Hi Guys,
Can anyone help with the correct script, I'm trying to set up the auto logging to start recording at the beginning of a lap & finish at the end of a lap. Cheers.

What kind of event are you doing? Based on the requirements I'd guess you're autocrossing, is that right?

There are a handful of options here - https://wiki.autosportlabs.com/RaceCapt ... g_Examples I have the battery-voltage version working on my Mk1 hardware. I'm having trouble combining it with reading/logging CANBus channels though. Mk1 has limited script memory available...

Code: Select all

function onTick&#40;&#41;
  if getAnalog&#40;7&#41; > 13 then
    startLogging&#40;&#41;
  else
    stopLogging&#40;&#41;
  end
end

I don't mind having some excess non-moving data before and after each run. I prefer that to using a GPS speed trigger, so I don't miss the beginning of the run. Some of our starts have a 90-degree bend before the timing lights, to encourage less speed/burnouts at start, to reduce damage to our parking lot.

You could combine the start/stop logging examples with the function getAtStartFinish() https://wiki.autosportlabs.com/RaceCapt ... nish.28.29

Although I am unsure if that function will return true for a separate start and finish line. You will need some extra code to handle state too.

Thanks guys, we're running jet sprint boats & have tried using auto log Lau with speed & rpm, but we seem to log a lot of small files when warming up etc. making it hard to determine which files are actually laps. Would something like this work? :

function onTick()
if getAtStartFinish() = start
startLogging()
else
if getAtStartFinish() = finish
end
end

You might try that out - just ensure you have your tick rate set to 10Hz or higher, so it has a chance to catch it in the start finish point.

let us know how it goes!
