PeterPan321:
And then there is the old adage "don't fix it if it ain't broke".Any Thoughts or advise?
How true.
I have had an RTC and a 4x20 LCD running together, more or less continuously since 2012, and I didn't know I2C could lock up until I read this. I don't use any library for RTC but the other libraries are just what comes out of the box. I only opened this thread because I was silly enough to think it was something about telling the time, and I rather feel that the only bit worth reading in its entirety are
it has not happened EVER during normal operation.
and I note your capitals with some relief......
