This is a mcu programmar to control NFR2401

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.

这是一个很简单的有51单片机就可以实现的PID 控制算法，虽然不是很准确，但是作为一个学习案例，还是很有意义的-PID ,C51 IMPLEMENT

此程序为AD9850（DDS）直接数字频率合成器C语言源码。用125M的有源晶振，频率无失真输出可达到40M。该程序包括FYD12864LCD显示程序加4X4矩阵键盘扫描，可步进1M，1K，和任意频率输入。及相位设置。-This procedure for the AD9850 (DDS) Direct Digital Frequency Synthesizer C language source code. With 125M active crystal, the frequency output can be achieved without distortion 40M. The process includes the display program FYD12864LCD plus 4X4 matrix keyboard scanning, may be stepping 1M, 1K, and arbitrary frequency input. And phase settings.

收录了许多51单片机的汇编程序，完全可以用于移植开发。同时，也对51学习者进行学习提供了很好的学习教材。
