bit.h

这里有很多我自己做的凌阳单片机源程序

/**************************************************************************************/
//位操作,另外,可以对字节操作,每一个单元(单位为16位的字)可以分为高八位和低八位操作;
//使用方法:下面的硬件寄存器都定义为了UNport结构体型的指针变量,使用时只要:
//端口名->bit.bit0就可以操作端口的第0位;
//端口名->byte.bytel就可以操作端口的低八位;
//端口名->port就可以操作整个端口;
//实际上,操作整个端口时可以用另外一个头文件"hardware.h",直接对*端口名操作就可以了;
