Hi all, I think writing to the memory by monitoring voltage has it's limitations. For a small project there is a limited time available and there are only these many tests that one can have when testing the instrument developed. So writing continuously should be implemented. In a similar situation but on a different platform, we had implemented i2c implementation of the IC PCF8583. This is an RTC with 256 bytes of RAM. Battery backup is ofcourse essential but number of writes is virtually unlimited and write time is very small. Double advantage was we had real time as well as RAM storage. Will not work if you have larger number of bytes to store.
