[项目] 用OLED屏显示图片（制作篇）

[复制链接]
今天给大家带来OLED屏显示图片的制作方法
需要图片的请看https://mc.dfrobot.com.cn/thread-299362-1-1.html
需要代码的请看https://mc.dfrobot.com.cn/thread-299357-1-1.html


那么话不多说，开始。

首先，先从网上找到需要的图片（注意，图片要简洁，背景最好是白色）

用OLED屏显示图片（制作篇）图1(自己画的）如果你是从网上找得彩色图片，比如这个
用OLED屏显示图片（制作篇）图2
或者这个
用OLED屏显示图片（制作篇）图3（这个不推荐用）
那么你就需要进行转换
先把背景扣掉
用OLED屏显示图片（制作篇）图4
再打开画图

点重新调整大小中像素一栏，调整像素（方照片为64x64，长照片为128x64，最多不超过128x64）
然后另存为BMP格式

选单色位图

稍微改一下图

完成，打开取模软件Img2Lcd。
打开你的图片，点保存。把C文件改成TXT文件
十六进制模如下

  82.   display.clearDisplay();//清屏

  83.  

  84.     display.drawBitmap(0,0 , str1, 128, 64, 1);

  86. 

  87. void loop() {

  88.   // put your main code here, to run repeatedly:

复制代码

注意，如果是128x64的图
最后一句为

display.drawBitmap(0,0 , str1, 128, 64, 1);
如果是64x64的图
最后一句为

display.drawBitmap(0,32, str1, 64, 64, 1);
