can't work this out... i finished soldering everything onto a board for one of my loggers (18x 3 channel datalogger)
it has 1 24lc256 on it as well
what gets me is why after i set the time then remove the power ... the rtc doesn't have a backup battery so i know it's supposed to clear but instead when i powered it up again after the initial time setting bit is done all the values just say 255
is the rtc not really good for on/off apps or does it have to have a backup battery
it will reset and work properly after about 5 mins though but i'm wondering does it have an internal capacitor that tries to eep it going or somthing
