analog pin as a wake-up pin.

[jignesh]

Now,

i have nRF51-DK.

now, i'm use one ADC pin in coding and one wake-up pin for device wake-up.

but i want to remove that wake-up button. and need to wake up device by analog pin. like, when arrive specific voltage(2.3V or grater) on analog pin then device should be wake-up suddenly.

it's possible?

what is wake-up source for that ic. nRF51422 or nRF51822.?

Hi,

Yes, you can use the LPCOMP peripheral to wakeup from system off mode. See chapter 32 and chapter 12.1.5 in the nRF51 Reference manual.

Best regards,
