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.

用51汇编语言设计的DTMF发生器程序 输出到PI的每次间隔是52个指令周期 主频：6M，6M/12=0.5M,每个指令周期：2uS 即每次输出到P1的时间间隔是122uS 指令周期数：52 + 9 = 61-51 assembly language using the design process DTMF generator output to the PI for each interval is 52 instruction cycle speeds : 6M, 6M/12 = for 0.5 per instruction cycle : 2uS that each output to the P1 time interval is 122uS instruction cycle : 52 9 = 61

MCS―51单片机系统扩展 简单的并行接口由数据寄存器和少量的控制电路组成，暂存传送的数据。以锁存器、缓冲器为主要芯片，稍加控制都可以作为简单的并行接口.-MCS-51 single-chip microcomputer system to expand a simple parallel interface from the data register and a small number of control circuit components, temporary storage of data transmission. To latches, buffers as the main chip, a little control can be used as a simple parallel interface.
