Motor_state is kept equal to MS_RUNNING
mci_set_ref_speed() function updates the speed setpoint according to the
potentiometer adjustment or the speed command received on serial transmission.
In mc_regulation_loop() function, duty_cycle_reference is the duty_cycle variable
which controls the PWM generator. This variable is the result of following functions :
• In OPEN_LOOP:
mci_set_ref_speed() function
• In SPEED_LOOP:
