这个是官方GPIO中断例程，按键触发中断后，会一直不断的进入中断，不知道怎样改，使每次触发中断后，只产生一次中断。
程序中设置的是下降沿中断，照理应该只产生一次中断。

现在有一个正在开发的项目，使用的是HC32L110芯片，用IO口检测交流电源50HZ的过零信号去触发可控硅。GPIO中断搞不定，项目没法进行下去了。望各位高手指点！

Q80351951 发表于 2023-9-25 08:36

一直中断大概率就是中断标志没清掉

wlm3000 发表于 2023-9-25 11:09

中断口是P3.3阿

xch 发表于 2023-9-25 12:42

void Gpio_IRQHandler(uint8_t u8Param)
{
    *((uint32_t *)((uint32_t)&M0P_GPIO->P3ICLR + u8Param * 0x40)) = 0;
      
    SK_LED_SET(0);
    delay1ms(500);
    SK_LED_SET(1);
    delay1ms(500);
      
}
===========================
看起来不像原厂的

你要透过表象，理解本质。
要么你改成P0CLR,要么去掉后面的u8Param*0x40.二选一，你自己看着办

gaoyang9992006 发表于 2023-9-25 19:27

这个程序风格，看了头大。

wlm3000 发表于 2023-9-26 13:20

改了后，功能正常了

小夏天的大西瓜 发表于 2024-3-26 20:50

应该还是中断的设置问题

kmnqhaha 发表于 2024-4-30 17:12

这个单片机市场用的多吗？

typedef struct {
    uint8_t u8Port;
    uint8_t u8Pin;
}stc_gpio_list_t;
和
const stc_gpio_list_t gGpiolist[] =
{
    /*{ 0, 0 }, */{ 0, 1 }, { 0, 2 }, /*{ 0, 3 },*/
    { 1, 4 }, { 1, 5 },
    { 2, 3 }, { 2, 4 }, { 2, 5 }, { 2, 6 },
    { 2, 7 },
    { 3, 1 },
    { 3, 2 }, { 3, 3 }, { 3, 4 }, { 3, 5 }, { 3, 6 },


};
这段好像没用到啊，有啥作用吗？

probedog 发表于 2025-7-31 15:47

按键抖动？机械按键在按下/释放时会产生毛刺信号，导致多次触发中断。

onlycook 发表于 2025-7-31 15:50

在中断处理函数中临时禁用中断，处理完成后重新启用。

七毛钱 发表于 2025-7-31 15:51

每次进入中断时清除标志位。

内政奇才 发表于 2025-7-31 15:51

启用内部上拉电阻，防止引脚悬空。

classroom 发表于 2025-7-31 16:48

中断标志未正确清除。

flycamelaaa 发表于 2025-7-31 16:48

可能是中断配置问题。
