Abstract:
A method of determining a direction of rotation of a shaft is disclosed, as well as an integrated circuit chip that uses the disclosed method. The method includes receiving a first binary signal and a second binary signal from a transducer attached to the shaft, with the first and second binary signals being in quadrature. A present quadrant identification number, QID PRESENT , is determined as a two-digit binary number by left-shifting a value of the first signal and adding a value of the second signal. After a sampling interval has elapsed, the method sets a past quadrant identification number, QID PAST , to the value of said QID PRESENT , determines a new value of QID PRESENT  and calculates a value of a transition code using an equation that operates on QID PRESENT  and QID PAST . The method uses the transition code to determine a direction of rotation of the shaft.

Claim (Index 12):
An electronic device comprising:\n one or more inputs to receive first and second binary signals that are in quadrature with one another; a processor coupled to the one or more inputs; and a memory coupled to the processor to store instructions that, when executed by the processor, cause the processor to:\n determine a present quadrant identification number (QID PRESENT ) based on the first binary signal and the second binary signal; \n after a sampling interval has elapsed, set a past quadrant identification number (QID PAST ) to the value of QID PRESENT , determine a new value of QID PRESENT ; and, after the determination of the new value of QID PRESENT , determine a transition code as a function of QID PRESENT  and QID PAST ; and \n in response to a determination that the transition code is valid, use the transition code to determine a rotation direction, produce a direction of rotation signal indicative of the rotation direction, generate a motor control signal based upon the direction of rotation signal, and output the motor control signal.
