Thanks December 12, 2014 at 7:22 pm #2126 MichaelKeymaster Yes, if you choose pins that are not already being used, that could work. Which pins do you need? What kind of interface does the RTC have? SPI? Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In Log in / Register
