NRF52 Bare metal - attaching interrupts

[Angus]

I have been experimenting with using some peripherals on the nrf52832 without using the SDK. Primarily of interest to me right now is the low power comparator (LPCOMP).

There is a handy example here github.com/.../main.c but i am having trouble attaching an interrupt to a comparator event. Does anyone have a wee snippet which may help or may be able to point me in the direction of some good resources? The documentation i can find is good but mostly relates to the SDK.

Cheers Angus

The github example does not look like it enables the interrupt, you can do this like below Assuming that you have already enabled the events

NVIC_SetPriority(COMP_LPCOMP_IRQn, priority);
NVIC_ClearPendingIRQ(COMP_LPCOMP_IRQn);
NVIC_EnableIRQ(COMP_LPCOMP_IRQn);

void COMP_LPCOMP_IRQHandler(void
{
    // handle your interrupt here
}
