nrf52840 gpio interrupt setting issue

[EthanZhao]

Hi there,

There are some problems when setting nrf52840 GPIO interrupt.  When I use gpio_pin_interrupt_configure_dt api to configure 11 gpio pins then download to my customer board.

After all,  I will get an Error number (Not enough core) on log when I configure more then 7 gpio pins interrupt.

How can I fix this problem?

thanks

Hello

The nRF52840 only has 8 GPIO event channels, which is probably why you run into problems trying to define interrupts for many pins.

You can get around this by using port events rather than pin events.

Best regards,
