初学单片机的一个实例运用，以at89c2051为例，用c语言编写的时钟程序。程序采用了两级中断，具有时钟及秒表功能。-beginners MCU use an example to at89c2051 example, the language used c clock procedures. Adoption of the two suspended, with the clock and stopwatch functions.

程序描述：这个范例说明如何使用8051，以及汇编语言的程序连结， 当我们按下向上数的按钮之后，程序就会把0到9的共 阳7段显示器字型码存入AT93C46；如果我们按下向下 数的按钮之后，程序就会把9到0的共阳7段显示器字 型码存入AT93C46。 程序每一次重新开始执行时(Power on 或是Reset)，8051 会先从AT93C46当中读出最前面的10个位组，然后 就反复地将这10个位组的数据经由PORT 1送到1个 共阳七段显示器。*/-Procedure Description: This example shows how to use the 8051, as well as links to assembly language programs, when we pressed up a few of the button, the program will bring a total of 0-9 yang seven segment display font yards into AT93C46 if we press Next down the number button, the program will bring a total of 9-0 Yang seven segment display font code into AT93C46. Process to begin again each time when the (Power on or Reset), 8051 will start with AT93C46 were read out in front, 10-bit groups, and then repeated these 10-bit groups of data via the PORT 1 sent to a A total of seven-segment display Yang.* /
