FastLED.h阻止ezButton.h

如何解决FastLED.h阻止ezButton.h

我正在使用Arduino来控制一个包含可寻址LED和按钮的项目。 我正在使用的库在标题中。 出于一个未知的原因，当我分别使用每个代码时，所有功能都可以正常工作，但是当我将它们组合在一起时，FastLED库会阻止按钮读取并导致奇怪的事情，例如双击或停止执行其他操作。

如何解决此问题？ （我试图消除delay（），但没有帮助） 预先感谢！

    There are two button types: Red and Blue.
    Red btn = -1
    Blue btn = +1

    On the machine's background there is an LED matrix which shows the user's progress.
    There are 4 levels (square frames) until one reaches the core and wins.

    The trick? The floor,which includes the buttons,is spinning.

解决方法

原因是，您使用了 delay() 函数。如果你使用延迟，一些按下的事件将被遗漏，不仅对于 ezButton，而且对于任何类型的按钮按下实现。 ezButton 已经有内部去抖动功能。
