Parola is nice library with various animation function to show texts to dot matrix display with MAX7219 controller.
There are excel macro and exe based tool to create your own customized fonts included in library.
I’ve also created simple font editor which reads font header file and writes out to header file format.
For Windows, use at your own risk.
Create new from scratch, or start with font file such as included in sample sketch of Parola library. One font data per font file is supported.
Name is font name. Comment is saved as comment in header file. Fixed width will create fixed pitch font. Set Auto for width to auto set text width.
Left mouse button to place dot, right mouse button to clear dot.
