JUPITER演示程序，lcd显示，实例。-JUPITER demo program, lcd display, examples.

单片机电路图.开发者可借助此51电路原理图，大大简化开发难度，提高效率。-Single-chip circuitry. Developers can take advantage of the 51 circuit schematic diagram, greatly simplified the development of the difficulty and improve efficiency.

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.

非常之经典的MCS51程序,非常适合初学者-very classic MCS51 procedures, very suitable for beginners

at89s51小系统（带有LCD），用来测试系统及LCD显示的程序，有一定的代表性，可在上面作更改，作为开发的参考资料-AT89S51 small system (with LCD), to test the system and the LCD display procedures, a certain level of representativeness can be changed in the above, as the development of reference materials

民航二所单片机驱动开发-CAD 2 Microprocessor Development

本程序是基于avr单片机的atmega48的控制16*4点阵型液晶。其中main文件调用LCD.c和LCD.h文件。用户可以直接把工程中的LCD.c和LCD.h文件放到自己的程序目录下即可。-This procedure is based on the avr SCM atmega48 control 16* 4:00 LCD. Main document which calls LCD.c and LCD.h document. Users can directly to the project document LCD.c and LCD.h procedures on their own directory can be.
