视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.

/* 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
