This is a VGA demo that runs without input, but also accepts 8-bit input on the ui_io[7:0] pins to display a virtual 7-segment LED display (with decimal).
Plug into a VGA monitor, select this circuit to test, and reset.
To test the user input functionality, connect the ui_io[7:0] pins. The idea
is that this would be a possibly useful graphical extension to the dozens of
existing projects that utilize the 7-segment LED display to show results.
Requires the TinyVGA PMOD
