Brushless DC controller (ESC)
Fully functional sensorless ESC.
Uses BEMF detecton for rotor position sensing.
Software trays to maintain maximum speed on currently available power(pwm duty).
It works like ordinary DC motor. More load means, on same power, lower speed and higer current.
Motor speed (current) PWM , direction etc. is adjustable via serial port commands.
For example - press "k" button to add power, "j" button to reduce power and "t" button
to reverse rotor...
