要实现在ESP32上使用3.2英寸SPI TFT LCD显示JPEG图像，您需要准备的硬件包括ESP32、3.2英寸SPI TFT LCD、Adafruit库、SPIFF和JPEG解码器。首先，确保您的ESP32配置了正确的IO引脚以实现高速SPI通信。在开始操作之前，请确保您已安装所需的库。在Arduino IDE中，打开“Sketch”菜单，选择“Incl
方法一:通过Arduino IDE 2 的安装方法 1,点击Library 2,搜索框输入「GFX Library for Arduino」 3,点击「INSTALL」进行安装 4,安装完成后,该库的名称旁边会显示「INSTALLED」 方法二:GITHUB 仓库下载安装方法 1,首先到GITHUB下载「GFX Library for Arduino」:https://github.com/moononournation/Arduino_GFX 2,...

硬件要求:屏幕支持 JPEG 直接写入(如 ILI9341 需特定驱动)。 步骤: 转换视频为 MJPEG: ffmpeg -i input.mp4 -vf "fps=10,scale=240:240" -c:v mjpeg output.mjpeg 存储视频:将 MJPEG 文件存入 SD 卡或通过 WiFi 传输。 解码显示:使用ESP32-TFT-Library或LVGL逐帧解码并显示。 示例代码结构: #include <...
