V2.0 Clock Visuals Question...NTP/GPS - 29/08/2001 11:12
This may be the makings of a wish list item... I've read about new clock visuals in version 2.0. Is one of these a plain HH:MM:SS 12-hour clock format? I'm looking at the easiest possible combination of clock + stopwatch funtions to have in the car for local TSD rallies, and the best possible clock solution I can think of is to have an HH:MM:SS clock taking up the entire Empeg display. These events usually take place in evening, so visibility should not be a problem, esp if the clock uses simple "brightest" block numbers (no fancy shadows or anything).
This clock needs to be synchronized. I fetched a program from the BBS that grabs time from a serially-attached GPS and am going to try that out. So long as we only use it for clock function (not that knowing our lat/lon would help, but knowing GPS-provided speed over ground could be considered cheating), I don't think we'll be violating Novice or SOP (seat of pants) class rules. I've also downloaded debian arm NTP binaries. My idea is as follows: If Empeg boots up at home, have init load ntpdate and get time from my local NTP server (Linux file server with a GPS), if it boots up in car have it get time from GPS antenna in car (at least initially...I haven't looked a cron/scheduling facilties in Empeg).
Hey, next TSD is on 14 September, so if you want to release V2 just in time for that, that'd be swell!
