This article mainly introduces "how to configure ESP32CAM camera image real-time transmission". In daily operation, I believe many people have doubts about how to configure ESP32CAM camera image real-time transmission. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to configure ESP32CAM camera image real-time transmission". Next, please follow the editor to study!

I. Environmental configuration II. Video transmission.

Connect to esp32-cam using a usb to ttl: (be sure to connect the io0 to gnd)

1. Code

In your Arduino IDE, go to File > example > ESP32 > camera and open the CameraWebServer sample:.

# include "esp_camera.h" # include / WARNINGYOBY!

Use 'http://"); Serial.print (WiFi.localIP ()); Serial.println ("' to connect");} void loop () {/ / put your main code here, to run repeatedly: delay (10000);}

Before uploading the code, you need to modify the wifi that can be connected in the following variables:

Const char* ssid = "REPLACE_WITH_YOUR_SSID"

Const char* password = "REPLACE_WITH_YOUR_PASSWORD"

Then, make sure you select the correct camera module. I am using the AI-THINKER model.

Therefore, annotate all other models and uncomment the model:

/ / 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

To upload the code, follow these steps:

1) go to tools > motherboard, and then select AI-Thinker ESP32-CAM.

2) enter tools > Port, and select the COM port to which ESP32 is connected.

3) then click the upload button to upload the code.

The upload will be successful soon. If the upload is not successful or cannot be connected, please make sure that the wiring is correct and whether the io0 is connected to gnd.

two。 Get the web address

You can get the URL through the serial port. Just paste the URL into the browser. Be sure to be in the same LAN as your computer.
