为什么OLED能用Print函数：
继承了print

1.常用函数

这几个函数都在GFX库中
在这里插入图片描述

1.字体

oled.print

oled.setRotation(1);

oled.setTextSize(1);

oled.setCursor(35, 5);

void loop() {
  oled.setRotation(1);
  oled.setTextColor(WHITE);//开像素点发光

  oled.clearDisplay();//清屏
  
  //设置字体大小  
  oled.setTextSize(1); //设置字体大小  
  
  //设置显示位置
  oled.setCursor(35, 5);//设置显示位置
  
  oled.println("-TonyCode-");
  oled.display();  delay(5000);oled.clearDisplay();//开启显示----5秒----关闭显示

  oled.setRotation(2);
  oled.setTextSize(2);//设置字体大小  
  oled.setCursor(15, 30);//设置显示位置
  oled.println("OLED TEST");

3.显示汉字

3-1：用这个软件取模
https://www.jb51.net/softs/109793.html#downintro2

3-2：在文字输入框输入文字，按着Ctrl+enter 就输入进去了

3-3：在取模方式项选择C51格式生成代码
