Usage

• Change the string variable in the printMsg accordingly to what you want the POV to display.
• There are a few preset constant string to test the fonts available:
  • T_NM: Displays the available number set
  • T_AP: Displays the available alphabet set
  • T_SM: Displays the available symbol set
  • T_HW: The classic Hello World to get things started!
• The character limit that can be displayed is set via the MAXCHAR constant, which is set to 35 by default.
• For debugging, enable the DEBUG constant.

Characters

Below are the set of characters that are available for the POV Display:

• Spaces ( )
• Numbers (0-9)
• Alphabets (Uppercase, A-Z)
• Some symbols: ! " # $ % ' + , - . /

If there are characters that are not recognised in the string passed to the printMsg function, it would be replaced with a empty character (or put simply, nothing).
