This project contains the source code for the Crazyflie 1.0/2.0 firmware.
Install a toolchain
brew tap PX4/homebrew-px4 brew install gcc-arm-none-eabi
Tested on Ubuntu 14.04 64b:
sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded sudo apt-get update sudo apt-get install libnewlib-arm-none-eabi
sudo pacman -S community/arm-none-eabi-gcc community/arm-none-eabi-gdb community/arm-none-eabi-newlib
The GCC ARM Embedded toolchain for Windows is available at launchpad.net. Download the zip archive rather than the executable installer. There are a few different systems for running UNIX-style shells and build systems on Windows; the instructions below are for Cygwin.
Install Cygwin with setup-x86_64.exe. Use the standard
C:\cygwin64 installation directory and install at least the
Download the latest
gcc-arm-none-eabi-*-win32.zip archive from launchpad.net. Create the directory
C:\cygwin64\opt\gcc-arm-none-eabi and extract the contents of the zip file to it.
Launch a Cygwin terminal and run the following to append to your ~/.bashrc file:
echo '[[ $PATH == */opt/gcc-arm-none-eabi/bin* ]] || export PATH=/opt/gcc-arm-none-eabi/bin:$PATH' >>~/.bashrc source ~/.bashrc

This repository uses git submodules. Clone with the --recursive flag
git clone --recursive https://github.com/bitcraze/crazyflie-firmware.git
If you already have cloned the repo, use
git submodule init git submodule update
or with the toolbelt
tb make PLATFORM=CF1
This is the dafault build so just running "make" is enough or:
or with the toolbelt
To create custom build options create a file called config.mk in the root folder (same as Makefile) and fill it with options. E.g.
PLATFORM=CF1 DEBUG=1 CLOAD=0

Frameworks for unit testing are pulled in as git submodules.
The testing framework uses ruby and rake to generate and run code.
To minimize the need for installations and configuration, use the docker builder image (bitcraze/builder) that contains all tools needed. All scripts in the tools/build directory are intended to be run in the image. The toolbelt makes it easy to run the tool scripts.
