How to use GPIO 09, GPIO 10 nrf52840 as GPIO interrupt

[John Nguyen]

Dear support team,

I would like to use GPIO 09/10 as a GPIO interrupt.

I just searched and I see that need to define CONFIG_NFCT_PINS_AS_GPIOS.

But I can't do it. Please help!

P/s: I use nrf52840 with segger embedded.

Thanks and regards,

I mean when I defined CONFIG_NFCT_PINS_AS_GPIOS, my code still doesn't work.

Can I put this code in main.c, before init gpio, right?

Thanks,

John N

Hi John,

How have you defined CONFIG_NFCT_PINS_AS_GPIOS?

You should add this to the preprocessor definitions in SEGGER Embedded Studio. You can do so by doing the following: Go to Project > Edit Options > Code > Preprocessor > Preprocessor Definitions and add CONFIG_NFCT_PINS_AS_GPIOS there.

Best regards,

Marte

Hi, could you help me this issue?

My issue is when I pressed the button, the GPIO interrupt does not happen.

I am sure that my hardware is worked. Because when I change to another pin, GPIO interrupts worked fine.

Thanks,

John
