Data Logging

[barkerben]

Hi,

I'm putting together a system to talk to a GPS board I have. It will do various things, such as output to an LCD etc. I wanted to do some data logging - record waypoints, track position every x seconds, etc.

Serial EEPROM seems to be the way to go. But 1 Million write cycles is not neccesarily as much as it sounds if you are recording a few bytes every few seconds. Does anyone have any thoughts...?

Cheers,

Ben

I found a few other posts on this site. I also found a site here:

This talks about writing to CF using a POC, but seems to be for a different distribution of Basic...?

Look into FRAM from www.ramtron.com

Ben, every BYTE can be written to 1 million times. Surely you don't fill your entire memory every few seconds.

Ah... every byte. That makes a lot more sense, now I come to think about it!

Interfacing a serial EEPROM to a PIC should be quite simple. I still need to find an easy way of getting the data out of the eeprom and onto a PC, which is why the CF idea seemed nice. But probably far more complicated...

Ben,

have you had a look at This Thread ?
