  97.  
  98.     //remove isr handler for gpio number.
  99.     gpio_isr_handler_remove(GPIO_NUM_4);
  100.     //hook isr handler for specific gpio pin again
  101.     gpio_isr_handler_add(GPIO_NUM_4, gpio_isr_handler, (void*) GPIO_NUM_4);
  102. }
  103.  
  104. 我的问题是:如何把test_PT_GpioInit()配置成和PT_GpioInit()一样,实现IO口中断功能?谢谢

为什么不直接用第一个函数的初始化代码 ?

我想用不同的方式实现IO的中断功能。你知道我哪里错了吗?

第二段代码的现象是什么?不能产生中断吗? 触发源是什么? 如果是 18 和 19 的话试着使能一下 18, 19 的上拉模式.

没有产生中断,不知道什么原因 :shock:

麻烦你把问题再描述下, 提供下你的需求,以及目前的状态:
1. 哪一个IO无法产生中断?
2. 两个case的作用分别是什么?
3. 你是如何判断中断配置没有生效的?
4. example 能满足你的需求嘛?
