我在BrainTest()函数中遇到问题，当我加载它时，开始的文本不会出现在LCD上，它会直接显示到：

if (按钮== 0) { lcd.clear()； lcd.setCursor(0,0)； Lcd.print(“让我们开始”)； 延迟(1400)； lcd.clear()； lcd.setCursor(0,0)； Lcd.print(“测试”)；}

我还认为在函数的开头选择“是”或“否”是有问题的。

任何帮助都将不胜感激..。

如果你认为我应该改变问题中的任何东西，告诉我，我会改正的。另外，如果您发现我的代码有其他问题或升级，请告诉我，我会考虑它们。

。

现在，SelectApp()；函数运行良好，但在BrainTest()；函数中，第一个问题不起作用。我不能在答案之间切换..。

这是新代码

你处理这个按钮完全错误。在选择应用程序后，您有微秒的时间来释放按钮。所以看起来它被压了，因为它是。你从没检查过它是否被释放过。

我建议从超级简单的程序开始:数一下按钮被按了多少次，然后发送给串行程序。

除非你能让这个简单的按钮按下计数器，否则你就不能创建你想要创建的任何东西。
