关于这个项目

在浏览 Hackaday.io 时，我遇到了一个漂亮的时钟，它由 Frugha 的一系列 7 段显示器制成。我真的很想构建这个，但 Frugha 的版本非常大，因为它使用 0.56" 7 段显示器。我的设计使用 0.28" 7 段显示器，使它只有四分之一的尺寸。

软件经过重新编写，包含闹钟和用于设置时间、日期和闹钟的配置屏幕。

配置画面

时钟由四个按钮控制。 SELECT 按钮（最顶部）将显示配置屏幕。当前选择将闪烁。再次按下 SELECT 按钮将在不同的配置部分（即时间、日期、闹钟、调谐、亮度、日期格式和时钟）之间循环。

在选择菜单项之一时按 ENTER 按钮（从顶部向下第二个）将允许您更改其设置。如果菜单项有多个设置，则 ENTER 按钮将在它们之间循环。活动设置将闪烁。

当设置闪烁时，UP 和 DOWN 按钮（底部两个按钮）将更改设置。

日期画面

在显示时钟时按 ENTER 按钮（从上数第二个）将显示日期屏幕 5 秒钟。

配置屏幕上的日期格式部分允许您设置日期格式（DD-MM 或 MM-DD）和使用的字体。

设计注意事项

为了简化电路板设计，我的版本使用 4 位显示而不是原始版本中使用的个位显示。由于 0.28" 显示器很小，我不得不将 MAX7219 芯片放在单独的板上。为了简单接线，使用机械加工的公母排针连接板，

如果您希望将电路板商业制造或像我一样自己制作电路板，则已包含 Eagle 文件。我用碳粉方法制作我的。

柱板

需要制作六个容纳所有显示器的柱板。焊接公机头时，从中间组开始，向外边缘工作。使用火柴棒或类似的东西来充分抬起插座，以便您可以轻松焊接引脚。使用尖端细的小烙铁和 0.5mm 焊锡。

创建列模块后，我建议您使用哑光黑色涂料绘制显示边框。如果显示器与其邻居不完全对齐，这将停止显示白色边缘。同样使用记号笔，为每个列模块编号。这有助于将它们插入 MAX7219 主板。

MAX7219主板

在设计主板和列板时，我没有将正确的 MAX7219 段或数字映射到相应的显示引脚。我想让 PCB 布局尽可能简单，并根据软件的任何差异进行调整。

我建议当涉及到母机加工插座时，您首先将它们放在柱板的公针上，然后在连接时将组件焊接到位。这意味着柱销将与其对应的插座完全对齐。如果您需要移除它们，对色谱柱模块进行编号将确保它们回到相同的位置。

MPU板

微处理器板包含所有其他组件。四个按钮和两个 SMD 电容器安装在板的背面，所有其他组件都安装在板的正面。为了保持低调，通常焊接到 Arduino Pro Mini 的 FTDI 排针现在直接焊接到 PCB 上。两条线从 DTR 和 VCC 引脚直接向下连接到 PCB。

制作案例

包括正面和背面的 STL 文件。两者都使用 0.2 层高和边缘打印。正面还启用了仅接触构建板的支撑。

MAX7219 主板及其列模块从正面滑入。如果你觉得它有点松，用一两层美纹纸胶带包装。

MPU板热粘在背面。

软件

该软件要求 MD_MAX72XX 库已安装在您的 Arduino IDE 中。我已经提供了我的 Hardware_Test_V1 草图进行测试。它将点亮每个段，以便您检查短路或断线。一旦显示工作，上传Clock_V4草图。
