提供一个小弟的程序,有点笨,请各位看后,不要见笑.-provide a younger procedures, a bit stupid, you see, not laughed at.

本设计主要由数字信号发生器和逻辑分析仪组成，其中数字信号发生器运用了89C51单片机系统，可以重复输出8路循环逻辑移位序列，逻辑分析仪用了89C55单片机系统，可以实现8路信号的采集和显示(时间域和空间域)，3级触发字可调，有多种触发功能，可显示时标线,使逻辑分析仪能从大量的数据流中获得有分析意义的数据。-primarily by the design of digital signal generator and logic analyzer, composed of digital signal generator used 89C51 systems, which can output eight repeat cycle shift logic sequence, logic analyzer with the 89C55 microcontroller system, can achieve a 8-way signal acquisition and display (time Victoria and space domain), three adjustable trigger word, a number of trigger functions, can show that the time scale, so the logic analyzer from the large amounts of data flow has been analyzing the meaning of the data.

HD7279的程序，从51上移植到avr上面的程序，传上来提供大家参考-HD7279 procedures, from 51 on avr transplanted to the above procedures, Chuan-up to provide U.S. reference

设计程序使一个LED发光管以0.6秒为周期闪烁，即发光管每0.3秒点亮或熄灭一次。 分析题目要求，主要涉及两方面的操作，即控制LED发光管的亮灭以及定时0.3秒。对于LED发光管，只用一个IO就可以控制了（例如使用IOA0）；而对于0.3秒定时，我们可以利用TimerA定时器轻易地实现。-The design process of a LED to LED blinking 0.6 seconds for the cycle, that is, every 0.3 seconds LED lit or extinguished once. Analysis of the subject requirements, mainly related to two aspects of the operation, that is, control LED LED light out as well as the timing of 0.3 seconds. The LED light-emitting tube, only one can control the IO (such as the use of IOA0) and for 0.3 seconds from time to time, we can use to easily achieve TimerA timer.
