How to configure GPIO interrupt in PE?

[rabbit]

Try to setup PTC18 as input, and causing interrupt at falling edge.

I am using PE to do setup, I can configure PTC18 as input, but I can't setup its interrupt at falling edge.

Hello,

I assume you are using Kinetis/ARM?

There is the ExtInt (External Interrupt) component you could use.

Additionally, other settings for a pin like pull-up/pull-down/interrupt edges are defined in the Init_GPIO component.

Have a look at this article:

Thanks. It is in Init_GPIO component.
