摘要： A system and method for determining a microstep rotor offset of a stepper motor is provided. The system includes a microcontroller configured to control voltage applied to a first coil and a second coil provided to operate the stepper motor; a back electro-magnetic force (BEMF) detection circuit configured to detect BEMF generated from the stepper motor. The stepper motor drives a pointer with a pointer stop, and the system is configured to: 1) home the stepper motor to the pointer stop, and 2) perform an iterative operation to determine a specific microstep associated with the microstep rotor offset.

摘要： A method of measuring the period of a vehicle speed signal is disclosed that includes the steps of accumulating predetermined time interval increments between first and second rising edges of the signal, calculating a remainder time interval upon detection of the second edge of the signal and adding the remainder to the accumulated increments value to obtain the period, and calculating an average period from a plurality of consecutive period measurements. If the accumulated value exceeds a predetermined maximum value before the second edge occurs, the maximum value is used in calculating the average.

摘要： An aspect of the present disclosure provides a system and method for determining a touch input for selecting a feature on a touch display. The system includes a sensing circuit disposed adjacent to and separate from the touch display by a predetermined distance. The sensing circuit having an emitter sensor and a receiver sensor, where the emitter sensor projects infrared (IR) light to the touch display and the receiver sensor detects a change of intensity of the IR light in response to a user presses on the touch display such that a threshold force is met when the predetermined distance between the touch display and the sensing circuit narrows by a predetermined amount.
