[嵌入式]7针oled显示中文及图片arduino。ug8lib

文章目录

前言：

7针oled（spi协议）的引脚说明：

关于中文的显示

关于图片显示：

取模软件

前言：

关于回家没带esp8266usb数据线，所以使用arduino和7针oled连接的小白。网上大多数的都是4针oled关于esp8266的显示教程，本人只有7针oled的。所以查了很多的资料，走了很多的弯路。

7针oled（spi协议）的引脚说明：

GND电源地GND
VCC电源正VCC
D0时钟管脚10
D1数据管脚9
RES复位管脚RES
DC数据和命令控制管脚11
CS片选管脚12

关于中文的显示


#include "U8glib.h"


U8GLIB_SSD1306_128X64 u8g(10, 9, 12, 11);  // SW SPI Com: SCL = 10, SDA = 9, CS = 12, DC = 11,RES=RESET

首先调用U8glib库程序，同时定义数据串口。

void loop(void) {

  u8g.firstPage();  
  do {
    draw();
  } while( u8g.nextPage() );

}

对主函数进行定义：分别调用显示开始和显示结束的函数u8g.firstPage()，u8g.nextPage()，这之间调用自己定义的draw()。

??

从取模软件进行获取字符串

void draw(void) {

 u8g.drawXBMP( 0, 0,16, 16, str[0]);
 u8g.drawXBMP( 16, 0,16, 16, str[1]);
 u8g.drawXBMP( 32, 0,16, 16, str[2]);
 u8g.drawXBMP( 48, 0,16, 16, str[3]);
}

u8g.drawXBMP

取模软件

我用的是??pctolcd2002 完美版：

这个软件画图的时候，每画一格就闪一下，非常的刺激眼睛。希望有大佬安利一下好用的取模软件
