I have for some time wanted to (re)write some of the computer games from my younger days as an exercise in programming and for a bit of fun. I recently decided to do this on a very low-res display made from individual LED matrix modules and in the process created a new library to manage the LED panel display.
A recent feature of the Parola library is sprite based text effects. This extends the functionality of the library to include fully customisable, user defined, animated bitmaps to wipe text on and off the LED matrix display.
Here’s how it works.
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.
