Detailed Description

Abstraction of a dry contact monitor using nrfcxx::gpio::gpiote.

constexpr auto nrfcxx::sensor::contact_internal::utt_per_ts = 256U

staticconstexpr

Divisor to convert from uptime ticks to contact timestamp clock ticks.

This is selected so the 24-bit reduced range uptime clock can be converted to a 16-bit contact timestamp clock with the same representational range.
