How to set an interrupt on LDSW via GPIO in the NPM1300 using the nRF Connect SDK.

[Priyesh Shahi]

I am using NCS v2.5.1 and working on a project where I need to turn off the system using a button that triggers an interrupt on a GPIO. I want this GPIO to control a load switch to turn it on and off. Where both the GPIO and the load switch are part of the NPM1300. How can I achieve this using the nRF Connect SDK?

Is there any configuration available in overlay file?

Hi Priesh,

I have taken over this ticket as Sigurd has been assigned to another task. I will check for updates and get back to you.

The pin can be configured in the app. That should fix it:

int err = gpio_pin_configure(pmic_gpio, 1, GPIO_INPUT | GPIO_ACTIVE_HIGH | GPIO_PULL_UP);
if (err) {
  printk("gpio_pin_configure=%d\n", err);

We've tried configuring the pin as suggested, but unfortunately, it's not working.

Here is the code Sigurd supposedly used when he tested the fix he suggested. I verified that the project builds for nrf52840dk_nrf52840. I commented out this line in src/main.c:

printf("Hello World! %s\n", CONFIG_BOARD_TARGET);

EDIT: Adding attachement.
