help with IRQ_CONNECT(nrf52840)

[teijokk]

Is there possible to attach gpio pin to ext interrupt using IRQ_CONNECT() ? Or is there a way to use EXTI irqs?

No, IRQ_CONNECT() is just for generating interrupt vectors (see https://docs.zephyrproject.org/latest/reference/kernel/other/interrupts.html#implementation for details). A SoC GPIO driver would use IRQ_CONNECT() for "attaching" a function to an IRQ vector.

GPIO interrupt callbacks can be attached using the GPIO API: https://docs.zephyrproject.org/latest/reference/peripherals/gpio.html
An example of using this API can be found in the button sample: https://github.com/zephyrproject-rtos/zephyr/blob/master/samples/basic/button/src/main.c
