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

};
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},

/* (16 X 16 , 宋体 )*/
{0x80,0x00,0x00,0x01,0xFC,0x7F,0x44,0x04,0x44,0x04,0xFC,0x3F,0x44,0x04,0x44,0x04},

/* (16 X 16 , 宋体 )*/OLED显示屏显示结果
