我正在尝试让 MSP430 上的红灯在装配中每次按下按钮时逐渐闪烁
I am trying to make the red light on an MSP430 blink incrementally for each button press in Assembly
我试图让 MSP430 上的灯在每次按下按钮时闪烁，并跟踪按钮被按下的次数。例如，按下一个按钮将闪烁一次，然后按下一个按钮将闪烁两次等。我已经生成了使灯响应按钮按下的代码，以及使灯闪烁的代码，但是我无法将两者结合起来使灯仅闪烁一定次数。

我试图将这两段代码结合起来，但它只会导致闪烁的灯光，我可以通过按下按钮在循环之间切换。我对 IAR 中的寄存器递增也有疑问。当我单步执行调试器时，它会在按下按钮时递增 R8，但是，当我简单地按下转到 运行 程序时，它不会在寄存器菜单中递增。任何正确方向的想法、评论或指示将不胜感激。
注意：虽然我知道这在 C 中可以更容易地实现，但我必须在 Assembly 中实现。
所以我终于想通了。事实证明，IAR 不会在 Go 命令上动态更新寄存器，而只会在单步执行时更新。我发现这一点是因为在我结束并重新启动程序后，寄存器会增加。这意味着代码工作正常，但没有实时显示。在我相信代码是正确的之后，我实施了其余的增量闪烁功能，并最终收到了一些按预期执行的工作代码。再次感谢那些花时间尝试帮助我的人。
