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

[costaud]

为什么不直接用第一个函数的初始化代码 ？

[qq4056]

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.

[qq4056]

没有产生中断，不知道什么原因

[Xiong Yu]

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?
