OLED/LCD WEB在线图片取模工具，用arduino玩
1、第一，给大家介绍使用方法：
1.准备一张图片，图片分辨率应小于你的显示设备2.在网页中上传图片3.复制生成的代码到你的程序中
2、第二，给大家看看u8g2测试代码：
可以看一下效果。
/*
使用u8g2显示数据
图形显示器：OpenJumper 12864 OLED

void setup(void) {
u8g2.begin();
}
void loop(void) {
u8g2.clearBuffer(); // 清空显示设备内部缓冲区
u8g2.drawXBMP( 0 , 0 , 55 , 64 , col ); //50,50为图片尺寸，根据你的图片尺寸修改
u8g2.sendBuffer(); // 显示缓冲区内容
delay(1000);
}
3、最后，给大家看一下效果图啦。
希望大家多多学习，可能涉及的知识比较多。
