https://www.youtube.com/watch?v=QSIksPKndEs However the Interrupt service routine for the encoder could be much more simple: use this on one Hall sensor's pin: attachInterrupt(digitalPinToInterrupt(pin), ISR, mode), and the 'mode' should be 'RISING'And to get the direction in the 'interrupt service routine', you only have to check whether the other Hall sensor's pin is HIGH or LOW at that moment.

Hackflight is a simple, platform-independent, header-only C++ toolkit for building multirotor flight controllers. It is geared toward people like me who want to tinker with flight-control firmware, and use it to teach students about ideas like inertial measurement and PID tuning.

State machine using millis() for crude multi tasking 
nick rehm dRehmFlight VTOL is a new flight controller and stabilization package intended to be used for small to medium sized hobby or research projects. dRehmFlight is the code, and the physical flight controller is a Teensy 4.0 microcontroller with an MPU6050 IMU. This lightweight flight controller can be used for anything from basic multirotors, to advanced VTOL configurations, to simple fixed wing platforms. See inverted pendulum control with drone. 
Arduino code and Five_axis_mill#grblgru low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328. The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses
