樹莓派介紹

• 講義
• 影片

• 樹莓派(RaspberryPI)是由英國營利組織的樹莓派基金會(Raspberry Pi Foundation)所開發的一片信用卡般大的電路板，搭載處理器（ARM CPU）和Linux系統，以 SD 卡為硬碟，目的是以低價硬體及自由軟體刺激學校的電腦科學教育。樹莓派有開放許多的GPIO(General Purpose Input Output)腳位可以連接許多週邊硬體電子零件。

  • Synchronizing Time on Raspberry Pi

    Using timedatectl

    Check Current Time Settings
    Open the terminal and run:

    timedatectl

    This command shows the current time settings and whether NTP (Network Time Protocol) is enabled.

    Enable NTP Synchronization
    To enable automatic time synchronization, use:

    sudo timedatectl set-ntp true

    Verify NTP Status
    After enabling, check the status again with:

    timedatectl

    Ensure that "NTP service" is active.

    Configuring NTP Servers

    If you want to change the NTP server:

    1.Edit the configuration file:

    sudo nano /etc/systemd/timesyncd.conf

    2.Modify the FallbackNTP line to your preferred server, for example:

    FallbackNTP=time.nist.gov

    3.Restart the NTP service:

    sudo systemctl restart systemd-timesyncd

    Conclusion

    By following these steps, you can ensure that your Raspberry Pi maintains accurate time through network synchronization. This is essential for various applications, especially those requiring precise timestamps.
