ArduTronic – RTC Uhr port umstellen

why does the i2cdetect always gives UU on my RTC in embedded Linux


$ lsmod | grep rtc

If you seen an entry of rtc_ds1307, (like this -> rtc_ds1307  17394  0 ) in the output of above command then this driver might be in hold of that address.

If the driver is loaded in system then unload it using

$ rmmod rtc-ds1307
