Latest version of my quadcopter controller with an LPC1768 and MPU9250.

Dependencies:   mbed

Currently running on a custom PCB with 30.5 x 30.5mm mounts. There are also 2 PC apps that go with the software; one to set up the PID controller and one to balance the motors and props. If anyone is interested, send me a message and I'll upload them.
