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
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!
![](http://img.e-com-net.com/image/info10/7c827f37d54544cd9a9a64f048d8abf4.png)
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
打开此文件,找到第70行左右
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
首先要有一张BMP图片
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。
