0;}注：可以利用getchar()函数让程序调试运行结束后等待编程者按下键盘才返回编辑界面，用法：在主函数结尾，return 0；之前加上getchar()；即可getchar 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。

12864中文字库液晶测试实验
实验七、12864中文字库液晶测试实验
（一）、实验目的：
熟悉12864中文字库液晶模块的管教定义以及接口连接控制方式，学会用C语言编写12864液晶模块的驱动程序，并在此基础上通过单片机的控制将文本数据或图形数据显示在该液晶屏上。
（二）、实验接线和步骤：
串行控制方式测试实验
1、将液晶电源VLCD跳线用短路块接好。
这是所有液晶模块的电源。
2、将U13（上面的8位拨码开关）的“6”、“7”、“8”三位拨到“ON”位置。
这三
位是控制和串行数据接口。
3、将液晶12864插入20引脚的“C”（串-拼音的首字母），注意引脚对应。
4、下载测试程序。
并行控制方式测试实验
1、将液晶电源VLCD跳线用短路块接好。
这是所有液晶模块的电源。
2、将U13（上面的8位拨码开关）的“1、5、6、7”四位拨到“ON”位置。
并行方
式数据口使用的是P0口。
将U14的所有拨码都断开，防止8位4联数码管影响
P0口电压，进而影响该液晶的数据传输。
3、将液晶12864插入20引脚的“B”（并-拼音的首字母），注意液晶板引脚插针和
实验板插座对应位置（1对应1，20对应20）。
4、下载测试程序。
说明：因程序例程篇幅过长，不方便以书面形式列出，为方便使用者，例程的原代码及工程文件所有文档均已附在电子文档“12864中文字库液晶测试实验”文件夹中。
使用者可在例程程序的基础上改变某些参数以观察不同的实验效果。
