Arduino控制12864字符液晶案例

1、业界约定俗成的简称。主要控制芯片一般为ST7920或与之兼容的IC。大家在网上搜索12864时，总会发现带不带字库，它们的分别：带字库版不需要用点阵生成器把汉字变成点阵后再输入，直接输入汉字内码即可显示出对应汉字，无字库版想要显示汉字，只能自己按照点阵方式驱动。硬件特性：提供 8 位，4 位并行接口及串行接口可选并行接口适配 M6800 时序 自动电源启动复位功能内部自建振荡源6416 位字符显示 RAM（DDRAM 最多 16 字符4 行，LCD 显示范围 162 行）2M 位中文字型 ROM（CGROM），总共提供 8192 个中文字型（1616 点阵）16K 位半宽字型 ROM(HCGR

22、(); delay(3000); NAME(); delay(3000);上面的效果图如何获得的呢？首先英文字母不需要麻烦，直接输出就可以；然后介绍下如何获取汉字内码，我们打开汉字内码获取工具（由ardyPro所写，很好用；本帖也有下载链接），然后输入想要显示的汉字，例如：“工作室”；点击转换，转换结果就会出现内码了，如下图，其中“0xB9, 0xA4,”就是“共”字的内码，将其复制到程序中就可以使用了汉字一个字占两个字符，相当于两个英文字母的大小，所以我们程序中LCDA.DisplayString(0,4,show1,AR_SIZE(show1);/第一行第五个字开始，显示文字工作室的语句是从第五个字开始显示，因为“YFROBOT”占用了7个字符，就相当于占用了4个汉字的位置！下面我来介绍下图片是如何获取的，你需要个图片取模工具（本帖最后有下载链接），打开它，然后找到你想要显示的图片，这里我就以上面程序中的图片为例了！图片如下：然后我们通过PS软件打开它；再在PS中新建一个128*64的空白图片：然后我们将我们的图片经过一些处理：将其尺寸改小，能拖到128*64的空
