Motion Surveillance Application on SAM E54 Curiosity Ultra Development Board

Download

Description:

The Motion Surveillance application detects a motion in front of the ArduCAM (camera) using the PIR Click (motion sensor) board. ArduCAM captures an image with resolution 320x240 and stores the image in an external storage device (microSD Card). Additionally, the application demonstrates a live preview of captured images.

The live preview of captured images is demonstrated by running an HTTP web server on the development board. The user connects to the webserver through an internet browser and view the live preview of the captured images.

Hardware Used:

Software/Tools Used:

This project has been verified to work with the following versions of software tools:

Refer Project Manifest present in harmony-manifest-success.yml under the project folder firmware/src/config/sam_e54_cult_freertos

Because Microchip regularly update tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project doesn’t seem to work and version incompatibility is suspected, It is recommended to double-check and use the same versions that the project was tested with. To download original version of MPLAB Harmony v3 packages, refer to document How to Use the MPLAB Harmony v3 Project Manifest Feature

Hardware Setup:

TCP/IP Network Setup:

To run the webserver component in the demo application, the target development board and the host computer should be in the same network. The host computer can be connected to a router via an ethernet cable or Wi-Fi. The target board should be connected to the router via an ethernet cable. Please refer to the following connection diagram.

  1. The application is configured and build with LAN8740 PHY driver. To use a different PHY, use MPLAB® Code Configurator (MCC) to select and configure the PHY. Make sure that correct PHY address and configuration flags are used for the particular PHY daughter board. The MII/RMII and I/O configuration flags should match the hardware for the PHY board. This application demonstration assumes that IPv4 is enabled. If IPv4 is not enabled in MCC, the code in app.c will not build and needs to be updated to remove the IPv4 dependencies.

  2. The demo has DHCP enabled, and expect a DHCP server to be available. If there is no DHCP server, then the default static IP address will be used: 192.168.100.11. If this static address does not match your network settings, use MPLAB® Code Configurator (MCC) to modify the static IP address of the network interface.

  3. The NetBIOS name of the application is specified during the initialization of TCP/IP stack. It is the hostName member of TCPIP_HOSTS_CONFIGURATION structure. The NetBIOS service must be enabled in demonstration configuration, for the demonstration to respond to NetBIOS queries. Alternatively, use the IPv4 or IPv6 address (if IPv6 is enabled) of the board directly.

  4. The IPv4 and IPv6 addresses can be obtained by running the TCP/IP Discovery utility on the computer. Ex: ipconfig

Programming hex file:

The pre-built hex file can be programmed by following the below steps.

Steps to program the hex file

  • Open MPLAB X IDE
  • Close all existing projects in IDE, if any project is opened.
  • Go to File -> Import -> Hex/ELF File
  • In the “Import Image File” window, Step 1 - Create Prebuilt Project, Click the “Browse” button to select the prebuilt hex file.
  • Select Device has “ATSAME54P20A”
  • Ensure the proper tool is selected under “Hardware Tool”
  • Click on Next button
  • In the “Import Image File” window, Step 2 - Select Project Name and Folder, select appropriate project name and folder
  • Click on Finish button
  • In MPLAB X IDE, click on “Make and Program Device” Button. The device gets programmed in sometime
  • Follow the steps in “Running the Demo” section below

Programming/Debugging Application Project:

  • Open the project (same54c_motion_surveillance/firmware/sam_e54_cult_freertos.X) in MPLAB X IDE
  • Ensure “SAM E54 Curiosity Ultra” is selected as hardware tool to program/debug the application
  • Build the code and program the device by clicking on the “Make and Program Device” button in MPLAB X IDE tool bar
  • Follow the steps in “Running the Demo” section below

Running the Surveillance application demo:

  • Perform “Hardware Setup” steps mentioned above, if not done already.
  • Ensure a microSD Card is formatted and loaded with the web_pages provided within the same54c_motion_surveillance/firmware/src/web_pages directory.
  • Build and download the demonstration project on the target board.
  • Serial Terminal Configuration:
    • Open a standard terminal application on the computer (like Hyper-terminal or Tera Term) and configure the virtual COM port.
    • Set the serial baud rate to 115200 baud in the terminal application.
    • See that the initialization prints on the serial port terminal.

    • When the DHCP client is enabled in the demonstration, wait for the DHCP server to assign an IP address for the development board. This will be printed on the serial port terminal.

    • Alternatively: Use ipconfig to get the IP address of the board and ping to test if the device is reachable.
  • An LED “LED2” on the SAM E54 Curiosity Ultra Development Board toggles when a motion is detected in front of the motion sensor (PIR click).
  • An JPEG format image with 320x240 resolution is captured and stored on the microSD Card. Check the logs in the terminal for the motion detection, start capture and saved image events.
  • Steps to preview the captured images:
    • Step 1: Live streaming of captured images:
      • An HTTP server is hosted by the demonstration application. Open a web browser and direct it to the board running the HTTP server by typing the URL in the address bar (for example, https://mchpboard_c or by entering the assigned IP address i.e. http://192.168.100.11/ in the URL bar), and then press Enter key.
      • On the loaded page, Go to the Motion Surveillance under the left Menu.
      • The following image shows how the Motion Surveillance page looks. When the motion sensor detects a motion, the captured images will be live previewed on this page.

      • Note:
        • When the motion sensor detects a motion, the ArduCAM captures an image (resolution 320x240) and stores in web_pages/arducam folder on the microSD Card.
        • The maximum number of images that the application stores on the microSD Card is 255. If the number of images captured exceeds 255, the application overwrites the images from the beginning. User can increase the storage size based on the available free size of the microSD Card by changing the MAX_FILE_NAMES macro in the app_ardu_cam.h header file.

        • If any error (check logs in the terminal), reset the device or reload the page or click Motion Surveillance menu option.
    • Step 2: Preview the images stored on the microSD Card using Windows Photo Viewer application:
      • Remove the microSD Card from the J704 socket (back side of the board) on SAM E54 Curiosity Ultra Development Board and insert into personal computer.
      • Goto web_pages/arducam folder and preview the captured images using any photo preview application.
