如何将 Wiimote 连接到计算机来控制音频播放器？

我想连接 Wiimote。我正在运行 natty，想用我的 Wiimote 控制音频播放器。可以吗？

编辑：林兹温德向我透露了一个名为“威肯“。显然，它是作为指示器小程序实现的，并允许自定义您的 wii 操作。您可以将其绑定amarok -t到 wiibutton。

你很幸运，你甚至不知道自己有多幸运。我花了一段时间做了一些研究，但：不久前我写了一个脚本来实现这一点。它适用于 Amarok 和 Totem，但可以轻松修改它以控制其他玩家（前提是他们有命令行界面）。给我几分钟时间写几条评论。然后我会编辑这个答案并发布它。

  • 特征：
    • 检查 Wiimote 的电池状态。
    • 打开 Wiimote 上的 LED。
    • 启动 Amarok。
    • 暂停/继续播放。
    • 跳至下一曲目/最后一曲目。
    • 通过 alsamixer 控制系统音量

你需要 Python 和python-cwiid 安装 python-cwiid/sudo apt-get install python-cwiid已安装。您可以在等待时执行此操作。

以下是脚本。只需在终端中运行它即可。

"""A Wiimote script to control totem and amarok under Ubuntu.

Provides a rudimentary interface to:
-Check battery status of the Wiimote.
-Switch an led on the Wiimote.
-Start Amarok.
-Pause/contiue playing.
-Skip to next/last track.
-Control the system volume over pulseaudio

Needs the package 'python-cwiid', 'amarok' and or 'totem' to be installed.

系统托盘中还有一个 GUI 程序，名为“威肯“我曾经在 11.04 (Natty) 之前的 Ubuntu 版本上使用过它，但现在我似乎不知道如何使用位于https://launchpad.net/wiican

它只是按照你的意愿连接和配置按钮，虽然不完美，但我会称它为很棒

一旦我找到如何安装的方法，就会更新帖子。

编辑：我可以在这里找到一个包关联
