89c51详细介绍-89c51 in detail introduced

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.

液晶方面的一些资料文件 希望有所帮助关于51语言-LCD some hope that help information paper on the 51 language

实现了有凌阳的外部中断进行技数，同时有2赫兹的内部定时器，以实现对外部频率的采集 -Sunplus has achieved the technology to a number of external interrupt, while Hertz has 2 internal timer in order to realize the acquisition of external frequency

这是一个电池放电器，能够很好的工作。谢谢！-This is a battery of electrical appliances up to a good job. Thank you!
