/* 程序详细功能介绍： *当按下按键P3.3 ，AT89S51单片机产生“叮咚”声从P3.2端口输出 *程序设计方法 * 1． 我们用单片机实定时/计数器T0来产生700HZ和500HZ的频率，根据定时/计数器T0，我们取定时250us， * 因此，700HZ的频率要经过3次250us的定时，而500HZ的频率要经过4次250us的定时。 * 2． 在设计过程，只有当按下SP1之后，才启动T0开始工作，当T0工作完毕，回到最初状态。 * 3． “叮”和“咚”声音各占用0.5秒，因此定时/计数器T0要完成0.5秒的定时，对于以250us为基准定时2000次才可以。 */-/* Procedure detailed functional Introduction:* When pressing the button P3.3, AT89S51 Singlechip a
