The above graphic, and, if you click on it, graphs, are generated from the data collected from my 1-Wire Weather Station, located in Abbot, ME. That's Lat 45.203051 / Lon -69.465875 for all you GPS or ICBM-centric folks. The technology that the weather station is based on is from Dallas Semiconductor (www.dalsemi.com), and the station was purchased from Automatizacion Aplicada a Gasolineras S.A. de C.V. (www.aag.com.mx). The folks at AAG were incredible, and I had the station 24 hrs after I had the shipping confirmation.
I'm one of 'those Linux nuts', so I'm running a Linux box that the station is attached to, and using dalweathdb to provide the data. The data is being written to a local MySQL database and being replicated to the MySQL server on buoy.com. Oh, the Linux box attached to the station is dialup only, so it only connects to the local ISP (Kynd Internet www.kynd.net) every hour.
Introduction to Dallas MicroLan... Source code for accessing the Dallas MicroLan, aka 1-Wire system, as used in iButtons Dallas is now part of Maxim.
Dallas MicroLan Counter, DS2423... Source code for accessing Dallas DS2423 counter, a MicroLan family chip.
Dallas MicroLan ADC, DS2450... Source code of almost working software to read 4 channel analog to digital converter. If you know the Dallas chips well, I'd be very grateful if you could look at this, even if you're not a Delphi programmer, to see if you can spot my mistake! Channels A,C and D read properly, but not channel B! Yes... I've checked the signal being sent to channel B.
