      Hi all, I can upload and run the camera.ino Arduino sketch on GitHub setting OPI PSRAM in tools menu in Arduino IDE 2.3.4.

      I wolud like now to try this project ESP32-CAM Take Photo and Display in Web Server but without any joy!!

      /*********
  Rui Santos
  Complete project details at https://RandomNerdTutorials.com/esp32-cam-take-photo-display-web-server/
  
  IMPORTANT!!! 
   - Select Board "AI Thinker ESP32-CAM"
   - GPIO 0 must be connected to GND to upload a sketch
   - After connecting GPIO 0 to GND, press the ESP32-CAM on-board RESET button to put your board in flashing mode

      I know this example is made for AI Thinker ESP32-CAM but changing camera_pins is not enough...

      some tips?

      best regards

          why don't you try this example? https://github.com/m5stack/M5AtomS3/blob/main/examples/Basics/camera/camera.ino

          Good morning, and welcome to the Black Mesa Transit System.

            @kuriko thanks for the reply, as I wrote on post n. 1,

            @cepics said in AtomS3R Camera & esp_camera.h example:

            I can upload and run the camera.ino

            for my project I need to take picture and display it in a web page....
