有些家庭的日程安排很复杂：孩子们有上学活动和放学后的活动，你想要记住的重要事情，每个人都有多个约会等等。虽然你可以使用手机和应用程序来关注所有事情，但在家中放置一个大型低功耗显示器以显示家人的日程不是更好吗？电子墨水日程表刚好满足！

### 硬件

这个项目是作为假日项目开始，因此我试着尽可能多的旧物利用。其中包括一台已经闲置了太长时间树莓派 2。由于我没有电子墨水屏，因此我需要购买一个。幸运的是，我找到了一家供应商，该供应商为支持树莓派的屏幕提供了 [开源驱动程序和示例][4]，该屏幕使用 [GPIO][5] 端口连接。

我的家人还想在不同的日程表之间切换，因此需要某种形式的输入。我没有添加 USB 键盘，而是选择了一种更简单的解决方案，并购买了一个类似于在 [这篇文章][6] 中所描述 1x4 大小的键盘。这使我可以将键盘连接到树莓派中的某些 GPIO 端口。

最后，我需要一个相框来容纳整个设置。虽然背面看起来有些凌乱，但它能完成工作。

### 软件
我从 [一个类似的项目][8] 中获得了灵感，并开始为我的项目编写 Python 代码。我需要从两个地方获取数据：
* 天气信息：从 [OpenWeather API][9] 获取

* 时间信息：我打算使用 [CalDav 标准][10] 连接到一个在我家服务器上运行的日程表

由于必须等待一些零件的送达，因此我使用了模块化的方法来进行输入和显示，这样我可以在没有硬件的情况下调试大多数代码。日程表应用程序需要驱动程序，于是我编写了一个 [Pygame][11] 驱动程序以便能在台式机上运行它。

编写代码最好的部分是能够重用现有的开源项目，所以访问不同的 API 很容易。我可以专注于设计用户界面，其中包括每个人的周历和每个人的日历，以及允许使用小键盘来选择日程。并且我花时间又添加了一些额外的功能，例如特殊日子的自定义屏幕保护程序。

最后的集成步骤将确保我的日程表应用程序将在启动时运行，并且能够容错。我使用了一个基本的 [树莓派系统][13] 镜像，并将该应用程序配置到 systemd 服务，以便它可以在出现故障和系统重新启动依旧运行。

2021-03-18 10:10:48 +08:00
做完所有工作，我把代码上传到了 [GitHub][14]。因此，如果你要创建类似的日历，可以随时查看并重构它！
### 结论
日程表已成为我们厨房中的日常工具。它可以帮助我们记住我们的日常活动，甚至我们的孩子在上学前，都可以使用它来查看日程的安排。

对我而言，这个项目让我感受到开源的力量。如果没有开源的驱动程序、库以及开放 API，我们依旧还在用纸和笔来安排日程。很疯狂，不是吗？
