Hi Jim,

Thankyou very much for your very quick and helpful reply.  This has been bothering me for quite a while.  I should have posted my question years ago!

I knew that I2C could accommodate multiple devices via their addresses, but since I had never seen any one use two devices with a MM, I thought the MM implementation might have been limited.  It seems that I did GeoffG a disservice.  Sorry Geoff!

OK, I will just try it.  I usually update the time from the RTC every 10 minutes as in the SuperClock, so it will be addressed regularly.  (I also borrow the SuperClockFonts, which are great!)

I probably should try rolling my own I2C commands for the DS3231 - it might be a good way to start growing my skills.  The most ambitious thing I have done so far is just to get the temperature out of it using RTC commands.

Thanks again Jim,

Lew.
