I2C storage issue

[malc-c]

Not sure if it's what you are after, but (thanks to other forum members) use the following routine to place the data from a DS1307 into variables which are then used to compare set times and alarms, and these are then saved in the memory part of the PIC and recalled in the event of a power failure

I2CRead SDApin,SCLpin,$D0,$00,[RTCSec,RTCMin,RTCHour,RTCWDay,RTCDay,RTCMonth,RTCYear,RTCCtrl]  ; read DS1307 chip

timeH=(RTCHour>>4)                               'convert the BCD format of the hours register and store in variable timeH
timeH=(timeH &$03)*10
timeH=timeH+(RTCHour&$0F)

timeM=(RTCMin>>4)
timeM=(timeM &$07)*10
timeM=timeM+(RTCMin&$0F)                         'convert the BCD format of the mins register and store in variable timeM
