How to config PiFace RTC module

    • Official Post

    It would help to know what chip is used - the piface documentation is a little sketchy at best.
    It would also help if you could link the install script as that might help.
    It may be as simple as adding dtoverlay=i2c-rtc,<chip> to /flash/config.txt but if the chipset is not included in the kernel, then you are out of luck.
