The Parola Library

The Parola library is implemented to work with the MD_MAX2XX library. It depends on the MD_MAX72xx library for hardware control and will run on all hardware supported by that library. The MD_MAX72XX library can be found here.

This software library implements functions to simplify the implementation of text special effects on the Parola display.

• Left, right or center text justification in the display field.
• Text scrolling, text entering and exit effects.
• Control display parameters and animation speed.
• Multiple virtual displays (zones) in each string of LED modules.
• User defined fonts and/or individual characters substitutions.
• Double height and vertical displays.
• Support for mixing text and graphics on the same display.

The latest copy of the Parola Software and hardware files can be found at the Parola distribution site.
