need knowledge of C and Python, and a few days of reading through, charting, and working with the control structure of the control code. The most relevant bits would be the PID controller, the S...

It looks like your only problem is that the readme.md files aren't merging properly. Just skip the error to finish the rebase, and manually merge the readme files if you changed it. It should work just fine. This error specifically means that the same line of your file has been changed by two differ...

I had the same problem on my M4 motor. See: http://forum.bitcraze.se/viewtopic.php?f=5&t=1283 Contact Seeedstudio about replacement mosfets or having them repair it. You can also purchase new mosfets. The part number from the wiki is PMV31XN, and an alternate option is PMV30UN. Both of these are...

You'll need to write the interface yourself. The protocol information is available on the wiki at http://wiki.bitcraze.se/doc:crazyradio:usb:index. The relevent USB driver code is written in python. You can find it on the crazyradio-firmware github at https://github.com/bitcraze/crazyradio-firmware/...

Yes, the flie gyro has drift. Every gyro is going to drift like this, actually. The algorithm for correction with a magnetometer is the same one currently implemented, actually. The current one is a 6DoF (Gyro and Accelerometer) version of the Madgwick and Mahoney filters for sensor fusion. There ar...

I noticed the current firmware build on the wiki is 2014.01. I've just built the master branch, and figured I'd post the current 2015.01 binary for everyone to use. PLEASE NOTE: This has been tested to connect and work on the Crazyflie 1.0 ONLY. This is the vanilla build from the Bitcraze master. If...
