PWM输出口直接驱动蜂鸣器方式由于PWM只控制固定频率的蜂鸣器,所以可以在程序的系统初始化时就对PWM的输出波形进行设置。首先根据SH69P43的PWM输出的周期宽度是10位数据来选择PWM时钟。系统使用4MHz的晶振作为主振荡器,一个tosc的时间就是μs,若是将PWM的时钟设置为tosc的话,则蜂鸣器要求的波形周期500μs的计数值为500μs/μs=(2000)10=(7D0)16,7D0H为11位的数据,而SH69P43的PWM输出周期宽度只是10位数据,所以选择PWM的时钟为tosc是不能实现蜂鸣器所要的驱动波形的。这里我们将PWM的时钟设置为4tosc,这样一个PWM的时钟周期就是1μs了,由此可以算出500μs对应的计数值为500μs/1μs=(500)10=(1F4)16,即分别在周期寄存器的高2位、中4位和低4位三个寄存器中填入1、F和4,就完成了对输出周期的设置。再来设置占空比寄存器,在PWM输出中占空比的实现是通过设定一个周期内电平的宽度来实现的。当输出模式选择为普通模式时,占空比寄存器是用来设置高电平的宽度。250μs的宽度计数值为250μs/1μs=(250)10=(0FA)16。只需要在占空比寄存器的高2位、中4位和低4位中分别填入0、F和A就可以完成对占空比的设置了,设置占空比为1/2duty。以后只需要打开PWM输出。
