主题中讨论的其他器件:CC3220SF、 SysConfig
大家好、我想在使用 CC3220SF Launchpad 时在 GPIO12/P3上触发中断。 我的目标是、一旦将引脚设置为接地、就会触发中断。 这是我在 SysConfig 上进行的设置

因此思路是在内部引脚连接到上拉电阻器、当我将引脚设置为接地时、会生成中断。 这是 SysConfig 通过 GUI 生成的配置

问题是该中断永远不会发生三态。 如果我在这里遗漏了一些东西、您可以提供建议吗? 我们使用的是 FreeRTOS

您好、Bilal:
您的 syscfg 设置看起来不错。 您是否在应用中初始化了驱动程序? 我建议进行测试、以查看 SDK 中的 GPIO 中断示例是否按预期工作、然后开始在代码中实现该示例。

您好!
我已经这么做了、也不起作用、按钮中断可以工作、但一旦我将其更改为 GPIO12、它就会停止工作、附加后您可以找到 SysConfig 和我修改过的示例文件

您好、Bilal:
我无法重现您的问题。 P03 (GP12)确实会在我的板中触发中断。 请尝试以下代码

当您将 P03接地时、这将打开或关闭红色 LED。 如果您在电路板中看不到这一点、请尝试使用另一个引脚、因为在这种情况下、这可能是硬件问题。
