摘要
设计一套家用通风系统,以STM32F103ZET6为主控芯片,通风电机采用直流电机,利用按键控制STM32的通用定时器TIMx输出可调PWM（Pulse Width Modulation）信号,通过电机驱动芯片L298N改变直流电机的转速,实现通风系统转速调节。系统软硬件设计简洁合理,效率高,在智能通风领域具备一定的应用价值。
A set of household ventilation system is designed, with STM32 F103 ZET6 as the main control chip, the ventilation motoruses DC motor, the key control STM32＇s universal timer TIMx output adjustable PWM（Pulse Width Modulation） signal is used tochange the speed of the DC motor through the motor drive chip L298 N to realize the adjustment of the speed of the ventilation sys-tem. The software and hardware design of the system is simple and reasonable, and its efficiency is high. It has certain applicationvalue in the field of intelligent ventilation.
