复制代码

4.修改上述程序中wifi的ssid、password,为您所在网络wifi的ssid与密码

  1. const char* ssid = "xiaogui";
  2. const char* password = "88888888";
复制代码



5.修改camera_pins.h文件,增加如下代码:

  1. #elif defined(CAMERA_MODEL_DFRobot_FireBeetle2_ESP32S3)
  2. #define PWDN_GPIO_NUM     -1
  3. #define RESET_GPIO_NUM    -1
  4. #define XCLK_GPIO_NUM     45
  5. #define SIOD_GPIO_NUM     1
  6. #define SIOC_GPIO_NUM     2
  7. #define Y9_GPIO_NUM       48
  8. #define Y8_GPIO_NUM       46
  9. #define Y7_GPIO_NUM       8
  10. #define Y6_GPIO_NUM       7
  11. #define Y5_GPIO_NUM       4
  12. #define Y4_GPIO_NUM       41
  13. #define Y3_GPIO_NUM       40
  14. #define Y2_GPIO_NUM       39
  15. #define VSYNC_GPIO_NUM    6
  16. #define HREF_GPIO_NUM     42
  17. #define PCLK_GPIO_NUM     5
复制代码

6.修改相应设置,如下图所示

8.打开串口监视器,查看启动信息

基于FireBeetle 2 ESP32-S3和行空板的无线图传相机图7

从串口监视器可看到:“Connect to WiFi”、“WiFi connected”、“Camera Ready! Use 'http://192.168.2.234' to connect”等信息,记住这个IP地址。通过这个IP地址就可以访问摄像头了。

9.OV2640设置
在浏览器中,输入刚才记住的IP地址,如192.168.2.234,即可打开设置页面。修改相应的选项,可以对摄像头进行设置。
