主要功能，采用C8051F330，功能强大，已大

程序详细功能介绍： * 利用AT89S51单片机的P0端口的P0.0－P0.7连接到一个共阳数码管的a－h的笔段上， * 数码管的公共端通过三极管8550选通。在数码管上循环显示0－9数字，显示时间的间隔可通过修改延时程序。 -Procedures detailed functional Introduction:* use AT89S51 MCU port P0 is connected to P0.0-P0.7 Yang a total digital control of the a-h T segment,* digital tube through the public side-gated transistor 8550. In the digital control on the circulation figures 0-9 show, indicating the time interval may be delayed by modifying the procedures.

因需要，单片机的键盘扫描和数码管显示共用一口，用定时器实现，原创-Due to the needs of single-chip microcomputer keyboard scanning and sharing a digital tube display with a timer to achieve the original

DTMF双向收／发集成电路MT8880专门为双音频信号的收、发而设计，它既能产生发送双音频信号，又能对双音频信号进行接收译码，还能判断各种信号音(拨号音、回铃音、忙音)。以上就是它的应用电路和程序-Two-way DTMF collection/fat MT8880 IC specifically for the dual audio signals received, the design, it could have sent dual audio signal, while the dual audio signal decoding receiver, but also to judge the sound signal (dial tone , ring back tone, busy tone). Above is its application circuit and procedures

该程序是用单片机C51语言编写的关于步进电机控制的程序，里面包含了详细的说明，对于初学者有很好的帮助！
