51系列单片机无PWM输出功能，可以采用定时器配合软件的方法输出。对精度要求不高的场合，非常实用。电路图见图一，采用了高速光隔（6N137）输出，并将PWM的信号倒相。
-51 series microcontroller no PWM output function, can be used with the method of software timer output. On the occasion of the precision requirement is not high, very practical. See chart a circuit diagram, using high light every (6 N137) output, and the signal pour phase PWM.
