概述
你是否想拥有一个实惠而且高画质的OLED显示屏？你是否淘遍了所有网店也没有找到心仪的OLED显示器？
DFRobot为你献上精心挑选的2.7英寸128*64分辨率的显示器。这款产品拥有众多优点，绝对会让你爱不释手

2.7英寸超大屏幕，轻松显示图像和文字。
白色显示和黑色背景，简洁大气，突显画质。
超大显示广角。不论从哪个角度，你都能把上面的文字看的清清楚楚。
屏幕周围加黑色金属边框，提升质感和保护。
高强度磨砂表面。耐摔，无反光，非产适合安装到其他成品上面
最重要的是它无缝兼容Arduino，用起来就是那么简单。<bt>

由于该LED屏无背光光源，因此能得到纯黑的背景，与白色显示成鲜明对比。并且屏幕厚度比普通12864 LED屏薄一半，减轻重量，提升质感。该屏幕用SPI协议驱动，反应速度快。再加上附送的 "u8glib"代码库，让你快速应用这一优质产品。

技术规格
电压：5V/3.3V
最大电源消耗：110mA@5V
接口类型：SPI
12864分辨率
2.7英寸大小
尺寸：8558*6.5mm

字符显示
1.接线
与上面接线相同

2.字符显示演示代码
该显示屏需要用到库函数，库及其相关资料

#include "U8glib.h"
U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9); // SPI Com: SCK =DB0 = 13, MOSI =DB1 = 11, CS = 10, A0 = DC= 9
void draw(void) {
u8g.setFont(u8g_font_unifont); //修改字体请参照附件中fontsize - u8glib字体库
u8g.drawStr( 0, 22, "Hello World!");
}

void setup(void) {

}

void loop(void) {
// picture loop
u8g.firstPage();
do {
draw();
} while( u8g.nextPage() );
}

图片显示
1.图片转换
（1）打开图形转换软件，设置模式为图形模式。

1156.png
（2）设置参数为C5I

1168.png
（3）打开要转换的图像，图像格式为位图（bmp）

（3）然后点击生成字模即可，最后把生成的字模放入一个字符数组里面。

2.接线
与上面的接线方式相同

3.显示图片代码演示
该显示屏需用用到库文件，库及其相关资料

汉字显示
1.汉字转换
（1）打开PCtoLCD2002软件，选择模式为字符模式。

1156.png
（2）在文本框中输入字符“人”，设置参数为C5I，点击生成字模，最后把生成的字模放入一个字符数组里面。

1157.png
2.接线图
同上

3.演示显示屏显示汉字“人”代码
显示汉字同样需要用到库函数，#库及其相关资料下载

#include "U8glib.h"//库函数
U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9); // SPI Com: SCK = 13, MOSI = 11, CS = 10, A0 = 9 芯片类型及其对应的接线方式
const uint8_t rook_bitmap[] PROGMEM = {
0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,
0x01,0x00,0x01,0x00,0x02,0x80,0x02,0x80,
0x04,0x40,0x04,0x40,0x08,0x20,0x08,0x20,
0x10,0x10,0x20,0x08,0x40,0x04,0x80,0x02,/"人",0/
};
void draw(void) {
// graphic commands to redraw the complete screen should be placed here
u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap);//第0行0列开始显示文字，生成的汉字“人”大小为16*16，所以后面的两个参数为（16/8,16）.

}

void setup(void) {
}

void loop(void) {
// picture loop
u8g.firstPage();
do {
draw();
} while( u8g.nextPage() );
// rebuild the picture after some delay
delay(1000);
}

4.多个汉字显示代码注意事项 该取模软件，在生成字模时每个汉字会单独生成一个字模对应的数据，在显示多个汉字时，需要单独显示每个汉，即多次调用u8g.drawBitmapP( );这个函数。

void draw(void) {
// graphic commands to redraw the complete screen should be placed here
u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap1);//0行0列显示“机”
u8g.drawBitmapP( 16, 0, 2, 16, rook_bitmap2);//0行16列显示“器”
u8g.drawBitmapP( 32, 0, 2, 16, rook_bitmap3);//0行32列显示“人”
}

void loop(void) {
// picture loop
u8g.firstPage();
do {
draw();
} while( u8g.nextPage() );

// rebuild the picture after some delay
delay(1000);
}
部分代码解释
u8g.drawStr( m, n, str);//m代表的是第m列，n代表的是第n行，str是要显示的字符串
u8g.drawBitmapP( m, n, x, y, str);//m代表的是第m列，n代表的是第n行，x代表的是生成字模点阵时的列数除以8，y代表的是点阵行数，str是要显示的字符串

例如显示汉字“人”u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap);//在生成字模时大小为16*16，那么x=16/2;y就是第二个16.
