Hi all,

My little odometer is comming along very well. Now I only have one last problem I need some ideas on...

Since this is an odometer, it has to some how retain the current reading when the device is powered off. I tried writing to eprom for every 10th mile change, however thats writing to the eeprom quite a bit and actually ends up messing up the display. So I figure its better to just write to eeprom say, when the key is turned off. But Turning the key off also cuts the power to the whole unit...

I know its a little off topic, but again... just reaching for some Ideas.
