ESP32S3-Cam实践(CameraExample)

0.参考

        esp32idf 关于SPIRAM的使用

        以ESP Component espressif/esp32-camera组件的example为工程进行实践。

1.挂载OV2640

        改动1：按主程序文件头部的指导（Setup），在SDK Configuration Editor中确认一下配置。

        改动2：按主程序文件头部的指导（Setup），替换成自己使用的板子。

#include "esp_camera.h"

#define BOARD_ESP32S3_GOOUUU 1

        改动3：改变一下SPI RAM Mode

2.Build,Flash and Monitor

监视器输出，GoodGood
