Hi,

Are you able to run the unmodified example and get the results that is described in the documentation?

Note that LPCOMP_CONFIG_DETECTION has to be set correctly for the application interrupt to enabled. For example in the unmodified example, LPCOMP_CONFIG_DETECTION is set to DOWN, meaning that only DOWN events will result in a application interrupt.

regards

Jared

I have applied vcc to AN2 (input) and taken internal reference vdd/16 so its expecting RESULT should 1(above) .

is it necessary to add NRF_LPCOMP->TASKS_SAMPLE=1; in while loop???

What are you measuring and what do you expect the RESULT register to show?
