-This example assumes you have already set up all the tools necessary to compile Rust for ESP32.
-
-When run using `cargo run`, it will compile and flash the program to an ESP32-CAM mounted on an
-ESP32-CAM-MB board connected via USB to the host machine.
-
-The program will:
-
-1. Initialize the onboard OV2640 camera as well as the bright white LED (flash).
-2. Turn on the flash.
-3. Take a jpeg-encoded picture using the camera.
-4. Print information about the image: width, height and size in bytes.
-5. Enter deep sleep for 60 seconds, after which the device starts the process.
