MD_Parola Fonts - where can you see them, how do you change them

Using Arduino Programming Questions

Hi all,

I've googled & hunted the forum. Is there anywhere that you can see a selection of the alterantive fonts for the MD_Parola library for the MAX7219 LED Matrix Display?

I haven't yet got to the part of telling the code to use a different font, in part cos I can't find one I want to use without looking at it.

Can anyone provide a link to demo pics of the different fonts please?

And if someone wants to point to an article on how to then use them that would be awesome.

I'll keep hunting.

When looking for libraries, search on the libraryName.h... I like to start with the "Arduino >> Reference >> Libraries" link and clicking the "Read the Documentation" link... rather than going straight to the Github link.

That is how I found this Parola_Fonts .INO

Thanks, already been there. Not looking to change languages. I'm looking for fonts that are eg. bold numbers for a better looking clock, or that at least have standard width for all digits.

The clock I've currently programmed the 1 is a column narrower than all the other digits so it looks odd every time a 1 is used in seconds - changes the whole width & moves over a character.

But thank you for pointing out that file.

If anyone has any links to better fonts than the single line standard fonts that would be great. It seems at this point what Parola appears to be lacking that is found in max7219.h/fonts.h that I used in a different project.

Example of what I'm trying to find.... This is using max7219.h/fonts.h in a different sketch.

"Kerning" is what gives proportional type even spacing between characters. You want monospace.

If you will use only static placement of 0 through 9 and a colon, maybe use LedControl.h or MAX_72xx.h and bitmap numbers as you want them to look?

The fonts are 'held' in the MD_MAX72xx library. You will find the tools to edit and view fonts in that library.
