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：
/*********************************************************************
*
* // # Update the Adafruit SSD1306 library to make it work
* // # Description:
* // # show a simple animation
*
* // # Connection:
* // #    SCL-> A5(Uno)/D3(Leonardo)
* // #    SDA-> A4(Uno)/D2(Leonardo)
* // #    RST-> D4
* // #    DC-> GND
* // #    3.3-> 3.3v
* // #    g-> GND
* // #
*
* This is an example forOLED based on SSD1306 drivers
*
*
* This example is for a 128x64 size display using I2C to communicate
* 3 pins are required to interface (2 I2C and one reset)
*
* Adafruit invests time and resources providing this open source code,
* please support Adafruit and open-source hardware by purchasing
* products from Adafruit!
*
* All text above, and the splash screen must be included in any redistribution

delay(2000);
display.clearDisplay(); // clears the screen and buffer
//清屏

}

int WIDTH=30; //汉字点陈宽度是30
int HEIGHT=29; //汉字点陈高度是29
void aa()//显示汉字
{
//由于每个汉字点陈宽度是30，所以它们间距是32比较合适
display.clearDisplay();
display.drawBitmap(0, 0,bmp1, WIDTH,HEIGHT, 1);
display.display();
//显示汉字“极”
display.drawBitmap(32, 0,bmp2, WIDTH,HEIGHT, 1);
display.display();
//显示汉字“客”
display.drawBitmap(64, 0,bmp3, WIDTH,HEIGHT, 1);
display.display();
//显示汉字“工”

display.drawBitmap(96, 0,bmp4, WIDTH,HEIGHT, 1);
display.display();
//显示汉字“坊"
delay(1500);
}

void loop() {
aa();//显示汉字

}

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。

也遇到这个问题，求解答，

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？
