在Keil环境下，用1302实现的时钟，用6位数码管显示时间,显示格式00:00:-In the Keil environment, to achieve by 1302 the clock, with six digital display time, display format 00:00:00

以上程序使用PIC12C508单片机，内部4MHZ时钟，4脚输入50HZ脉冲信号，7，6，3脚（GP0，GP1，GP4端口）为输出口。其中渐变部分是让灯慢慢的变亮（或灭--It uses PIC2C508 SCM, 4MHZ clock, 4 port is for inputting 50HZ signal, 7/6/3 port for output.
