You may have seen those cool fonts some people use on their MAX7219 displays, well now you can create your own custom fonts for your MAX7219 displays! Without some additional software, the only fonts you can use are the ones included in the library you are using. While there are a good variety of fonts available, they may not always be what you are looking for. In the case of MD_PAROLA (common C++ based library for the MAX7219), the fonts are compiled into the program.
