Announcing phi-2 shield with 20X4 display!

As some of you have waited a while for this. Now it is here, everything about famous phi-2 shield but bigger on the display estate. Instead of a 16*2 character display, it boasts a 20*4 display. It fully takes advantage of the Text-based User Interface software library phi_prompt, which I updated with tons of features for you to use.

    Okay. You have to set the year, month, and day of the month… and then set the day of the week?

    I suggest you google “Zeller’s Congruence”.

      It was a convenience to do it the way I did it to save a few lines of code for each setting. I didn’t say you have to do it whatever way I did. Just make the changes you like but you will have to write a few more lines of code for each setting, no big deal.
