今天对软件做了调整使能显示全屏图像，如下图示：
11月19日晚于天津四项目部宿舍



原始图片



转换黑白后：


液晶显示器显示：





源程序：
  1. #include<reg51.h>
  2. #define uint unsigned int;
  3. #define uchar unsigned char;
  4. sbit rs=P1^0;//并行模式下为指令数据选择信H/L=指令/数据
  5. sbit rw=P1^1;//并行的读写信号H/L=读/写
  6. sbit e=P1^2; //并行下的使能信号
  7. sbit reset=P1^5;

  9.    uchar x,y;
  10.    uchar datetabal;
  11. uchar d1,d2;//数据缓冲
  12. uchar k=0,h=0;
  13. unsigned int i,j;
