Multirotor Flight Controller for the Robotics Cape

Please don't use this and expect it to work the way you want it to!!!!! I wrote this purely for my own use. NOT FOR PUBLIC USE!!!! It comes with no warranty, no manual, and I won't answer questions about how it works. If it breaks something, you get to keep both pieces.

However, enough people have asked me for it so here it is.

Note: depends on libjson-c-dev & libjson-c3 sudo apt install libjson-c-dev libjson-c3
