Description

Nordic nRF LPCOMP (analog Low-Power COMParator)

The following example displays the minimum node layout:

  comp: comp@deadbeef {
          compatible = "nordic,nrf-lpcomp";
          reg = <0xdeadbeef 0x1000>;
          interrupts = <0 NRF_DEFAULT_IRQ_PRIORITY>;
          status = "disabled";
  };

Enabling the comparator node requires setting the default
configuration of the comparator.

The following example displays enabling the comparator
using an internal reference:

  &comp {
          status = "okay";
          psel = <NRF_COMP_AIN0>;
          refsel = "VDD_4_8";
          enable-hyst;
  };

To select an external reference, select the "AREF"
reference and add the external reference:

  &comp {
          ...
          refsel = "AREF";
          extrefsel = <NRF_COMP_AIN1>;
          ...
  };
