Hi,
I am just starthing to get to grips with my Stalker - not getting any joy yet & wondering if a little help might be in order?
So this is what I have done:
Downloaded the sample code and opened in Arduino.
Downloaded the DS1307.H library (not in location indicated by demo code - got it from Seeeduino DS1307 page)
Downloded the FileLogger.H library (not in location indicated by demo code - got it from Seeeduino SD Card Shield page)
Formated the mSD card on a Canon camera and inserted.
Created an empty data.log file on the card.
Compiled the code onto the stalker via Arduino 0017/ATmega 168 - all transferred fine.
Waited several minutes and checked data.log for content.
The only error I got was when adding the FileLogger.H library: you may need to use Tools -> Fix Encoding & Reload to update
the sketch to use UTF-8 encoding. If not, you may need to delete the bad characters to get rid of this warning.
I ran the Fix Encoding & Reload tool and as far as I can tell that fixed the problem.
It all looks like it should be working but no data is getting recorded.
Any help would be appreciated.

This is a demo code for Seeeduino Stalker. It record the sensor
data into SD Card every 5 seccond .
In this demo code , it include two library : FileLogger and DS1307.
You can download these two library here:
http://www.seeedstudio.com/depot/images/produce/FileLogger.rar
http://www.seeedstudio.com/depot/images/produce/DS1307.rar
Remenber to add a data.log file in your SD Card first.
