simple NMEA display
Daniele Fua wrote:
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). Daniel When you say 'build', what is your experience level with hardware and software. There are a number of microcontroller development kits that can do what you want. Displays available range from 2x16 character backlit alphanumeric LCDs to QVGA (quarter VGA) bit-mapped graphics. This outfit: http://www.parallax.com/ sells a range of products that can do what you want if you have the skill to cobble some hardware and code together. If that's beyond your skill level or your time is worth too much, a ready-made unit is a better choice. The good thing about some of these kits is that there are enough users groups on-line that someone may already have solved your problem for you. Or something close enough. -- Paul Hovnanian ------------------------------------------------------------------ At some point it becomes necessary to behead all the architects and begin construction. -- Abi-Bar-Shim (Project Mgr. - Great Pyramid) |
