oled制作动画效果图

oled

一 制作oled下载库文件

https://u16460183.ctfile.com/fs/16460183-296052483
文件夹说明：

Adafruit_SSD1306-master —— OLED库

Adafruit-GFX-Library-master —— 图形库

LS_DrawForOLED —— 主程序


image.png

在arduino文件中加载两种库文件，上传之后如果报错的话需要进行修改文件内容，找到arduino libraries文件进行修改代码
出现错误！


错误信息

error("Height incorrect, please fix Adafruit_SSD1306.h!");

错误信息意思是指：

高度不正确，请修正Adafruit_SSD1306.h！

（1）进入Arduino安装文件夹的libraries文件夹的Adfruit_SSD1306-master 找到Adafruit_SSD1306.h


image.png

打开此文件，找到第70行左右


image.png

默认是定义 SSD1306_128_32 ，由于我们使用的是128*64的OLED，所以，把原来的#define SSD1306_128_32,前面加上//

把#define SSD_128_64 前面的//去掉

二 。 制作一张BMP图片

image.png

首先要有一张BMP图片


image.png

自己用windows自带的画版画了一张大气的 晴朗大山浮云图，保存为BMP格式。

通过软件找到图片的点阵像素，经过像素出现像素码。

代码编写

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET 4

Adafruit_SSD1306 display(OLED_RESET);
