Basic Stamp Data logger
I am looking for any advice on using a Basic Stamp to log data into the EEPROM and then at a later time retrieve that data into an excel spread sheet.. What I am after is logging Temperature and Humidity once an hour for 24 hours and then linking up to my computer and plotting the data in excel... I have gotten the Temp/Humidity sensor to work and the Real Time Clock to work, now I just need to figure out how to get it all together..
Thanks.
Thanks.

For the logging, read the chapters in the Stamp manual on the READ / WRITE statements.
You would either have two separate programs (one logger, the other uploader to PC) or have one program with some kind of switch to select between the two functions on a reset.
As Mike Green Mentioned, look at the book What's a Microcontroller (if it didn't come with your stamp, you can download from parallax) - Chapter 7. It uses a photoresistor as the resistor in an RC circuit. It logs and saves the time to the EEPROM.
As part of the exercise, it leads you to download StampPlot Lite from www.selmaware.com - when you go there, you'll find that the full version is now free for personal use. This may be one solution.
While doing this exercise, I also stumbled on http://www.parallax.com/tabid/393/Default.aspx which is the PLX-DAQ Data Acquisition tool. Looks like this may directly do what you are looking for (I haven't gotten to playing with this yet).
So good luck - and hope I'm not sending you astray.
