发明名称 Methods and Systems of Controlling an Electronic Device's I/O Terminals Using Pulse-Width Modulation
摘要 An electronic system includes a signal processor, a control signal generator, and an I/O interface. The signal processor has a first output signal and the first output signal is characterized by at least a first property and a second property. The control signal generator is configured to produce first and second control signals in accordance with the first and second properties of the first output signal, respectively. The I/O interface is configured to couple at least the first and second control signals to an output device. In some embodiments, the first output signal is a pulse width modulated signal having a software-specified pulse width and a software-specified repeat frequency. In some embodiments, the first property of the first output signal is the signal's duty cycle and the second property is the signal's frequency.
