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.

本程序是一个将CanOpen协议的通讯转换为TTL串口通讯(9600,e,7,1),CANOPEN的站号是9-This procedure is a communications protocol will CANOpen convert TTL serial communication (9600, e, 7,1), CANOPEN station is No. 9

本程序是用于通用同步和异步串行接收器和转发器（ＵＳＡＲＴ），使用中断方式异步接收和发送数据通信源的程序文件。-this procedure is common for serial synchronous and asynchronous receiver and transponder (USARTs), the use of asynchronous interrupt receive and transmit data communication source program files.

主要功能是实现16*16LED阵列的汉子显示，程序简单易懂，适合刚刚接触单片机和c语言的学者-Main function is to achieve 16* 16LED array guy show, the program simple and easy to understand, for just contact with scholars of microcontroller and c language
