is there a way to get lap times on a oneway track? I've tried out racechrono on a local hill road. Start is at the submontane, finish at the summit. I go backwards the same way. I've defined start and finish line, but I got no lap times. What I am doing wrong?
Thanks in advance.
Notice the traps are uni-directional as default, so you need to go through them same way as when setting them. If you went the other way when setting them, you can disable the "uni-directional" setting from trap settings, or rotate the trap 180 degrees.
If you want to go same track two ways (up and down), I recommend you create two separate tracks. This way the graph analyzing works much better.
I hope this solves your problems.
thanks a lot for your assistance. I've followed your instructions as well as the manual on this website.
But.... at the end there are no lap times so far. May I send you my my session, plot, nmea and track files for checking? Maybe there is something wrong with my installation on my PDA or with something I do not know at the moment. By the way, I am using my internal GPS which as a 0.3 Hz rate? Does it matter in that case?
Greetings from Germany,
That 0.3 Hz GPS sounds it might be the reason. I remember vaguely programming the traps so that they are not registered if there is not near enough plot...
Can you configure the GPS back to 1 Hz, or is it hard coded like that?
BTW: I won't fix the issue with 0.3 Hz GPS as no one else has complained yet (should be very rare problem, as almost all GPS receivers are at least 1 Hz). The RaceChrono engine does not register the crossing of the traps, as the plots are too far apart time wise, and thinks the data is not reliable enough.
