j3 2:9b1e5efd9a09 3 * Demo Ard2Pmod Library
j3 2:9b1e5efd9a09 4 *
j3 2:9b1e5efd9a09 5 * Configures mux for desired pmod type and then displays current time
j3 2:9b1e5efd9a09 6 * and date in endless loop after asking the user for input to configure
j3 2:9b1e5efd9a09 7 * the RTC.
j3 2:9b1e5efd9a09 8 *
j3 2:9b1e5efd9a09 9 * Requires TeraTerm, or your favorite terminal emulator, configured at
j3 2:9b1e5efd9a09 10 * 8N1 9600bps
