neopolitan
A library for displaying "text" on LED boards
Description
This is a revamp of stockticker, which queries real-time stock price data, calculates daily fluctuations, and displays it on an LED board. While the end result of that project was cool, this project aims to clarify much of the data display code and make it usable to display any inputted message. See this sub-readme for an introduction to how data can be used to make the board display "human-readable" text.
Given that access to hardware boards can be constrictive and testing can be difficult, this project aims to support data display on a graphical interface so that anyone can access it. pygame is used to display the graphical display, while the neopixel (hence the project name) library is used to interface with the hardware board. The switch between these two displays is OS-dependent.
