PWM输出口自然就能输出频率为2000Hz、占空比为1/2duty的方波。b)I/O口定时翻转电平驱动蜂鸣器方式使用I/O口定时翻转电平驱动蜂鸣器方式的设置比较简单,只需要对波形分析一下。由于驱动的信号刚好为周期500μs,占空比为1/2duty的方波,只需要每250μs进行一次电平翻转,就可以得到驱动蜂鸣器的方波信号。在程序上,可以使用TIMER0来定时,将TIMER0的预分频设置为/1,选择TIMER0的始终为系统时钟(主振荡器时钟/4),在TIMER0的载入/计数寄存器的高4位和低4位分别写入00H和06H,就能将TIMER0的中断设置为250μs。当需要I/O口驱动的蜂鸣器鸣叫时,只需要在进入TIMER0中断的时候对该I/O口的电平进行翻转一次,直到蜂鸣器不需要鸣叫的时候,将I/O口的电平设置为低电平即可。不鸣叫时将I/O口的输出电平设置为低电平是为了防止漏电。 蜂鸣器的作用 蜂鸣器是一种一体化结构的电子讯响器,采用直流电压供电。杨浦区施耐德AD16系列蜂鸣器厂家

电路图箭头朝里:PNP单极管;箭头朝外:NPN的单极管小圆圈为插针。用一根杜邦线将插针与单片机引脚相连,单片机引脚输出低电平,单极管导通,e、c连通,形成回路,有源蜂鸣器发声;无源蜂鸣器需要(与蜂鸣器种类有关,实际使用时可测试)的音频信号,即产生一个不断的高低电平变化,高低电平变化频率为3、单片机I/O口驱动能力非常微弱,不可以通过单片机I/O口直接驱动蜂鸣器,必须通过外接驱动电路,使R39电阻,单极管和R19电阻构成电流的放大电路从而可以驱动蜂鸣器,而不是依靠单片机管脚驱动蜂鸣器4、占空比:高电平时间方波:高电平、低电平时间相同~:取反符号,将管脚输出电平状态取反含有上拉电阻,默认输出高电平。高低电平各延时一段时间。杨浦区施耐德AD16系列蜂鸣器厂家
