POV (Peripheral of Vision) Display ; Displaying temperature and time

Hi All,

I’m in the process of creating a POV (Peripheral of VIsion ) display with the Beaglebone Black. I intend on displaying current time and temperature. I’m trying to figure out a way to access the time on the Beaglebone and values from my temperature sensor in C so I can display this information. Perhaps storing the numbers as integers? Any input would be helpful. Thank You.
