九号之眼

介绍

起因是我看网上的九号之眼挺好看,然后想弄一个结果太贵了,查阅了教程发现没有于是打算自己做一个

开源

源码来自:https://giltesa.com/en/2021/01/05/photographic-album-using-esp32-and-gc9a01-round-screen

效果展示

输入图片说明

没找到原素材所以随便弄了个眼睛

所需材料

esp32模块 淘宝链接:https://m.tb.cn/h.UGJ2mHY?tk=hT9adNgnBLH 买那个焊接好的+数据线 24r

1.28寸屏幕 淘宝链接:https://m.tb.cn/h.Uu9dn9Z?tk=9UUqdNgMyO8 21r

sd卡模块 淘宝链接:https://m.tb.cn/h.Uv1tHga?tk=fXYRdNgohfl 4.8r

sd卡 淘宝链接:https://m.tb.cn/h.Uu931E1?tk=BTpBdNgL3tV 买2GB带读卡器的 14.5r

杜邦线母对母 淘宝链接:https://m.tb.cn/h.Uu931E1?tk=BTpBdNgL3tV 10cm的 2.38r

杜邦线1母对2母 淘宝链接:https://m.tb.cn/h.Uu94eV0?tk=s4FcdNgKIkw一根1r需要两根

如果要播放图片请按照以下教程

把esp32板子连接到电脑上

打开计算机管理点击设备管理器

如果发现未知设备就缺少esp32的驱动程序cp210x,下载驱动并安装,链接:https://pan.baidu.com/s/1VSZH8Hntf1iyc5MoZn3KLA 提取码:1234

Arduino IDE 下载链接:https://www.arduino.cc

Arduino_GFX库 链接https://github.com/moononournation/Arduino_GFX/releases/tag/v1.0.5

下载后解压至C:\Users\用户名\Documents\Arduino\libraries\目录

JPEGDEC库https://github.com/bitbank2/JPEGDEC

下载后解压至C:\Users\用户名\Documents\Arduino\libraries\目录

打开Arduino IDE选择文件>首选项>附加开发板管理器网址 右侧的小图标

填入https://dl.espressif.com/dl/package_esp32_index.json

然后选择工具>开发板>开发板管理器

等它下载完索引之后在搜索框输入ESP32然后安装

安装完之后重启一下ArduinoIDE

选择esp32 dev module 开发板端口按照你设备的端口选

新建一个文件夹名字随便,位置随便

把库里面的ESP32_GC9A01.ino和JpegClass.h下载并放在该文件夹中

Arduino IDE打开保存的ESP32_GC9A01.ino文件

然后点击Arduino IDE>项目>上传

此时Arduino IDE会编译文件,等到下方窗口出现Connecting........(记住上传时一定要把sd卡拿出来)

等出现ping...就上传成功了

下面就是接线 屏幕连接开发板引脚 屏幕VCC对应开发板3v3 屏幕GND对应开发板GND 屏幕SCL对应开发板D14 屏幕SDA对应开发板D15 屏幕RST对应开发板D33 屏幕DC对应开发板D27 屏幕CS对应开发板D5 Micro SD卡模块连接开发板引脚(MOSI和SCK引脚是和屏幕共用的) SD卡GND对应开发板GND SD卡VCC对应开发板VIN SD卡MISO对应开发板D2 SD卡MOSI对应开发板D15(和屏幕共用用一母对二母的线) SD卡SCK对应开发板D14(和屏幕共用一母对二母的线) SD卡CS对应开发板D13

把SD卡用读卡器连接电脑,格式化成FAT32格式

在SD卡根目录创建img文件夹

把需要显示的图片用软件裁剪更改为240*240分辨率的jpg图片然后放到img文件夹里名字从0.jpg开始依次1.jpg,2.jpg

拔出读卡器把SD卡插到SD卡模块上把ESP32通电就行了

图片更换的时长在ESP32_GC9A01.ino的delay()里更改,单位毫秒,默认显示时长为5000毫秒

如果要播放视频请按照以下教程

前23步步骤一样

下载FFmpeg,下载+配置环境教程:https://zhuanlan.zhihu.com/p/141765024

完成第二步之后找一个比例是1.1的视频格式是MP4

在D盘新建video文件夹然后在里面新建img

把准备的视频放在video里面注意不要放到img里面

把视频名字改成1

按住win+r输入cmd在弹出的界面粘贴ffmpeg.exe -i D:\video\1.mp4 -r 30 -s 240x240 D:\video\img%d.jpg

把D:\video\img文件夹粘贴在sd卡根目录上即可

delay后面括号里的数改成0即可

拔出读卡器把SD卡插到SD卡模块上把ESP32通电就行了
