  • Create a new service to manage hall speed sensors and configure it to trigger at a given frequency (1Hz, 10Hz, 25Hz)
  • Use one of the logic input on the teensy to count the number of pulses per interval of time
  • Make the distance per number of tick configurable
  • Generate "boat speed" message in signalk
  • Generate NMEA2000 boat speed PGN from the signalk messages
  • Use a logic analyzer and a pin to measure the jitter of the service and verify that it's reasonable
  • Generate Log message with distance of current trip
