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。
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。

Oled与Uno的接线图
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。 (2)设置参数为C5I (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。 (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。
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。

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.
