      @m5stack Have you guys got any idea how to get the arducam esp32 examples working on the M5Camera (2nd version)?

      UIFlow, so easy an adult can learn it!
      If I don't know it, be patient!
      I've ether not learned it or am too drunk to remember it!

        // ArduCAM Mini demo (C)2017 Lee
// Web: http://www.ArduCAM.com
// This program is a demo of how to use most of the functions
// of the library with ArduCAM ESP32 2MP/5MP camera.
// This demo was made for ArduCAM ESP32 2MP/5MP Camera.
// It can take photo and send to the Web.
// It can take photo continuously as video streaming and send to the Web.
// The demo sketch will do the following tasks:
// 1. Set the camera to JPEG output mode.
// 2. if server receives "GET /capture",it can take photo and send to the Web.
// 3.if server receives "GET /stream",it can take photo continuously as video 
//streaming and send to the Web.

// This program requires the ArduCAM V4.0.0 (or later) library and ArduCAM ESP32 2MP/5MP camera
// and use Arduino IDE 1.8.1 compiler or above

          Hi, I have not tried ArduCAM. But once I'm free, I'll try that.

              Here's the pinmap about camera supplied by m5stack.

                That doesn't tie up because the arducams arduino_pin.h has D2 as I/O12
                and slave select as I/O17
