M5StackCoreS3_CameraWebServer

日本語

Overview

Porting of espressif/arduino-esp32 example CameraWebServer to M5Stack CoreS3 (GC0308).
Access CoreS3 from a browser via WiFi to control the camera and receive streaming.
It can also perform QR recognition.

Required

  • M5Unified
  • esp32-camera
    However, If you set platform = espressif32 and framework = arduino in platformio, esp32-camera is included in the package, so you do not need to specify esp32-camera in lib_deps.
  • gob_GC0308
  • WiFi connection available

Build type

Env Description
release Basic settings and QR recognition
release_face Support face detection and recognition

How to use

Once executed, the IP address will be displayed on the screen and on the serial monitor.
(This is an example, so the actual IP will vary depending on the environment.)

 setup(): Camera ready use: http;//192.168.1.20 to connect

Access that IP address from your browser.

When WiFi connection fails

The connection is made as follows, assuming that CoreS3 has the SSID / Password of the already connected it stored.

// main.cpp
    WiFi.begin(); // Connects to credential stored in the hardware.

Please save the credential in some way or rewrite the source.

// main.cpp
    WiFi.begin("Your SSID", "Your password");
