Use an interrupt on a GPIO pin to increase a uint32_t counter.

Exact goal with this data TBD (and defined in another task).

Potential goals:

  • Use it to re-set the sync time once-per-second
  • Use it to solve how out-of-sync the system is getting

Other notes:

  • Ensure that, when the power to the GPS is turned off, then any interrupts must be disabled.
  • Create a telecommand to enable/disable this behaviour: gps_set_enabled_pps_tracking()

Can I get some one to look over my code so I can check with electrical to test the functionality. THX
