Storing Information

ghost13

I am developing an altimeter and I need a way to log approximately 3000 samples (each sample consisting of a four digit number and the time). So, what is the best way (and smallest way) to store this info? An EEPROM (I've never used one before... is there an appnote?)?
Also, what is the best way to keep track of the time? I only need information like the number of milliseconds since launch.

Thanks!

I would recommend something like the Parallax Datalogger or Hitt Consulting's data logger. I'd suggest the one from Hitt Consulting since it's smaller and lighter. Both come with examples of their use and these are downloadable from their websites.

Timekeeping will be harder. There are plenty of real time clocks that will give you a time in seconds, but won't give you anything finer. I suspect you'd be better off using something like an SX rather than a Stamp. You could program it in SX/B which is (deliberately) similar to PBasic. It could easily interface with an EEPROM ... there are examples available and it can do the timekeeping itself, certainly to millisecond resolution.
