Barcode Scanner Application using SAM E51 Integrated Graphics & Touch (IGAT) Curiosity Evaluation Kit

Download

Description:

This application detects the EAN-13 barcode and decodes it with the help of the ArduCAM Mega camera module. The ArduCAM Mega captures an image with a resolution of 1920x1080 and stores the image in an internal memory. The decoded barcode is then displayed on the serial console and graphical display.

Hardware Used:

• SAM E51 Integrated Graphics & Touch (IGAT) Curiosity Evaluation Kit
• ArduCAM Mega 3MP Camera Module or ArduCAM Mega 5MP Camera Module with Autofocus

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_e51_igat

• Refer the Release Notes to know the MPLAB® X IDE and MCC Plugin version. Alternatively, Click Here
• Any Serial Terminal application like Tera Term terminal application.

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

Setup:

• Connect the ArduCAM Camera module to the SAM E51 Integrated Graphics & Touch (IGAT) Curiosity Evaluation Kit as shown below.
  

  

• Connect the ArduCAM pins directly to the Extra Port pins interface (J203). i.e.
  

• Connect a micro-USB cable to the DEBUG USB port of the SAM E51 Integrated Graphics & Touch (IGAT) Curiosity Evaluation Kit to power the board and for programming and debugging.

  

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 “ATSAME51J20A”
• 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 (same51_barcode_scanner/firmware/sam_e51_igat.X) in MPLAB® X IDE
• Ensure “SAM E51 Integrated Graphics & Touch Curiosity” 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
• Debugging the project can be done by clicking on the “Debug Main Project” button in MPLAB® X IDE tool bar
• Follow the steps in “Running the Demo” section below.

Running the Demo:

• Open a standard terminal application on the computer (like Putty or Tera Term) and configure the virtual COM port.
• Set the serial baud rate to 115200 baud in the terminal application.
• Wait for the initialization prints in the serial port terminal. If it does not show any prints, give the command “0” through terminal console which resets the development board.
• When the ArduCAM Mega Camera is enabled in the demonstration, wait for the initialization confirmation from the development board. This will be printed on the serial port terminal.
• Show the Barcode in front of the camera for capture (maintain a minimum distance of 10 to 15 cm).
• Give the command “1” through terminal console.
  • An LED “LED0” on the SAM E51 Integrated Graphics & Touch (IGAT) Curiosity Evaluation Kit toggles when the scanning is in progress.
• Once the scanning is completed, the result will be displayed in the terminal console as well as graphical display also.

Output:

Note: - This demo supports EAN-13 barcodes only. - Print the EAN-13 type barcode on a A4 sheet and show it before the ArduCAM Mega Camera module (keep a distance of 10 to 15 cm).
