C Arduino：如何解决计时器不能在4位7段显示器上正确显示数字的问题？
代码的作用：C Arduino：如何解决计时器不能在4位7段显示器上正确显示数字的问题？,c,arduino,arduino-uno,C,Arduino,Arduino Uno,代码的作用： 代码首先显示一个简短的“闪烁动画”，其中a-F段一次打开和关闭一个 “闪烁动画”持续3-10秒，计时器启动 计时器使用数字1和2从0-99秒开始计数，而数字3和4分别显示第100和第10秒（对不起，英语中的装置使用不当！基本上=100毫秒和10毫秒） 通过使用已连接的按钮，您可以通过按下它来停止计时器。计时器停止并显示时间 我的问题： 我面临的问题是，在闪烁的动画结束和计时器启动后，显示器将不会在数字2和3中显示单个数字，而是在计时器计数时显示大量数字。然而，我确实注意到，基本上，

大括号}
和b）您从不调用函数stopDisplay（）
.Hmm…噢！我会看一看，可能只是清理代码时的一个愚蠢的失误。我只想保留对我的问题至关重要的东西，同时保持整洁并消除任何干扰。有很多不必要的描述，不太清楚什么有效，什么无效。我编辑了问题。在代码中添加了“stopDisplay”部分并修复了大括号。我在“代码的作用”中发布的所有内容都有效。只是当数字显示在屏幕上时，它不会正确地显示它们。这个问题在“问题”一节中有更详细的解释。对于每个数字，您似乎要关闭所有段，然后只启用其中一个，然后延迟。此外，在choseDigit（）
中，您似乎将它们全部打开，然后关闭一个，尽管注释中显示的是相反的digital\u 1\u off//Display 1 on
。可见性最差的数字是其值变化最频繁的数字。你认为1/100秒变化的数字看起来有多清晰？但我并没有真正遵循逻辑。我不明白你为什么不连续写下所有的4位数字。还要注意的是，如果你一直启用和禁用，你会得到闪烁。
