Startup problem

Post by steve »

It seems a number of you are having the same problem at startup. Unfortunately I can't do anything about it at the moment (I can't even look to see what the problem is, let alone fix it), so please bear with me.

I don't need any more reports of the problem, so if you are getting a crash at startup with a Fine Offset station, have a look inside the bug report, and see if it says 'floating point division by zero' at about line 25, and something like:

Code: Select all

0069e542 +a06 cumulus.exe EasyweatherUSBUnit   328 +151 TEWUSBForm.ProcessHistoryData
a few lines further down. If it's like this, please don't bother reporting it and I'll look into it as soon as I can.

Following the Startup problems there is also a problem with the rain data. Probably related. Cumulus crashes with the divide by 0 error at the time that it tries to communicate with the 1081 Desktop display. I've given up trying to correct the data for now but apparently there was a cloudburst last night :-)
I'm just rambling on with any info that I notice that may help. Maybe I will just leave the computer on 24/7 until a solution is found.
Good luck with the computer rebuild.

I was sitting on the ferry this afternoon coming back from doing the shopping, and I suddenly realised what this problem is - it's in the code I changed which calculates the rain rate, so yes, you're right.

I changed the code so it takes the rainfall in each logger entry and divides by the 'interval' in the logger entry. The trouble is that the latest (i.e. current) logger entry can have an interval of zero if it's only just started being written to.

So at least I know how to fix it when I am able.
