Hello!

Thank you for reaching out with your questions about integrating a temperature sensor with the Toradex Mallow Carrier Board. I’m happy to guide you through the process.

  1. Remote Access via SSH:
    To enable SSH access, ensure your Mallow Carrier Board is connected to your network. SSH is typically enabled by default on TorizonCore. You can access the terminal using the command ssh torizon@<board-ip-address>, replacing <board-ip-address> with your board’s actual IP address.

  2. GPIO Pin Access for Sensor Integration:
    For accessing GPIO pins, you can use the gpiod library in Python. First, ensure the library is installed in your Python environment. You can control GPIO pins by accessing them through the /dev directory in Torizon. Here’s a basic example:

    import gpiod
chip = gpiod.Chip('gpiochip0')
line = chip.get_line(23)  # Replace 23 with your GPIO line number
line.request(consumer='myapp', type=gpiod.LINE_REQ_DIR_OUT)
line.set_value(1)  # Set GPIO high

  3. Running Python Scripts for Data Processing:
    TorizonCore is well-suited for running Python applications. You can use the Torizon IDE extension to set up your development environment, which helps manage dependencies and containerize your application for deployment.

  4. OS Recommendation:
    TorizonCore with Docker is recommended for your project as it simplifies application deployment and management, especially for Python-based applications. It supports containerization, which is beneficial for managing dependencies and updates.

  5. Power Specifications:
    The Mallow Carrier Board typically requires a 5V power supply. Ensure your power source can provide sufficient current, usually around 2A, to support the board and any connected peripherals.

  6. Basic GPIO Access Examples:
    The example provided above demonstrates basic GPIO control using Python. For more complex interactions, you can explore further documentation on GPIO and peripheral access.

I hope this helps you get started with your sensor integration project on the Toradex platform. If you have more questions, feel free to ask!

Best regards,
