It works, but not long. The second display shows after some times wrong characters and some times later there are no more characters.
Ok, I swap the physically addresses. Now I have on both displays the same.
What value terminator resistors are you using?If you use each one separately do they each work ok?--- bill
After changing the numbers in the sketch I have the same as before but now on the other display.

If you don't know how to do this the the how to use this forum sticky post.
We don't know for sure which specific display you are using since you haven't provided that information so a lot of what we are providing is speculation.It is time for you to start over again with a simple circuit and sketch that just uses one LCD. If that works OK with each LCD then change the sketch to use both LCDs simultaneously.I would add the other I2C device(s) on next and then the 1-wire device(s). When things stop working you should have a pretty good idea of what caused the problem.Don
I think the reason is the I2C interface. It seems that only one address is possible. 0x20. I will make some changes to the interface and see what happens.
