Heavy Weather Maximum/Minimum data

<< < (2/2)

--- Quote from: "Colin Miles" ---HW is set to sample every 10 minutes. At various times, when convenient, I download these to my computer onto the history.dat file. I then save these as text. These are then read into my program. This is set up to recreate monthly and yearly text files. The program then creates whatever graphs and data that I require.

Does the history.dat file contain the max/min data? If it does then presumably there is some way of extracting it.

I don't publish to the web. Many thanks for your replies.

I am pretty sure that it does not contain min/max.

It is impossible to determine the logic that the console uses to store the data as it is collecting it at a frequency. For example does it record the extremes during the 10 minute sample period or does it just take a snap shot. My guess would be a snap shot at the end of the 10 min period.

Heavyweather is probably reading the extremes from the console that are stored in a different area on the console from the standard 10 min snapshots. You probably can not access that information via the history file.

Colin Miles:
Thanks. I was hoping that someone would know how to access the min/max data in the same way that the HW program does. Or maybe that a HW programmer would be willing to divulge how it is done?

You should look in to the open2300 project.

http://tech.groups.yahoo.com/group/Lacrosse_weather_stations/

It is an open source (C source) project that will allow you to read the memory of the console directly.

You can not have both the HW application and the open2300 access the port at the same time, but with your own application, you will probably no longer need HW.

Colin Miles:
Many thanks!

Colin,

No problem, let me know if you need help with it.

You can also use my application if you are running your computer 24x7 to upload your data to the weather servers. You can run with or without (recommended) HW.
