After some initial testing I decided to up the ante on the phi-2 shield
display area and released this variant:
My phi_prompt library
is better utilized on this larger display. Here's my alarm clock version 4 on the shield:
The project code conforms to the size of the display (16X2, or 20*4), just set the #define to your display size.
The project code is on this page: (in the middle)http://liudr.wordpress.com/shields/phi-2-shield/
Now a lot more projects can be better done on this shield. I will still be offering the variant with 16X2 displays since most projects can be accommodated with 16X2 display.
