You need to make sure that you always start with RADIO_MODE_PTX mode, otherwise the original crazyradio.py won't work anymore. If you update both, c-code and crazyradio.py, you can do most changes. (Just keep in mind that if you do make a mistake, you might need a JTAG programmer to revive your craz...

You essentially look at a hex-string, not at a hex-number. Every "digit" in hex can be 0-F, which represents the numbers 0-16 in the decimal system. Therefore, every "hex digit" requires 4 bits to store. For your example this means: 0xe7e7e7e7e7: 0x is just the encoding to tell y...

You open cmd.exe, in the upcoming black terminal window you change directories to wherever you downloaded pyusb to (e.g. "cd /folder/where/setup.py/is"). Once you are there you can type the command mentioned above "python setup.py install".

It might be a security related issue or a radio-in-use-issue. Try the following: 1.) Make sure that you deal with both scenarios in the same way, i.e. don't double click on cfclient while you use a command prompt to run ramp.py. Specifically, try to use a command prompt for both cases. 2.) Try to us...

Unfortunately, the state-of-the-art is that this is impossible. The onboard controllers measure acceleration and angular velocity, hence getting the position requires to integrate twice. This is suspect to noise and just after a few seconds you get the drift as you described. Calibrating reduces the...

A few tips: 1. Try to keep the orientation of the flie => Start learning how to control the yaw first while the flie is basically still on the ground. 2. Make sure that you trim the flie properly: http://wiki.bitcraze.se/projects:crazyflie:userguide:tips_and_tricks 3. Make sure that the flie is on a...

It sounds like it can't find pyusb. How did you install it? Did you run ?

When do the motors spin then? This is actually a feature of the firmware which only happens during start-up. All motors are supposed to spin during power-up for about half a second. Also check the connection to the motors (where you soldered the cables to the PCB) to make sure that you don't have a ...

Can you try to connect to it using the bootloader, as described here: http://wiki.bitcraze.se/projects:crazyf ... bootloader ?

There are some additional dependencies (pyusb, pygame etc.), but if you are able to run the cfclient, you have most likely everything you need. For the beginning, you should try to run the samples directly without eclipse. Open a command prompt, navigate to the folder with the samples, and type &quo...
