Bitcraze Forums

It's on the wiki and the bitbucket repo.

You need a soldering iron to assembly the Crazyflie (CF).
You need a way to control the CF using something like an Xbox or PlayStation controller.
If you want to do in-circuit debugging of your modified CF code you'll need a debugger/programmer.

Downloading new code through the crazyradio is one easy way. When using openOCD then you would use a programmer to do it through the JTAG port instead.

There's lots of good info on the wiki.
The bitcraze Virtual Machine has a pre-configured Dev environment to help get you started quickly.

Yes, you would need to modify CR firmware to read in a command and then have it transfer the command to the transceiver.

The CF isn't very aerodynamic, so I don't think echolocation would stop a lot of the human caused crashes. It's a cool project though especially for more automated flying.
Sudden changes in direction can cause the CF's flight to become unstable, which causes you to crash anyways.

An ARM dev kit from ST will have the least amount of porting effort. They may have discovery board with the same/similar MCU as the crazyfile.

I'm not sure what you mean by 'compatible dev kits' but the crazyflie is basically a dev kit (but without the built in debugger like a lot of them have now). I think the path of least resistance would be a STM32 Discovery kit. I haven't got around to trying it yet but the discovery boards have a deb...

The program on the crazyflie is written in C.
The PC program is written in python. There is also a c++ port of the library for the PC.

The crazyflie uses I2C so you can write software for any sensor that has I2C.

You need to swap the propellers. The ones marked 'A' should be on M2/M4.
