Define Documentation

#define _NEG_QD

(

in

)

{in.q=-in.q;in.d=-in.d;}

negate variable

Definition at line 153 of file QDOperations.h.

#define ASSIGN_QD	(	in,
		out		)	{out.q=in.q;out.d=in.d;}

assign in variable to out variable

Definition at line 159 of file QDOperations.h.

#define INV_QD	(	in,
		out		)	{out.q=_IQdiv(_IQ(1),in.q);out.d=_IQdiv(_IQ(1),in.d);}

Calculate the inverse of qd variable

Definition at line 143 of file QDOperations.h.

#define MAKE_QD	(	real,
		imag,
		out		)	out.d=real; out.q=imag

make qd variable from real and imag components

Definition at line 224 of file QDOperations.h.

#define MULT_REAL	(	dq,
		sc,
		out		)	{out.q=_IQmpy(dq.q,sc);out.d=_IQmpy(dq.d,sc);}

Multiplication of qd variable and sc real value

Definition at line 148 of file QDOperations.h.

#define NEG_QD	(	in,
		out		)	{out.q=-in.q;out.d=-in.d;}

Definition at line 154 of file QDOperations.h.

#define SIGN

(

in

)

(1+((in & (long)0x80000000)>>30))

obtain sign of _iq variable. It returns 1 if positive and -1 if negative

Examples:

TIMotorLIBExampleSw/main.c.

Definition at line 164 of file QDOperations.h.

#define SQRT_QD	(	in,
		out		)

Value:

{\
                                _iq mag = _IQsqrt(MAG_QD(in));\
                                _iq phase = _PHASE_QD(in)/2;\
                                REAL_QD(out)=_IQmpy(mag,_IQcos(phase));\
                                IMAG_QD(out)=_IQmpy(mag,_IQsin(phase));\
                                                                                }
