| Abstract: | In this paper, mainly introduces a thought of simulating value output through interface change-over circuit. The single-chip timer is applied to generate interruption, so as to make I/O interface output multi-path PWM signals. In this paper also introduces data configuration of single- chip timer buffer and provides an example program of interrupt service. |
