摘要：提出了一种基于单片机与AD9852的信号源的实现，重点介绍了单片机与AD9852硬件接口电路、AD9852串行工作流程以及宽带滤波器设计的关键技术。 关键词：AD9852；信号发生器；频率合成

本源程序使用C51控制的PLL(SANYO LC72131)收音,可以通过HT1621驱动LCD显示,有完整的按键控制程序模块,能通过KEY进行各种功能操作,整个程序采用模块化设计,移植方便,可以初学者参考使用.(之前的那个也是我上载的,怎么就没开通?)-C51 use the source control PLL (SANYO LC72131) radio, Driving through HT1621 LCD Display, a complete module button control procedures, KEY through various functional operation, the whole process has a modular design and facilitate transplantation, beginners can use and reference. (which is also before I posted, how never opened)

鉴于MCS-51系统只提供“二级中断嵌套”，提出扩展51系统中断优先级的纯软件方法。其利用51系统内建的中断允许寄存器IE和中断优先级寄存器IP，通过屏蔽字机制来实现；以C51的形式，给出这种扩展方法的函数库实现，为该方法的使用赋予友好、简洁的用户接口。-Given MCS-51 systems only provide "two interrupt nesting," expanded 51 priority system interruption of pure software. The use of 51 built-in system allows interruption Register IE and priority interrupt register IP, through word shielding mechanisms to achieve; C51 in the form of this expansion is the way to achieve functions, methods for the use of empowerment friendly, simple user interface.

利用89S52为核心实现的IDE-USB转接器 现在已经实现了主要功能：可以读取文件和复制文件。不支持格式化硬盘功能。 不过速度比较慢，我从本地硬盘复制文件到移动硬盘里去，速度只有50KBytes/S， 因为单片机速度不快，内存又少，USB1.1的速度也不快。另外，代码写得不够好 压缩包内有线路图-89S52 realize use as the core of the IDE-USB adapter now realize the main function: You can read the files and copy files. Reformat your hard disk does not support the function. More slowly, however, I copy files from the local hard disk to a mobile hard drive into a speed only 50KBytes/S, because of slow single-chip, memory less, USB1.1 speed is not fast. In addition, the code written is not good enough compression packages have circuit diagram
