c8051f020里面自带的温度传感器的使用程序，经调试通过。

这是原创的基于PIC单片机的红外数据传送的接口程序包-This is the original PIC microcontroller-based infrared data transmission interface package

这是24c02通用IC卡的驱动， 是我自己写的，并已经测试通过-24c02 this the definitive driver IC card, I wrote it myself, and has been tested through

该源代码为单片机的电风扇课程设计源代码，需要课程设计报告的，再找我。-The source code for the MCU fans curriculum design source code, the need for curriculum design report, I find.

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.
