以点阵方式驱动显示汉字，实际上把每个汉字作为一个图形显示。

如是嫌一个个显示麻烦，可以把要显示的汉字画在一个图片中，一个语句就可显示出来。
参阅链接http://www.geek-workshop.com/thread-5529-1-1.html

Arduino IDE V1.01
专用版本的库Adafruit Adafruit-gfx

以张老师的SSD1306 I2C 12864显示器为例。

为了显示汉字，用字模提取 V2.0输出 图形字模。

1.输入汉字 “极客工坊”  s1.jpg


2 按回车结束输入 s2.jpg



3.选择C51格式，生成字模代码 s03.jpg


4．保存成文件
在基本操作中选择，保存成点阵数据

5.将数据拷入Arduino 程序文件中，如下
为防止变形，原始宽度是30，所以程序中图片的宽度也是30

Arduino 代码如下：
  1. /*********************************************************************
  2. *
  3. * // # Update the Adafruit SSD1306 library to make it work
  4. * // # Description:
  5. * // #                 show a simple animation
  6. *
  7. * // # Connection:
  8. * // #        SCL  -> A5(Uno)/D3(Leonardo)
  9. * // #        SDA  -> A4(Uno)/D2(Leonardo)
  10. * // #        RST  -> D4
  11. * // #        DC  -> GND
  12. * // #        3.3  -> 3.3v
  13. * // #        g  -> GND
  14. * // #
  15. *
  16. * This is an example for  OLED based on SSD1306 drivers
  17. *
  18. *
  19. * This example is for a 128x64 size display using I2C to communicate
  20. * 3 pins are required to interface (2 I2C and one reset)
  21. *
  22. * Adafruit invests time and resources providing this open source code,
  23. * please support Adafruit and open-source hardware by purchasing
  24. * products from Adafruit!
  25. *
  26. * All text above, and the splash screen must be included in any redistribution

本程序显示得不够精简，让人再笑了。如果用数组来表示，就会精简多了。
本人学识不足，目前只能这种写法了。

求解，这个程序显示汉字是一直在刷新的，怎么让汉字静止不刷新啊？
