My data logging project

Im a newbie to data logging with arduino and its on my to-do list to get me a decent size eeprom chip for my next project which i might aswell explain so my question is put in context.

I ride motocross at the local track and wish to mount an accelerometer with an axis lined up with my suspension to measure the acceleration (integrate twice = displacement?) of the fork while i ride over jumps bumps etc for 2-3 laps or so.

A lap time will be around 150seconds.

The purpose of this is to put the data into excel and plot displacement vs time and then make adjustments to my suspension and repeat.

Since the suspension is moving rather rapidly i think a resolution of 500ms would be necessary in order to get a reasonable picture of the systems response.

So now say i have acheived this and filled up my eeprom with data and have pulled into the pits ready for the laptop. How do i go about grabbing the data out of there and putting it into something useable for graphing in excel?

Also any suggestions for my project are welcome,

Thanks

You could do this: Comma-separated values - Wikipedia

Save the data in a sequentional file, and delimit the data using commas.

(you will need a function for printing all the data to the serial port, and some way of capturing the data. [the serial monitor in arduino IDE will suffice, just copy&paste into notepad or whatever])

For looking at input data from the board a small c# program is realy simpel to make, and coud easy be reprogrammed to save data or trow it in a sql database for future use.

I'll give a url here for a "guidet tour" of this sample program:

(sorry for not making a active url but its my first post here on the forum, soo aint allowed to.)

has to say i dident write the guide, but have redone it my self a lot of times for different purpes, and it works great.
