Decoding The Memory Map

Jim Easterbrook maintains the 'definitive' [http://www.jim-easterbrook.me.uk/weather/mm/ memory map used by the various Fineoffset weather stations.

I have taken this information and created an Excel workbook that allows you to paste in a memory dump and have it decoded into what are thought to be the meaningful values.

Jim also worked out the Easyweather data file format.

The Excel Workbook

The workbook can be downloaded from here: Decode Fineoffset
