Two functions select the regulation loop. Open loop and speed loop.
tion loop implemented in the software.The two functions are mc_set_speed_loop() and
mc_set_open_loop().
In open loop mode, the reference speed is used as duty cycle for the PWM.
Used to stop the motor.
Sets the reference speed.
Returns the reference speed.
Sets the motor direction ‘CW’ (clock wise).
Sets the motor direction ‘CCW’ (counter clock wise).
Returns the direction of rotation of the motor.
Saves the measured speed in the measured_speed variable.
Gets the measured speed.
