ESC speed control

Vedder esc

C SOURCE CODE SimonK in contrast is a compiled hex file. Uses http://chibios.org/dokuwiki/doku.php RToS. Use this code on the hardware from OsmcRobotics.

Github
L298N https://github.com/ovaltineo/SegwayClone/blob/master/Motors.ino code.
 * https://github.com/rene-dev/stmbl stmbl is an open source servo drive designed for Retrofitting CNC machines and Robots. It supports Industrial AC and DC servos with up to 320V and 1kW.
 * https://github.com/ovaltineo/SegwayClone Segway clone. Added support for Osmc robotics without MOB (Modular OSMC Brain). Supports http://www.instructables.com/id/Motor-Driver-BTS7960-43A/?ALLSTEPS BTS7960 motor driver.

 * https://github.com/bluerobotics/blueesc/ ,https://www.bluerobotics.com/store/electronics/besc-30-r1/ The BlueESC is a simple, open-source electronic speed controller for three-phase brushless motors. It is designed to run the SimonK firmware on an Atmega8 microcontroller. Derived from https://github.com/sim-/tgy,  https://code.google.com/p/wii-esc/

Motor control
https://github.com/ytai/ioio/wiki/Motor-control The Motor Control API, which was added to the IOIO library in version 5.00 makes it easy to control a large variety of such setups with very high accuracy and speed. What it does essentially is generate digital waveforms of various kinds, which correspond to different kinds of actuators.

ESC settings

 * TIM1 - 3-phase FET bridge PWM
 * TIM2 - ADC synchronization, works in lockstep with TIM1
 * TIM3 - RGB LED PWM
 * TIM4 - Hard real time callout interface for motor control logic (preempts the kernel)
 * TIM5 - RC PWM input capture
 * TIM6 - High precision timestamping for motor control logic (sub-microsecond resolution, never overflows)
 * TIM7 - General purpose timestamping

filter
Remove the low pass filter on the ESC, allowing higher P(proportional) control values, which stabilizes the quad in wind gusts.
