Classes
struct	struct_ConfigSG90
	the data set that configures the SG90 motor More...

class	SG90
	the class that manages the SG90 step motor More...

Macros
#define	STEP_ns 2000
	arbitrary value, gives resolution step_ns/(pos_max_us - pos_min_us) = 100ppm.

#define	PHASE_CORRECT false
	if PHASE_CORRECt = true, channel B is used as a synch pulse in the begining of channel A pulse else channel B is used as a synch pulse in the middle of channel A pulse.

#define	PERIOD_us 20000
	20ms according to SG90 data sheet

#define	T_MIN_us 500
	according to data sheet, should be 1000us but is 500us actually

#define	T_MAX_us 2500
	according to data sheet, should be 2000us but is 2500us actually.
