Using

First add this project to your mix dependencies:

def deps do
  [
    {:nerves_time_rtc_nxp, "~> 0.2.0"}
  ]
end

And then update your :nerves_time configuration to point to it:

config :nerves_time, rtc: NervesTime.RTC.NXP.PCA8565

It's possible to override the default I2C bus and address via options:

config :nerves_time, rtc: {NervesTime.RTC.NXP.PCA8565, [bus_name: "i2c-2", address:
0x51]}

Check the logs for error messages if the RTC doesn't appear to work.
