Hi
I'm designing a power monitor and am going to have a portable display that stores various values over time. This is wirelessly connected to a detector circuit that uses a cs5463 ic.
My question is, would using eeprom be ok for writing to quite regulary. I'm planning to be able to show values that will be cumulative over time (around a months data or year if possible). It would be things like max current, cost of power over a week etc.
I beleive this will require a lot of re-writing data stored and have read that eeprom isn't great for this?
I'm using a PIC18F4520 and the eeprom I am looking at is the 25LC1024 from microchip.
The unit is going to battery powered so need non voltaile memory thats cheap. I was thinking that I could reduce the number of writes by storing the data in on chip memory then periodically write this to the eeprom so would only lose a bit of data.
Its only designed for use in domestic situation so accuracy isn't crucial so can afford to lose some data.
Thanks for your help
