| Abstract: | In the development of intelligent products, many micro controllers do not offer PWM output pin. But PWM output is required in some particular cases. To resolve this issue, the timer of single chip microprocessor was utilized to generate PWM wave output through softwave design, which simplified the product hardware design, improved durability, decreased the cost and enhanced competitive ability enhanced. |
