这是一个在LCD128*64上显示图形的一个程序，一直以来都总是不知道怎么搞，现在终于都通了，想当初在网上总找，要不是程序不全，就是无法运行，或者是C51汇编语言，让人不爽，这样的痛苦不可以再让别人难受了。
在LCD上显示一幅图，是“我的电脑，我的文档”。
IC用PIC16F877A，晶振4MHZ，采用并行8线，LCD：TS12864-3，接法在程序中有定义，只要将此程序COPY到你的PICC里编译下载后，在目标板上即可以看到图画了！不知道可不可以加酷？#include "pic.h"#define RS RC0#define RW RC1#define E RC2#define PSB RC3#define RST

LCD12864液晶的使用之字库型液晶(二)
Read_L=ReadByte(); //读低8位
write_LCD_command(ROW+0x80); //送入垂直地址
write_LCD_command(xlabel+0x80);//再送入水平地址
if(xlabel_bit<8)
{
switch(color)
address++;//指针地址指向下个位置
}
}
}
还有一点要注意的就是显示图片和显示ASCII码、汉字的初始化函数不同，显示图片用的是扩展指令：
void init_BMP()
{
write_LCD_command(0x36);//CL=1--8位。扩充指令(RE=1)，绘图打开(G=1)
delay(100);//适当延时
下面这个显示温度曲线：
这两个的仿真图大家可以做一下！

{

}
else//显示的是下半屏
{
ROW=y-32;
xlabel+=8; //规定显示在下半屏
}
write_LCD_command(ROW+0x80); //送入垂直地址
write_LCD_command(xlabel+0x80);//再送入水平地址
ReadByte();//读取当前GDRAM数据前腰进行一次空读，接下来就可以读出数据了
break;
default:break;
}
write_LCD_data(Read_H);//将数据写入GDRAM

的用途是从从标准输入流读取一个字符，读回车符时退出getchar();永远只向缓存中输入一个字符，getchar();的用法很多；一种就是清空回车符这种情况一般发生在在循环中涉及到输入的情况还有一种是某些编译平台（IDE)在运行程序时并没有在程序运行后给人看结果的时间这时候在程序最后加上getchar()就能造成程序的暂停给程序员度结果的机会用getchar时，在键盘上按一个字符后，要按回车才能读取进去；用getch时，在键盘上按一个字符马上就被读取进去，不用按回车，因此可以作为“按任意键继续”的执行语句。
