Is there an easy way to build a display that will show some chosen NMEA
data?
I have seen on the market programmable units that sell for several
hundred $ and I know that a computer is easily interfaced but what I
need is just a simple, cheap and weatherproof repeater at the helm to
display only few of the zillion data available at the underdeck main
navigation station. For example decoding just part of BWC and VTG and
displaying, say, four lines would be enough (COG, heading, bearing to
waypoint, and distance to waypoint).

There is an NMEA-0183 FAQ on my website listed below that details the
formats of common NMEA-0183 sentences.

There is a simple program to display some NMEA data somewhere on my
site, called "nmealogr.zip" (or maybe ".exe") This was written in
Borland C for DOS, but the source code should be a useful guide for
other environments.
