I'm new here... and I'm kind of interested in this. cause I need to save 10 entries only in my EEPROM and I want to stick with Halley's template. So here are my ideas. I have a DS1307 which will give me timestamps therefore the length of the string will be constant. Beside each timestamp I have some float values I'm estimating that I'll need 12bytes per entry. As mentioned I may have problems with reading them out later. Any ideas guys? Thanks in Advance
