Writing Your First "Hello World" Program

This guide will help you write and run your first "Hello World" program using Tiny Basic on the Arduino Due platform. It assumes that Tiny Basic for Arduino is already flashed onto the Arduino Due board.

Step 1: Connect the Arduino Due to Your Computer

  1. Use a USB cable to connect the Programming Port (labeled "PROGRAMMING" on the Arduino Due) to your computer. Ensure the cable supports both power and data transfer. The Programming Port is the USB port closest to the DC power jack.

  2. Identify the Serial Port:

    On Linux, open a terminal and run the following command to list connected devices: 

    ls /dev/tty*
    Look for a device like /dev/ttyACM0 or /dev/ttyUSB0. This is your Arduino Due's serial port.

Step 2: Access the Serial Interface

  1. Open a Serial Terminal. Use a terminal emulator like minicom, screen, or picocom. For example, to use screen, run: 

    screen /dev/ttyACM0 9600
    Replace /dev/ttyACM0 with the serial port identified earlier.

  2. Configure the Serial Terminal:

    • Set the baud rate to 9600.
    • Disable hardware flow control if prompted.

  3. Verify the Connection:

    • Press Enter in the terminal. You should see the Tiny Basic prompt (>).
    • Or, press RESET button in the Arduino Due. You should see the Tiny Basic version details and prompt (>).

Step 3: Write the "Hello World" Program

  1. Enter the Program: Type the following Tiny Basic code into the terminal: 
    10 PRINT("HELLO, WORLD!")
20 END

Step 4: Run the Program

  1. Execute the Program; at the Tiny Basic prompt, type: 

    RUN
    You should see the output: 
    HELLO, WORLD!

  2. Modify or Debug:

    • Use the LIST command to view the program: 

      LIST

    • Edit lines by re-entering them with the same line number.

Congratulations! You've successfully written and executed your first Tiny Basic program on the Arduino Due.
