51 单片机包含头文件 BIN51.H 直接写二进制
最近学习 51 单片机，写代码的时候感觉用二进制的形式更直观。就是每次都需要宏定义，太麻烦。干脆把所有的8位二进制数字全部用宏定义写出来，放进头文件，下次使用直接包含头文件就行。
软件环境：win10 专业版 + Keil C51
创建 BIN51.H 文件, 使用 GB2312 编码, 文件内容如下:
/*--------------------------------------------------------------------------
BIN51.H使用说明
把 BIN51.H 放入 Keil 的目录, 例: C:\Keil\C51\INC
随后,可以直接在原文件中直接写二进制数字,例如:#include <reg51.h>
#include <bin51.h>
void main(void){P0 = B_1110_0001;while(1);
}--------------------------------------------------------------------------*/#ifndef __BIN51_H__

以上就是 BIN51.H 头文件的全部内容.
找到 Keil 的安装目录,例如: D:\Program Files (x86)\Keil ,将 BIN51.H 复制到
D:\Program Files (x86)\Keil\C51\INC 目录中.
测试代码如下:
#include <reg51.h>
#include <bin51.h>
void main(void)
{
P1 = B_1111_0000;
while(1);
}
根据我的开发版上的接线，显示的效果应该是 LED18 ~ LED15 亮灯,其余灭.
如果在你的开发板子 LED 显示效果不一样，可以调整杜邦线的线序，或者把P1 = B_1111_0000; 改成 P1 = B_0000_1111; 再测试.
