1. lcd1602与lcd122323的区别???
LCD 1602 是字符电阵LCD 可以显示16个 英日字符（当然看字库，非标字库可以显示其他字符）。 12232是图形点阵LCD 一般不带字符库（用ST7920 IC 的带中文字符库） 两者写入显示图形的方式不一样。具体可见规格书中的指令表部分。
2. 初学单片机用12232还是1602？使用上有何区别？
1602比较多人用，但是，丑啊，都不想说它了。 买12232吧，对着规格书，折腾几下，东西就出来了。
3. 12864和LCD1602的区别是什么？各自的优势是哪些？
12864 顾名思义像素是128*64，能显示8*4个汉字，因型号不同，有的带汉字库，有的不带，能显示图像效果，功能比1602强大，1602只能显示字母、数字和符号能显示16*2个字符，但寄存器不止32个，具体也忘了，有一些显示效果，如字符一个个显示、字符从左到右或从右到左显示等等，显示效果简单，价格低，大约6块钱，而12864最少40块钱一块，在编程使用方面，两者难度差不多，原理差不多，都是写指令、写地址、写数据等等。全部手打，给分啊~
4. PROteus单片机仿真软件中通用型1602、12232、12864液晶的代码分别是什么呢？
要注意，你说的通用型其实并不通用，LCD模块中使用不同的控制器，其控制方法都不同！所有的LCD模块都在Optoelectronics大类下。 1602是LM016L； 12232有好几种： AGM1232G DISPLAY 122x32 Graphical LCD with SED1520 controllers EW12A03GLY DISPLAY 122x32 Graphical LCD with SED1520 controllers HDM32GS12-B DISPLAY 122x32 Graphical LCD with SED1520 controllers, LED Backlight HDM32GS12Y-3 DISPLAY 122x32 Graphical LCD with SED1520 controllers, Selectable Interface, VAC LED Backlight 12864也有好几种： AMPIRE128X64 DISPLAY 128x64 Graphical LCD with KS0108 controllers HDG12864F-1 DISPLAY 128x64 Graphical LCD with SED1565 controller, Serial data input HDG12864F-3 DISPLAY 128x64 Graphical LCD with SED1565 controller, Parallel data input HDG12864L-4 DISPLAY 128x64 Graphical LCD with SED1565 controller, Parallel data input, LED Backlight HDG12864L-6 DISPLAY 128x64 Graphical LCD with SED1565 controller, Selectable Interface, LED Backlight LGM12641BS1R DISPLAY 128x64 Graphical LCD with KS0108 controllers LM3228 DISPLAY 128x64 Graphical LCD LM4228 DISPLAY 128x64 Graphical LCD LM4265 DISPLAY 128x128 Graphical LCD PG128128A DISPLAY 128x128 Graphical LCD Display PG12864F DISPLAY 128x64 Graphical LCD Display TG126410GFSB DISPLAY 128x66 Graphical LCD with SED1565 controllers, Bottom View
5. LCD1602与LCD12864有什么区别
分辨率不同，LCD1602是每字5*8点阵，字符区域16*2个；LCD12864是128*64分辨率的点阵。 驱动芯片也不同，因此控制字、时序略有不同
6. 12864与12232液晶有什么区别。
液晶模组的图形点阵不同。
7. smc1602和lcd1602液晶显示有什么区别
汇编语言编程与使用什么外设没有关系，当然可以用汇编语言编程了，而且可以做到效率最高。
8. 新人求教：LCD12864和LCD1602的区别 本人想用12864做显示但不知道它和1602在编程上的区别，有什么需要注意
1602是指的16字符2行的那种吧。如果是，其点阵是这样的结构。其IC带有字库。想显示字符，只需要输入对应字的地址。
而12864的点阵是连续的。一般不带有字库。想写一个圆点，都要自己想好要写那些位置。屏上每个点都对应字IC内部RAM中一个BIT. 黑白的程序已经很久没有用了。不知道240*320彩屏的对LZ有帮助没有。区别是彩屏一个像素点需要16BIT数据（或者18，或者24）.
