I am using my board with STM32L081KZ.
I set up irq like this:
gpio_init_int(GPIO_PIN(PORT_A, 0), GPIO_IN, GPIO_FALLING, hall_handler, NULL);
How can I fall asleep now so that consumption is as low as possible and the mcu wakes up on my interrupt?
I read Layered PM Infrastructure and no understand how to use it.
In order to use this module, you’ll need to implement pm_set(). - How to implement?
