LPS node firmware

This project contains the source code for the Local positioning System node firmware.

Dependencies

You'll need to use either the Crazyflie VM, install some ARM toolchain or the Bitcraze docker builder image. If you install a toolchain, the arm embedded gcc toolchain is recomended.

Frameworks for unit testing are pulled in as git submodules. To get them when cloning

git clone --recursive https://github.com/bitcraze/lps-node-firmware.git

or if you already have a cloned repo and want the submodules

git submodule init        
git submodule update        

OS X

brew tap PX4/homebrew-px4
brew install gcc-arm-none-eabi

Debian/Ubuntu linux

Download, extract and put in your path the compiler from https://launchpad.net/gcc-arm-embedded. For example:

mkdir -p ~/opt/
cd ~/opt
wget https://launchpad.net/gcc-arm-embedded/5.0/5-2016-q3-update/+download/gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
tar xvf gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
mv gcc-arm-none-eabi-5_4-2016q3 gcc-arm-none-eabi
rm gcc-arm-none-eabi-5_4-2016q3-20160926-linux.tar.bz2
echo "export PATH=\$PATH:\$HOME/opt/gcc-arm-none-eabi/bin" >> ~/.bashrc

On 64Bit Linux you also need to install some 32Bit libs:

sudo apt-get install libncurses5:i386

If all works you will be able to execute arm-none-eabi-gcc:

$ arm-none-eabi-gcc --version
