使用一个usb转ttl连接esp32-cam:(切记一定要将io0接gnd)
在您的Arduino IDE中,转到文件>示例> ESP32 >相机并打开CameraWebServer示例:。

Use 'http://"); Serial.print(WiFi.localIP()); Serial.println("' to connect"); } void loop() { // put your main code here, to run repeatedly: delay(10000); }
在上传代码之前,您需要在以下变量修改可以连接的wifi:
const char* ssid = “REPLACE_WITH_YOUR_SSID”;
const char* password = “REPLACE_WITH_YOUR_PASSWORD”;
然后,确保选择正确的相机模块。我使用的是AI-THINKER模型。
因此,请注释所有其他模型,并取消注释该模型:
// Select camera model
//#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
//#define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM
#define CAMERA_MODEL_AI_THINKER // Has PSRAM
//#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM
要上传代码,请按照以下步骤操作:
1)转到工具>主板,然后选择AI-Thinker ESP32-CAM。
2)进入工具>端口,选择ESP32连接的COM端口。
3)然后,点击上传按钮上传代码。
不久之后就会上传成功,如果上传不成功或者连接不了,请确认接线是否正确,是否将io0连接gnd
