Re: Crazyflie development virtual machine

For the documentation the main part is still planed to stay on the wiki, and we have to improve it even further. But of course the VM will contains at least couple of README files that explain how to get started and the rest should be pre-configured so that it is easy to use. For Python we are curre...

Re: Upgrade in future

Hi Egor, 1) Yes it is possible to install larger battery and motors. If using brushed motors we currently have about 5W power and our power path should be good for about 15W (dixit http://forum.bitcraze.se/viewtopic.php?f=6&t=4&p=7&hilit=motors+power#p7 ). If you are interested in brushless motors T...

Re: Motors facing up or down??

We have been thinking about it. I am not sure the efficiency would be changed but the center of gravity would be higher which would make the copter more stable (some would say less fun ;)). We also though to test motors facing up and down. Not too sure what would happen: best case we get twice as mu...

Re: crazyflie-firmware

As said Macus we are using arm-none-eabi-gcc 4.7 maintained by ARM.

For the code size it becomes a bit better with -Os (Setting DEBUG=0 in config.mk, good to use if no jtag debug is planned):

Code: Select all

   text	   data	    bss	    dec	    hex	filename
  47700	    400	  16336	  64436	   fbb4	cflie.elf

Re: OS

There is no way to fit Linux in our processor as we have 128K of flash and about 20K of ram so small RTOS like FreeRTOS is the only way to go.

Re: Source Code Location?

This is actually mercurial repos. We are not planing on switching to Git as mercurial suits our needs. The mercurial work-flow is very similar to git. If you really cannot get used to mercurial it is still possible to work with git while pushing/pulling to mercurial: http://stackoverflow.com/questio...

Hi,
The source code is at https://bitbucket.org/bitcraze

It is still missing some pieces but everything should be uploaded during the weekend
