Abstract
A laundry washing machine includes a weight sensing system including a weight sensor positioned to sense at least a portion of a weight associated with a wash tub and configured to output an associated pulse width modulated (PWM) force signal having a duty cycle that varies with applied force on the weight sensor. A controller of the laundry washing machine includes a state change sensing logic circuit coupled to receive the PWM force signal from the weight sensor and execute an interrupt service routine triggered by each state transition to capture a timestamp associated with each state transition such that the duty cycle of the PWM force signal may be determined using the captured timestamps.
