Hi,

Take a look at the example under "examples\peripheral\rtc". You will need to declare a void function for "RTC0_IRQHandler", see the declarations of irq_handler and nrfx_rtc_0_irq_handler in nrfx_rtc.c, and the define in line 104 in nrfx_irqs_nrf52840.h

// TIMER0_IRQn
#define nrfx_timer_0_irq_handler    TIMER0_IRQHandler

#if NRFX_CHECK(NRFX_RTC0_ENABLED)
void nrfx_rtc_0_irq_handler(void)
{
    irq_handler(NRF_RTC0, NRFX_RTC0_INST_IDX, NRF_RTC_CC_CHANNEL_COUNT(0));
}
#endif

You can also take a look at this snippet here.

Hi,

Thank you for your reply.

I am looking for some info to actually setup the interrupts handler in the code. I have set all the registers to run the RTC and that seems to work ok, but I would then like to catch the interrupts on the TICK event, but I can't find any info about how to setup the interrupt handler in the code.

Hi,

It is much easier to use our drivers directly, the GPIO driver is documented here. We have an example which demonstrates interrupts on pin changes in our SDK, documented here. If you still want to address the registers directly you will need to look up the registers in the Product Specification, here.

Best Regards,
