I posted this earlier in a different thread, but it was marked "solved" so I don't know if anyone saw this post:
Well, I seemed to have really messed something up. All was working well until I followed some tutorials about how to set the HWCLOCK.
Now, when I scan using 'i2cdetect -y 1' it shows ports 57 and a UU in port 68 where the DS3231 is supposed to be. The 'UU' is supposedly a conflict but the commands 'sudo hwclock -r' and sudo hwclock -w' entered into the terminal seem to work.
Yet using the i2c Scan node, a port 87 appears. I get errors when I try to use the 'i2c in' nodes to connect to 57 or 68. It will connect to the phantom port 87 but I only receive '255' in the msg.
Can someone tell me what I've messed up here?
