实现文字的显示
这代码上实现在指定的坐标显示指定的中英文字
先看看效果图
相关开源代码：
//显示中英文字符程序
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);
#define LOGO16_GLCD_HEIGHT 16 //定义显示高度
#define LOGO16_GLCD_WIDTH 16 //定义显示宽度
//中文：凌 （这就是存储点阵变量，str_1可以修改成自己喜欢的名称，用函数display.drawBitmap（）调用就可以了）

display.drawBitmap（）调用就可以了）

}可能有人好奇这些乱七八糟的怎么来的？↓
这其实就用到 字模提取V2.2 的软件了 ，打开软件，具体操作如下：
把点阵生成的数组，套入程序的相关变量，调用相关的函数就可以实现显示中文。
其实取模软件，就是把中文字转换成点阵，实现在没有中文字库程序中显示中文。
我想有字库的也是这样的点阵库，如有理解错误请指出。
