外部计数+显示程序 功能： 单片机外部输入脉冲信号，定时器参与计数 计数值由数码管显示出来。...

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.

使用protel99软件编辑的原理电路图，希望对各位有助于电路图的学习和开发-The use of the principle of circuit protel99 software editor, in the hope you will help the study and development of circuit
