LPC11U68 interrupts for buttons

Guy_mego — Thu, 18 Aug 2022 13:02:38 GMT

Hi All,

I defined my buttons as GPIOs, I want to get an interrupt when button is being pressed.
I can't find how to connect a GPIO to an interrupt.

I work on LPC11U68 board.

Does any one how should i connect my button that i will get an interrupt what its state is changed?
released -> pressed -> released.

Thanks in advance.

Best Regards,
Guy.

Hi,

I would recommend you to use the LPCOpen libraries available in this link. You will find several examples to help you with your development.

I hope this helps, Daniel.

Hi,
I checked the examples and didn't find a solutions that assist me with my issue.
I also trying to search an answer in the forum but didn't find any.
I know how to work with interrupt but as I said, I don't know to connect a GPIO to an interrupt.

Hi,

I would recommend you to use as a reference any LPCOpen example that implements interrupts to see how an interrupt is enabled.

I also recommend you to take a look to chapter 3, 7, 8 and 9 of the User Manual.

I hope this helps, Daniel.
