目标
1、汉字取模软件的使用 2、OLED显示屏显示汉字
实验材料
Arduino UNO开发板 12864液晶显示屏 配套USB数据线 配套杜邦线若干 Arduino IDE软件
内容
OLED显示屏显示汉字“长度”
接线图
接线方式
Arduino UNO <------> 12864液晶显示屏 5V <------> VCC GND <------> GND 10 <------> SCL 9 <------> SDA 13 <------> RES 11 <------> DC 12 <------> CS
需要使用到汉字取模软件 取模软件界面
选项设置
点击设置后,在字模选项中取模方式选择逐行式,自定义格式选择C51格式
输入汉字“长度”,选择字体和大小,点击生成字模,将生成的字模拷贝到程序中
程序实现代码
- #include "stdio.h"
- #include "stdlib.h"
- #include "U8glib.h" //OLED显示屏库文件
- U8GLIB_SSD1306_128X64 u8g(10, 9, 12, 11); //OLED显示屏引脚设置SCL=10,SDA=9,CS=12,DC=11
- static const unsigned char changdu[2][32] PROGMEM={
- {0x10,0x00,0x10,0x08,0x10,0x04,0x10,0x02,0x10,0x01,0x90,0x00,0x10,0x00,0xFF,0x7F,

- /* (16 X 16 , 宋体 )*/
- };
- void draw(void) {
- u8g.drawXBMP( 0, 0,16, 16, changdu[0]);
- u8g.drawXBMP( 16, 0,16, 16, changdu[1]);
- }
- void setup(void) {
- }
- void loop(void) {
- u8g.firstPage();
- do {
- draw();
- } while( u8g.nextPage() );
- }

备注:生成的字模拷贝到程序后,把“长”和“度”的中间“{}”删掉,原先“长度”生成字模: {0x10,0x00,0x10,0x08,0x10,0x04,0x10,0x02,0x10,0x01,0x90,0x00,0x10,0x00,0xFF,0x7F}, {0x50,0x00,0x90,0x00,0x10,0x01,0x10,0x02,0x90,0x04,0x50,0x18,0x30,0x60,0x10,0x00},/*"长",0*/ /* (16 X 16 , 宋体 )*/ {0x80,0x00,0x00,0x01,0xFC,0x7F,0x44,0x04,0x44,0x04,0xFC,0x3F,0x44,0x04,0x44,0x04}, {0xC4,0x07,0x04,0x00,0xF4,0x0F,0x24,0x08,0x42,0x04,0x82,0x03,0x61,0x0C,0x1C,0x70},/*"度",1*/ /* (16 X 16 , 宋体 )*/
