是用AT89C2051主控音量控制PT2258,数码管显示, 红外线遥控,2.1/5.1音源选择)包括全套原理图,源程序,HEX文件-AT89C2051 is PT2258 master volume control, digital control, infra-red remote control, 2.1/5.1 sources choice), including a full set of schematics, source, the HEX file

数码管段码速查,在单片机开发时，很容易的控制数码管-digital control of the Code Check, in MCU development, it is easy to control the digital control

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.
