BeagleBone

I just received a BeagleBone (for a project at work):

http://beagleboard.org/bone

Naturally I had a go with Oww. After installing a few developer packages (using the opkg system - much like ipkg on Optware) building owwnogui natively on the BeagleBone was quite straight-forward. The kernel driver for the AAG TAI603B was already installed, so no problem. Even a DS9490R works.

Just thought I'd share this news, as the BeagleBoard makes a neat little embedded computer. Its abilities go way beyond running a little thing like Oww of course.

Version 0.84.0 – New Feature - WOW Upload

This version adds upload capability for the UK Met Office WOW format. Please see the WOW home page for registering your station.

New setup/setupNG lines will look like this:

httpwow http://wow.metoffice.gov.uk/automaticreading
httpwowid [Your ID]
httpwowpin [Your PIN]
httpwowon 1

N.B. Corrected 2011-11-23

This will upload to WOW on each log update.

I have also changed the number formatting for uploads.

Version 0.83.3 – Bug fixes.

This release addresses a problem with USB and 32-bit architectures. The previous bug fix for time-keeping had the unfortunate side-effect of stopping USB operations waiting long enough to complete.

There is still an issue with libusb on Optware, as a patch for digitemp has made it imcopatible with Oww. Please use libusb - 0.1.12-1

WSI603B Working with Standard Driver

I recently upgraded my Linux PC to openSUSE 11.3, and I've found that they have adopted the cp210x open-source driver (currently version 0.09). This works "as shipped" with the WSI603B! I presume other distributions will be following suit.

Version 0.83.1

This is a bug-fix release. Please update to this version as 1-wire performance can be pretty ropey with the previous version on some set-ups.

Version 0.83.0

There are several updates in this release:

• This version brings support for the AAG WSI603A wind sensor.
• There is preliminary support for the Hobby Boards ADS wind sensor.
• Added solar data to wund upload.
• I've fixed a bug that caused updates to stop.

Thanks for user contributions.

Please report any issues.

AAG WSI603B 1-wire Adaptor

The Silicon Labs CP2101 USB-to-serial adaptor used in the WSI603B is not well-supported under Linux. The un-patched kernel driver doesn't seem to work. You can try this patch from Paul Erkkila which he has kindly allowed me to post here.

Version 0.82.2 – Bug fixes.

This has a couple of bug fixes, including sending the correct user name and password for Ham Weather uploads. Statistics reset is a bit more sensible for 1-shot operation now.

Version 0.82.1 – Bug fixes.

The main changes affect cwop, swapping two of the rain statistics.

A change to the statistics reset scheme should help 1-shot operation.

I've fed the latest changes into the RISC OS version, but note that I don't recommend using the WUnderground fast update on RISC OS, as there is a memory leak using the http fetcher module.

0.82.0 – Bug fixes and new features.

There are changes for USB 1-wire adapters, new parser output for daily rainfall, support for the DS2760, rapid updates to wunderground.

More details may be found on the News page.

0.81.9 – Bug fix

This (Linux) version fixes a bug in Web uploading.

0.81.8 – Swap to libcurl

This new release brings several bug fixes. But the biggest change, for the Linux version, is that I have swapped from libghttp to libcurl for http uploads. This works much more reliably – libghttp had a nasty habbit of locking up if the network connexion failed during an upload.

OwwClientJ2ME for Mobile Phones

	Read your weather station data on a mobile phone! Updated 2006-05-13, version 1.0.3

Added support for DS1923 hygrochron

Oww now runs on the NSLU2 (Slug). See the News page item, or Skip to the hardware page.

Oww Overview

What is Oww?

Oww is a software project, to communicate with the Dallas 1-wire weather station and other 1-wire sensors, presenting live weather readings, logging data to file, uploading data to weather Web sites, and sending data to other programs through a command line interface.

Operating systems

Oww works with the following operating systems:

• Linux
  • nogui command line version (now works on the NSLU2 "Slug")
  • gui version on systems with X Window and GTK
• RISC OS
  • nogui version (task window)
  • gui version using Acorn toolbox
• MS Windows
  • nogui version only – current version uses Cygwin

Oww Client

Oww Client is a graphical client for Oww.

Oww Log

Oww Log is a logger daemon for Oww data.

Background

One of my previous projects (ThermIIC) used I²C to read values from thermometer ICs. Partly because of the trouble of using the I²C bus over long distances, I recently became interested in the Dallas 1-wire bus. This was used in some RISC OS machines to communicate with the unique machine id chip. To make things fun for us experimenters, Dallas have produced a weather station kit, using the 1-wire bus.

The article

Some time ago I wrote an article about Oww for Acorn User. In the event they let me down, so I have made it available for free, in full, online. Please note that I cannot provide any support for the associated software. Recently I wrote a new article, which was published in Archive.
