The key function of the Parola library is to display text using different animations. From version 2.7 onwards, Parola allows user code to manage mixing graphics with the text. The extensions to the library and what they do is the subject of this article.
Some time ago, I wrote about device independent control of monochrome LED cubes (see this previous blog post which contains information referenced in this article).
Recently, someone contacted me about extending this framework to color cubes for a project they were considering. As it turn out, this was relatively straightforward and has added additional capability to the existing MD_Cubo library.
