LPCOMP with Zephyr on NRF53

[Christian Holland]

I'm trying to get LPCOMP working on Zephyr - from my research online I can see no information about this currently so I'd like to find out how to do this.

According to an example for getting it working on vanilla NCS (https://devzone.nordicsemi.com/f/nordic-q-a/2847/lpcomp-wakeup-example), simply defining the following function will allow the function to be registered as the callback for an lpcomp event:

void LPCOMP_COMP_IRQHandler(void) 

Could you tell me - will this work in Zephyr, or will I have to use some other method to register the callback for the lpcomp wakeup event?

Also, will simply doing what is defined in the lpcomp_init function from that sample work too? Is there anything else I'll have to do?

Thanks in advance!

You can use the NRFX drivers with Zephyr that are located in NCS root/modules/hal/nordic/drivers.
Add #include <nrfx.h> to your main.c file and enable the NRFX drivers with Menuconfig. 

Then you should be able to use the functions in ncs\modules\hal\nordic\nrfx\drivers\src\nrfx_lpcomp.c.
