Topic: Ws28xx exchange

[pschnell]

Hello,

I found this end week that Ws28xx communicate with PC via a temporary file : WV5DataStore. this file it's in the same folder that currdat.lst.

This file is update with a window service : WV5Communication (Backend.exe in heavy weather program file).

Some body know structure of this WV5DataStore ?

Best regard

That is interesting, I wonder if it is a variant of the history.dat file that is picked up by the application? The reason I say that is because this backend.exe is apparently the process that communicates with the console and is writing the currdat.lst. Unless HW Pro has some other back door mechanism to communicate with the console, it must be pulling the historical data from somewhere.

Let me know if you find out what is hiding in this file.

Thanks.

Hello,

Yes this service write currdat.lst file. But WV5DataStore is more complex. I suppose all currents datas are in, but also all all history data-logger.

I have find that this file is very short when no connexion is. When a connexion is established, this file is more fully.

It does appear that the HW application is talking to the service using a DLL called sHID.dll that is shipped with their installer.

Here are the functions within that DLL:

_sHID_EraseConfigFlash@4
_sHID_EraseDataFlash@4
_sHID_Execute@8
_sHID_Find@16
_sHID_GetFrame@12
_sHID_GetReport@12
_sHID_GetRevInfo@8
_sHID_GetState@8
_sHID_ReadConfigFlash@16
_sHID_ReadDataFlash@16
_sHID_ReadReg16@12
_sHID_ReadReg@12
_sHID_SetFrame@12
_sHID_SetPreamblePattern@8
_sHID_SetRX@4
_sHID_SetState@8
_sHID_SetTX@4
_sHID_WriteConfigFlash@16
_sHID_WriteDataFlash@16
_sHID_WriteReg@12
_sHID_create@0
_sHID_destroy@4

It is hard to say what is in that file WV5DataStore. Have you tried opening the file with Notepad or better yet, a binary file editor?

[pschnell]

Yes, I have found this entry point (not all for me). But this entry is for the service WV5Com. I Think, it's not a good search. I have See that WV5Com continu to work when not HW.
So for me, Why not used this service and try to decode WV5DataStore. An other search is Window messages beethen HW and service.

For open WVDataStore , I have open it with notepad and next week, I try to make a event on modification on this file.

Hello,

I have try to join LaCrosse for Ws28xx protocol.

It's Clear.
Lacrosse Technology is unresponsive to user exits to provide software crap. So if you want to buy a ws28xx and link with a Mac or Linux, do not expect anything.

[wuhu_software]

Yes, that is why I will not recommend a La Crosse or OS to anyone.

We need to ban together and refuse to buy from them until they open up their protocols.

Davis Vue is open, Peet is Open, use your voting dollars wisely.

 People here are just an handful there lot of folks out there running stations that never hook up to internet and move data  so that is an protest you will never win. Be kinda like those odf us in Alaska trying to get Davis to  make the thermometer go  to 50 or 60 below  rather then there 39.3 below and quit.

[wuhu_software]

Well, if we post enough reviews, like on Amazon, that may change.

There is one way to get weather data and show it on the web...

HW Software always on top receiving data from the station.
Another program that converts *.dat file (last record from it I mean) to txt, xml or sending data to mysql database.
Information about structure of the *.dat file is on the web - ask uncle google or look under

For the LaCrosse WS2800 IT (and probably for some of WS3xxx):

File without header. One record - 56 bytes block.
8 Bytes (double) - DateTime (Delphi type)
4 Bytes (float) - Absolute Pressure (or constant = 10101010 - not real pressure)

Any new info about how to use sHID.dll? Somebody broke this?
