PIC12C508单片机控制灯光源程序以上程序使用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）。-PIC12C508 MCU control over light source uses PIC12C508 microcontroller, the internal 4MHZ clock, four feet 50HZ input pulse signal, 7,6,3-pin (GP0, GP1, GP4 port) for output. Gradient part of which is to make lights slowly brighten (or eliminate).
