实验目的：加深对定时/计数器、中断、IO端口的理解，掌握定时/计数器、中断的应用编程技术及中断程序的调试方法。

实验内容：利用C8051F310单片机设计一个LED灯控制器

主要功能和技术指标要求：

1. LED灯外接于P0.0端。

2. LED灯分别按2Hz，1Hz和0.5Hz三种不同频率闪动，各持续10s。

3. 在LED灯开始和停止闪烁时蜂鸣器分别鸣响1次。

4. 利用单片机内部定时器定时，要求采用中断方式。

提高要求：

使用按键（KINT）控制LED灯闪烁模式的切换。

-Experimental purposes: to deepen the timer/counter, interrupt, understanding of the IO port, the master timer/counter, interrupt the application programming techniques and interrupt program debugging. Experiment: C8051F310 microcontroller design a LED light controller functions and technical requirements: 1. The LED lights external P0.0 end. 2. LED lights press 2Hz flashing 1Hz and 0.5Hz three different frequencies, each continuing 10s. Start and stop flashing LED lights buzzer ringing once. 4 MCU internal timer, the interrupt. Improve requirements: Use the buttons (KINT) control LED lights flashing mode switch.
