10.6.1.28 NMEA Input
Type
:
Serial Receive
GPIO Port
:
2
Auxiliary
:
Receive
Description
:
This function accepts external data in the NMEA 0183 format. Advanced Navigation
recommends against using NMEA 0183 input wherever possible due to the inefficiency,
low accuracy and precision and weak error checking of the format. All NMEA messages
received must have a valid checksum. Supported messages are listed below. The
recommended combination of messages are GPGGA, GPVTG and GPZDA with optional
messages GPGSV and GPGSA.
