单片机的动手实践篇--51单片机玩转12864

作者:时间:2017-01-10来源:网络收藏

  液晶的驱动和1602的类似,只不过是多了几个扩展的功能,不如画图功能:

本文引用地址:http://www.amcfsurvey.com/article/201701/342707.htm

  这里讲一下:不要简单的认为是y轴64,x为128,那是点阵的分布,不是读写的分布,如正图表示,y轴的32行,从0到31,x轴的16 从0到15,0到7为上半个屏幕,8到15在下半个屏幕,所以绘图的时候,有两个部分要进行书写

  在上载入任意一幅图:

  示例代码:

  #include

  #define uint unsigned int

  #define uchar unsigned char

  sbit lcdrs = P2^4;//数据还是指令的选择端口

  sbit lcdwr = P2^5;//读写操作端口

  sbit lcden = P2^6;//使能端延时端口

  sbit PSB = P2^1;//串行数据还是并行数据的选择段

  //图片的编码,这幅图片的编码是一个哆啦a梦

  unsigned char code pic1[] = { /* 0X10,0X01,0X00,0X80,0X00,0X40, */

  0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,

  main()

  {

  init_12864();//初始化液晶

  setpic();//初始化液晶图片显示

  lcd_putpic(pic1);//载入一幅图片

  delay1ms(5);

  while(1);

  }

  以后载入图片只需要将图片用取模的软件,注意图片的大小必须是128x64的尺寸,否则会出现乱码,这是个比较容易犯的错误,希望大家注意
